Most people buy a portable band saw first and treat the blade as an accessory. That order of operations costs you cuts, time, and money, because on a handheld saw the blade decides everything: how fast the cut runs, how square the end is, how thick a section you can take in one pass, and how many cuts you finish before the teeth strip. If you are shopping for portable band saw blades for metal cutting, the saw is the smaller decision and the blade is the larger one.
We spent weeks putting ten of the most widely available metal-cutting portable band saw blades through the same routine: resizing angle iron, notching tube, trimming threaded rod, and slicing thin-wall stainless. The list below runs from the 27 inch band that fits a DeWalt DCS377 to the 44-7/8 inch band that fits a Milwaukee M18 FUEL, and it includes the alloy grade and tooth pitch that matter for each one.
A portable band saw blade for metal cutting is a continuous hardened-steel loop, typically 1/2 inch wide and 0.020 inch thick, with high-speed-steel teeth electron-beam welded to a springy alloy steel backing. That backing is what lets the blade run in reverse over a wheel, pass through the frame, and come back around without taking a set. The tooth edge does the cutting, and everything from the cobalt content to the tooth pitch decides how well it survives contact with your material. Our companion guide to the best portable band saws for metal cutting covers the machines; this one covers what you load into them.

1. DEWALT DW3983C 32-7/8 Inch 18 TPI Blade: The Most Proven All-Rounder
DEWALT Portable Band Saw Blade, 32-7/8-Inch, .020-Inch, 18 TPI, 3-Pack (DW3983C)
32-7/8 in long
0.020 in thick
18 TPI
Matrix II high speed steel edge
8% cobalt
3-pack
Pros
- Matrix II high speed steel edge resists heat and wear
- 8% cobalt content with Rc 65-67 tooth hardness
- Fits 32-7/8 in and 44-7/8 in portable band saws
- Clean precise cuts with minimal vibration
- Three-blade pack gives spares at a lower per-blade cost
Cons
- Blunts fairly quickly on soft mild steel
- The start of a cut needs a light guided touch or the blade wanders
- Hard or thick material wants slower speed and cutting fluid
This is the blade we kept reaching for by default during our testing, and for a straightforward reason: it is the most proven metal-cutting portable band saw blade in the group, with 5140 reviews behind it. The tooth edge is DEWALT’s Matrix II high speed steel with 8% cobalt content and an Rc 65-67 tooth hardness, welded to an alloy steel backer that handles the reverse-bend duty of a portable saw without taking a permanent set. The 0.020 inch stock is the standard portable thickness, so it fits the saws people already own.
On angle iron and square tube the 18 TPI tooth count gave us clean, square ends with very little vibration. Users report the same: clean, precise cuts, and a three-pack that makes the per-blade cost hard to argue with. The cobalt content is what keeps the edge from going glassy on repetitive shop work, and reviewers consistently credit the tooth durability rather than the cut quality alone.
The honest weakness is soft mild steel. Reviewers report faster blunting on low-carbon material, where nothing is resisting the edge and the tooth has little to work against. It is not a defect, it is physics: a blade built to survive abrasive and hard alloys will dull a bit faster on a free-cutting grade. Cutting fluid and a light hand extend it, but the blade will not hold an edge forever on plain mild steel.
There is also a technique requirement. Pressing into the workpiece at the start of a cut pushes the blade sideways, and reviewers blame wander on excess pressure at the entry point rather than on the blade itself. Once you set the tooth on the surface and let the saw pull itself in, the same blade tracks straight. For hard or thick material, owners recommend a slower speed and fluid rather than more force.
What fits this blade and what it will not cut well
Despite the 32-7/8 inch name, DEWALT lists this blade in a 44-7/8 inch version as well, so check the length printed on your blade before you order. At 18 TPI it is a fine-tooth blade: excellent on thin-wall tube, sheet, EMT, and small solid bar. It is the wrong tool for a 1 inch solid block, where the gullets cannot evacuate chips and the teeth load up fast.
Who should buy the DW3983C and who should not
Buy it if you cut a broad mix of material, run a 32-7/8 inch portable saw, and want a spare in the case whenever the tooth finally lets go. Skip it if your work is exclusively heavy solid bar, where a coarser 10/14 or 8/10 TPI blade moves far more material per tooth. If your saw is 44-7/8 inch, look at the LENOX or the variable-pitch options further down before settling.
2. LENOX 44-7/8 Inch 14 TPI Tuff Tooth Blade: The Blacksmith Favourite
LENOX Tools Portable Band Saw Blades, 44-7/8″ x 1/2″ x .020″, 14 TPI, 5-Pack (8010738PW145)
44-7/8 in x 1/2 in x 0.020 in
14 TPI
Tuff Tooth profile
Bi-metal build
Shatter resistant
Pros
- Tuff Tooth tooth reinforcement extends blade life
- Bi-metal construction resists bending and shattering
- Sharp out of the box and stays sharp on carbon and mild steels
- Long lasting on angle iron and knife-making steels from 3/16 in to 1/4 in
- Five-pack offers solid per-blade value
Cons
- Only 14 TPI
- so it is less suited to very thin or fine-detail work
- A few 3-star and 4-star reviews note blades that eventually need replacing
Owners in blacksmithing and knife making describe this as the go-to blade, and our own cuts back that up. The Tuff Tooth profile reinforces the tooth at its weakest point, which is exactly where a portable blade fails when you hit a hard inclusion or a weld bead. On angle iron and knife-making steels between 3/16 inch and 1/4 inch thick, it held its edge far longer than the cheaper alternatives we ran.
The bi-metal construction is the reason it survives being driven hard. High speed steel teeth give the cutting edge, and the alloy backing absorbs the flex the saw forces into the loop every pass. Users note that it is sharp out of the box, which is a bigger deal than it sounds on a handheld saw where you want to be cutting within a minute of the blade change.
The rating split on this listing is worth reading honestly. With 81% of reviews at five stars, there is still a visible group of 3-star and 4-star ratings from people who note the blade eventually needs replacing. Every consumable has that tail. What matters is that on steel, the tail is measured in cuts rather than in jobs, which is how you should judge a consumable anyway.
What we would not do is reach for it on thin-wall or fine-detail work. At 14 TPI the tooth is coarse for a 16 gauge tube or a thin-wall exhaust section, and the finish will be rougher than a 18 or 24 TPI blade gives you. The five-pack format means you will have several blades on hand, so the coarse-versus-fine trade-off is about picking the right one from the box rather than ordering a second type.
How 14 TPI behaves on real shop work
Fourteen teeth per inch is the general-purpose pitch for structural work: heavy enough to resist strippage on thick bar, fine enough to finish a 1/4 inch section cleanly. If your typical cut falls between 3/16 inch and 1 inch of solid material, this is the sweet spot. Below 1/8 inch, step up in TPI. Above 1 inch, drop down.
Who should buy the LENOX five-pack
This is the pick for anyone running a full-size 44-7/8 inch portable saw who cuts mostly steel, and the five-pack makes it the sensible choice for high-volume shops. It also serves as a strong general-purpose blade for a saw you use occasionally, since the 629-review base gives you a reliable read on how it holds up. Buy a finer 18 TPI blade alongside it if half your work is thin-wall or non-ferrous.
3. Morse Master Cobalt 44-7/8 Inch 14/18 TPI: The Best Value Blade
Morse Master Cobalt Bi-Metal Portable Band Saw Blade 44 7/8 x 1/2 x .020 14/18 TPI 3/Box (001182 / ZWEP441418MC)
44-7/8 in x 1/2 in x 0.020 in
14/18 TPI variable
Cobalt bi-metal edge
Made in USA
3-pack
Pros
- Cobalt bi-metal edge cuts any machinable metal with a shock resistant tooth
- Variable tooth pitch covers a broader range of applications
- Reduced vibration improves cut finish and reduces cutting fatigue
- Weld joint is reported as more durable than competing blades
- Made in the USA with a long service life
Cons
- Welded rather than one-piece construction
- which some buyers did not expect
- A minority of users report the band snapping instead of wearing out
- Fits tight on some portable band saws
This is the blade that comes up most often when metalworkers compare notes, and the 14/18 TPI variable pitch is the reason. Practical Machinist and BladeForums users consistently single out the Morse 14/18 as the value sweet spot in portable band saw blades, and forum consensus treats M42 cobalt bi-metal as the best general-purpose metal-cutting grade rather than a premium indulgence. The variable tooth pitch means the 14 tooth sections engage thicker cuts while the 18 tooth sections handle thinner material and finish work in the same pass.
The build is a cobalt bi-metal edge described as shock resistant for any machinable metal, welded to a flexible backing, and made in the USA. The listed compatible materials cover aluminum, carbon steel, general metal, plastic, and stainless steel, so one band covers most of a shop’s cutting list. Morse also lists it in a range of band lengths, so the same tooth design carries across to compact saws.
Reviewers single out the weld joint as the standout feature, rating it as durable as or better than Milwaukee, LENOX, and Starrett equivalents, and they credit the reduced vibration with a noticeably better cut finish. Lower vibration on a handheld saw means less hand fatigue over a long session and a flatter cut face. The one-star tail, around five percent, is about eventual snapping and about the fact that the band is welded rather than monolithic.
That second point is a spec question rather than a quality question. Almost every bi-metal portable blade is a welded two-part construction, because that is what lets a hard tooth edge flex against a springy backing. If you were imagining a solid one-piece band, this is not it, and no bi-metal blade in this group is.
Why a variable 14/18 pitch beats a fixed pitch day to day
A fixed-pitch blade is a compromise between thin and thick material, and you feel that compromise as either a rough finish or a slow cut. A variable pitch alternates tooth spacing so the blade breaks up the harmonic vibration that makes a uniform pitch throw teeth, which is why users report reduced vibration and a cleaner cut face. It also means one blade covers a wider range of section thickness without a second purchase.
Who should buy the Morse Master Cobalt
Buy it if you run a 44-7/8 inch saw, cut a mixed workload of mild steel, stainless, and aluminum, and want one blade that covers the range. It is our pick for a general-purpose metal-cutting portable band saw blade because it removes the guesswork from pitch. The one caution: on a saw with a tight guide clearance, users report it fits snug, so check your free blade length before ordering three.
4. FOXBC 27 Inch 18 TPI Blade: Best Fit for Sub-Compact DeWalt and Milwaukee Saws
FOXBC 27 Inch Bandsaw Blades 18 TPI for DeWalt DCS377, Milwaukee 48-39-0572 Portable Band Saw Blade – 3 Pack
27 in x 0.5 in x 0.02 in
18 TPI
Hook tooth profile
Bi-metal M42
3-pack
Pros
- Bi-metal M42 high speed steel resists heat and holds a weld
- Precision-sharpened teeth suit fine
- intricate cut shapes
- Fits both DeWalt compact saws and the Milwaukee M12 48-39-0572
- Three-pack format provides working spares
Cons
- 3-star share of 7% is the highest in this group
- so a noticeable group finds cut quality or durability only average
- The rating spread suggests inconsistency between individual blades inside a pack
Compact handheld saws use a much shorter loop than a full-size portable saw, and this 27 inch band is built for exactly that group. It fits the DeWalt DCS377, DCS377B, DCS375, and DCS375B, plus the Milwaukee 48-39-0572, which is the part number used by the M12 platform. If your saw is one of those, the geometry question is settled before you look at anything else.
The material is bi-metal M42 high speed steel, which is the general-purpose cobalt grade that forum users treat as the default for metal work. The tooth is an 18 TPI hook profile, precision-sharpened for fine, intricate cut shapes, and the stated cutting range runs from 5/32 inch to 3/16 inch on common material and 3/16 inch to 5/16 inch on very hard material. That is a sensible envelope for a sub-compact saw that most owners use on tube and trim.
Where this one diverges from the premium blades is in the rating spread. Seven percent of reviews sit at three stars and four percent at one star, the largest mid-tier cluster in the group, and the pattern points at variability between blades rather than a single fault. Reviewers with the largest bases note more variability in blade life than the DEWALT and LENOX options, so if you need predictable life over a production run, an OEM band is the safer bet.
For a homeowner or a contractor who cuts occasionally, though, that variability matters much less. Three blades in the box, sharp from the box, in a coil that fits your saw, is a solid combination for someone cutting a few times a month. The value case is strongest when the alternative is buying one blade at a time and running out mid-project.
Checking your compact saw before you order
Compact saw blade lengths are not interchangeable, and a mismatch shows up as a saw that will not tension or a blade that will not clear the guide. The four saw models named here cover a large share of the sub-compact market, and the Milwaukee part number is printed on the blade guard or the blade itself on OEM bands. Verify before you buy rather than after.
When to choose this over a full-size portable blade
Choose it if you own a DCS377, DCS375, or M12-class saw and your material runs from thin tube to about 5/16 inch solid. Choose something else if you regularly cut solid bar over a half inch, because an 18 TPI hook profile is a fine tooth for that job. It is also worth noting the 27 inch band is the shortest loop in this roundup, so it has the least material between the wheels and the least margin for a sloppy setup.
5. FOXBC 44-7/8 Inch 10/14 TPI Blade: The Widest Fitment List We Found
FOXBC 44-7/8 Inch Bandsaw Blades 10/14 TPI for Milwaukee 48-39-0551, DeWalt DCS374B Portable Band Saw, 44-7/8″ x 1/2″ x .020″, 3-Pack
44-7/8 in x 1/2 in x 0.020 in
10/14 TPI variable
Bi-metal M42 high speed steel
3-pack
Pros
- Fits the widest saw compatibility list of any 44-7/8 in blade here
- Bi-metal M42 high speed steel for heat resistance and weld strength
- Variable 10/14 TPI handles common and harder 3/16 in to 5/16 in material
- Three-pack balances cost and spares
Cons
- 5% one-star share suggests occasional dissatisfaction with cut life
- The 10 TPI end of the variable range is coarser than dedicated fine-tooth blades
Fitment is the number one real-world purchase blocker with portable band saw blades, so this blade’s compatibility list is its headline feature. The listed machines cover the Milwaukee M18 FUEL and corded models, the Bosch GCB10-5, several DeWalt models including the DCS374B, DCS376B, D28770, DWM120K, and DW328, the Makita XBP02Z, and the Wen 94396. For anyone who has owned more than one of these saws over the years, that is the whole 44-7/8 inch market in one pack.
The 10/14 TPI variable pitch sits at the coarse end compared with the rest of this list, and that is deliberate. The stated cutting range is 3/16 inch to 5/16 inch of material, and the coarse tooth is what gives the blade the gullet depth to move chips out of a heavy cut. Reviewers highlight the broad device compatibility and steady cutting on mid-thickness steel, with 80% of reviews at five stars.
The material is bi-metal M42 high speed steel, the same cobalt grade the premium OEM blades use, with heat resistance and weld strength cited in the technical data. In practice that means it behaves like a mid-grade OEM band rather than a bargain bin band, and the complaints are sparse enough that reviewers center them on blade life rather than fit, which is the opposite of what we would expect from a listing this broad.
There is a real trade-off at the coarse end. At 10 TPI the finish on thin material is rougher than a dedicated 18 or 24 TPI blade gives you, so if half your work is thin-wall tube, this is the wrong default. If your work is solid bar and structural section, it is exactly the right one.
Why 10/14 TPI suits thick solid bar
Coarse teeth mean deep gullets, and gullets are where chips go. On a heavy cut through solid bar, a fine-tooth blade fills its gullets before it clears the kerf, the tooth load climbs, and the edge breaks down. A 10 TPI end keeps the chip path open, which is why this blade and the 8/10 TPI option further down both target thick material rather than finishing work.
When this blade is the right buy
Buy it if you own a full-size 44-7/8 inch portable saw, cut structural material and solid bar as often as tube, and would rather not cross-reference part numbers. The 379-review base is solid and the fitment list removes the main source of returns. Pair it with a finer 18 TPI band if you alternate between thick and thin work weekly.
6. FOXBC 35-3/8 Inch 18 TPI Blade: Built Around the Milwaukee 2829-20
FOXBC 35-3/8 Inch Bandsaw Blade 18 TPI for Milwaukee 48-39-0529 Portable Band Saw Blade, 35-3/8″ x 1/2″ x .020″ 18 TPI, 3-Pack
35-3/8 in x 1/2 in x 0.020 in
18 TPI
Hook tooth profile
Bi-metal M42
3-pack
Pros
- Bi-metal M42 high speed steel with heat and weld resistance
- Hook tooth 18 TPI profile gives clean cuts on fine shapes
- Made specifically for the widely owned Milwaukee 2829-20 compact saw
- Three-pack provides usable spares
Cons
- 7% three-star and 5% one-star ratings point to more variability in blade life than the DEWALT and LENOX options
- Narrowly compatible with 35-3/8 in saws such as the 2829-20
The 2829-20 is one of the most widely owned cordless compact band saws in circulation, and this 35-3/8 inch band is made specifically for it, also matching part number 48-39-0529. The 1/2 inch width and 0.020 inch thickness are standard for this class of saw. If you own one of these, you will not find a better-matched coil.
The cutting characteristics are the same 18 TPI hook profile found on the 27 inch blade, in bi-metal M42 high speed steel with heat and weld resistance, and the teeth are precision-sharpened for fine, intricate cut shapes. In practice, on a compact saw, that combination gives a clean cut on tube and thin bar without the chatter you get from a coarse band in a tight loop.
Reviewers with 308 ratings report a good fit and solid cutting on the 2829-20 platform, with 78% of reviews at five stars. The rating spread runs a little wide, with 7% at three stars and 5% at one star, and the pattern again suggests more variability in blade life than the premium OEM bands. If you cut the same part hundreds of times, predictability is worth paying for. If you cut occasionally, this is a fine choice.
One structural note worth making: the compatibility is narrow by design. This is a 35-3/8 inch band, and if you later buy a full-size 44-7/8 inch portable saw, none of it carries over. Buying for the saw you own now, and adding a second coil for the saw you will own next, is the more economical path than trying to find one blade for two very different machines.
How this compares with the 8/10 TPI option for the same saw
Both bands fit the 35-3/8 inch footprint, and they solve different problems. The 18 TPI hook tooth here is a finishing-leaning band for tube, trim, and anything where the cut face matters. The 8/10 TPI Extreme Metal band later in this list is built for thick and extreme material, with fewer, deeper teeth that move chips faster on heavy cuts. Most owners of this saw end up with both.
Who should buy this 35-3/8 inch band
Buy it if you own a 2829-20 or an equivalent 35-3/8 inch compact saw and you cut tube, conduit, unistrut, and light bar on a cordless saw away from a bench. Skip it if your work is heavy solid metal every day, where the tooth count works against you. Check the length on your existing blade before ordering, because the 35-3/8 and 32-7/8 bands look similar in a drawer.
7. Makita A-97570 32-7/8 Inch 18 TPI Blade: The Long-Lived Single Blade
Makita A-97570 32-7/8″ 18TPI Compact Portable Band Saw Blade
32-7/8 in long
18 TPI
Wavy tooth set
Durable bi-metal build
Single blade
Pros
- Improved weld process extends blade life
- with users reporting they never broke one
- Wavy tooth set gives smooth
- precise cuts in sheets
- tubes and rod
- Bi-metal construction cuts mild steel
- cast iron
- stainless and non-ferrous metals
- Fits the Makita XBP01 and other 32-7/8 in saws
Cons
- Sold as a single blade
- so no spare is included
- A few users limit it to aluminum and want more evidence of long life on hard steel
The Makita’s differentiator is not the specification sheet, it is the weld. The technical data cites an improved welding process, and the user reports back it: owners say this blade outlives the OEM and aftermarket generic bands they replaced, and several mention never breaking one at all. On a handheld saw where the weld is the highest-stress point in the loop, that is where durability is actually won or lost.
The wavy tooth set is the other detail that shows up in user feedback. It gives smooth, precise cuts in sheets, tubes, and pipe, and the listed materials cover alloy steel, cast iron, metal, stainless steel, and cast steel. The 32-7/8 inch length fits the Makita 18V LXT XBP01, and several buyers note it also fits third-party saws of the same length, including some Ryobi models, which widens its usefulness considerably.
What 18 TPI buys you on a cordless compact saw
On a compact cordless saw, tooth count is a compromise between cut speed and finish, and 18 TPI sits closer to the finish end. The tooth is small enough to take a light bite, which means less stalling on a battery-powered saw and a smoother cut face on tube. It is the right pitch for sheet, thin wall, and precision trimming, and the wrong pitch for a full inch of solid bar. For straight lines in flat sheet stock, our guide to the best cordless track saws for sheet goods covers the other half of that job.
Should you accept the single-blade format
This one comes as a single blade, so there is no spare in the box. For an occasional cutter that is fine, and the lighter single-band format is easier to keep in a tool bag than a three-pack. For someone running a battery of cuts across a job site, a three-pack will save a trip when a tooth breaks at the wrong moment. Either way, the fitment and the weld quality carry the recommendation.
8. Milwaukee 48-39-0631 30-9/16 Inch 12/14 TPI Blade: Best for Stainless and Conduit
Milwaukee 48-39-0631 30-9/16″ 12/14 TPI Compact Extreme Thick Metal Band Saw Blade 3 Pack
30-9/16 in compact band
12/14 TPI variable pitch
Extreme thick metal
3-pack
Pros
- Highest average rating in this group at 4.7 with 87% five-star ratings
- Claimed 3X blade life in stainless steel and other extreme metals
- 2X faster cutting in thin metals and 25% more cuts per charge
- Optimized tooth design gives clean cuts on EMT
- conduit
- unistrut and rebar
Cons
- One reviewer received a blade with reversed teeth and another with an unlevel weld that made the saw jump
- A separate reviewer reported a blade lasting only about ten cuts
- A buyer returned it after the size did not match their saw
This is the highest-rated blade in the group, and the claims attached to it are specific rather than general. Milwaukee states 3X blade life in stainless steel and other extreme metals, 2X faster cutting in thin metals, and 25% more cuts per charge. The 30-9/16 inch band with 12/14 TPI variable pitch is aimed at the cordless compact platform, and the optimized tooth design is described as producing clean cuts on EMT, conduit, unistrut, and rebar. That is a field-service workload list, not a hobby list.
Stainless is the material that punishes cheap blades hardest. It work-hardens, it stays gummy, and it strips the teeth off a carbon steel band in a fraction of the time it takes to cut the same section in mild steel. Forum users report wasting money on carbon steel blades for stainless work, and this is the blade designed to avoid exactly that outcome. The variable pitch means one band handles thin conduit and heavier unistrut without a swap.
Be aware of one thing before you order: this is a compact-saw band, not a full-size portable blade. A buyer returned it after finding the length did not match their saw, and that is the single most avoidable return in this entire category. Measure your existing blade or read the part number before checkout.
The negative tail is worth reading too. At 4.7 with 87% five-star ratings, the complaints that exist are almost entirely manufacturing variation: one reviewer received a blade with reversed teeth, and another received one with an unlevel weld that made the saw jump, while a separate buyer reported a blade lasting only about ten cuts. If a fresh blade makes your saw jump, take it out and swap it rather than blaming your setup.
When a variable 12/14 TPI is the right stainless compromise
Stainless work at a field-service pace rarely sits at one thickness. You might be trimming EMT, then cutting a piece of angle, then rebar, all in the same hour. A variable 12/14 pitch lets the coarser 12 tooth sections carry the heavy sections and the finer 14 tooth sections clean up the thin ones, which is why this pattern has become common on compact saws aimed at trade work.
Who should buy this band and who should not
Buy it if you cut stainless, EMT, conduit, unistrut, or rebar on a cordless compact saw and you want the fewest blade changes. Do not buy it if you need a 44-7/8 inch loop, and check the three-pack for square welds and correct tooth direction on arrival. The performance claims are the strongest in this group, and the manufacturing consistency is the one variable you should verify yourself.
9. Oniguard 35-3/8 Inch 8/10 TPI Blade: The Choice for Thick Solid Bar
for Milwaukee 48-39-0609 35-3/8″ 8-10 TPI Extreme Thick Metal Bandsaw Blades 3PK
35-3/8 in x 1/2 in x 0.02 in
8/10 TPI variable
Extreme Metal bi-metal
3-pack
Pros
- Aggressive 8/10 TPI tooth design is aimed at thick and extreme metals
- Variable TPI so one blade covers a range of metal thicknesses
- Bi-metal construction for heat and wear resistance
- Listed for aluminum and soft alloys
- steel and steel alloys
Cons
- 6% one-star share is the second-highest in this group
- indicating some durability complaints
- The coarse 8 TPI end of the variable pitch is less suited to thin or intricate cuts
Eight teeth per inch is about as coarse as a portable band saw blade gets, and that is the entire point of this one. The aggressive tooth design is claimed to cut 2X faster in thick metals with 3X life in stainless steel and 25% more cuts per charge, and the variable TPI is described as a one-blade-for-all-thicknesses design. If your workload is solid bar, this is the tooth count that clears it.
The band is 35-3/8 inch long, 1/2 inch wide, and 0.020 inch thick, so it matches the same 2829-20-class platform as the 18 TPI option earlier in this list, and it fits any saw of that length. Construction is bi-metal in the Extreme Metal series, and the listed materials run from aluminum and soft alloys through steel and steel alloys, which covers the range where a coarse tooth actually earns its keep.
With 112 reviews, this is a smaller and newer listing than the others, and 84% of those reviews sit at five stars. Buyers who cut thick and extreme metal like the aggressive tooth and the variable approach. The visible caution is a 6% one-star share, the second-highest in this group, which points to some buyers wearing the blade out faster than they expected on a coarse tooth in a material that did not need one.
That is the predictable failure mode of an 8 TPI band, and it is a selection error rather than a quality problem. On thin or intricate work the teeth are too coarse to produce a clean face, the cut takes more force, and the tooth load climbs. If you are torn between this and the 18 TPI band for the same 35-3/8 inch saw, decide by material thickness first.
What coarse teeth gain and what they cost
A coarse tooth removes more material per pass, which is what makes a thick cut finish in reasonable time on a handheld saw. It also leaves a rougher kerf edge and a wider cut line, so on a visible surface or a precision notch it is the wrong choice. Most people who regret an 8/10 TPI blade regret using it on thin material, not on the thick material it was built for.
Who should buy this band
Buy it if you run a 35-3/8 inch compact saw and your cuts run thick: solid bar, square tube, heavy angle, and structural section. Pair it with the 18 TPI band for the same saw so the fine work stays clean. If your material is mostly thin wall, non-ferrous, or precision shapes, pick the finer pitch instead and skip this one.
10. DEWALT DW3986C 32-7/8 Inch 14/18 TPI Blade: The Flexible Middle Ground
DEWALT Portable Band Saw Blade, 32-7/8-Inch, .020-Inch, 14/18 TPI, 3-Pack (DW3986C)
32-7/8 in long
14/18 TPI variable pitch
Matrix II cobalt edge
8% cobalt
3-pack
Pros
- Same Matrix II cobalt high speed steel edge as the DW3983C
- Variable 14/18 TPI adapts to different material thicknesses
- Alloy steel backer resists fatigue under repeated cuts
- Large review base of 1484 ratings
- 3-pack format with working spares
Cons
- 6% three-star share suggests some users find it needs more blade changes on hard material
- Heavier per pack than a single compact band
- which adds bulk to a kit
This is the variable-pitch version of the DEWALT coil that tops this list, and it shares the same tooth metallurgy: Matrix II high speed steel, 8% cobalt content, Rc 65-67 hardness, and an alloy steel backer for fatigue resistance. The difference is the 14/18 TPI pitch, which spreads across thicker and thinner material than the fixed 18 TPI of the DW3983C. Same saw, same alloy, different tooth count.
With 1484 ratings and 79% of reviews at five stars, the volume of owner feedback here is close to the DW3983C’s, and it describes the same story: durability and clean cuts from the cobalt edge, with the recurring criticism that hard or thick material wears the blade faster than a fixed-pitch alternative tuned for heavy work. The alloy steel backer is the part that matters most on a handheld saw, because it is what keeps the loop from taking a set over repeated flexing.
The variable pitch earns its place on a mixed workload. The 14 tooth sections carry sections in the quarter-inch range and up, and the 18 tooth sections handle thinner material and a cleaner finish, so one blade covers a full day of mixed shop work without a swap. Reviewers consistently credit the durability and the cut quality, and the six percent three-star share centers on blade changes rather than breakage.
One practical note: at 159 grams per pack, three blades add bulk to a kit bag in a way a single compact band does not. On a handheld saw that is trivial. In a backpack for a lot of crawling through attics and crawlspaces, it is a small annoyance worth thinking about.
How to choose between the two DEWALT 32-7/8 inch blades
Both fit the same 32-7/8 inch saw and both use the same cobalt Matrix II edge. Pick the 18 TPI DW3983C if your material skews thin, because a finer tooth finishes cleaner and turns faster. Pick the 14/18 DW3986C if your material varies in thickness, because the variable pitch stops you from choosing wrong. If you already know your typical section size, the fixed-pitch blade is the more efficient pick.
Who should buy the DW3986C
Buy it if you run a 32-7/8 inch portable saw, cut a genuinely mixed workload, and want the cobalt edge with the flexibility of variable pitch. It is a sensible second coil for anyone who already owns the fixed 18 TPI and finds it lacking on thick material. It is less compelling if you cut one material type consistently, where a dedicated pitch will outlast it.
How to Choose a Portable Band Saw Blade for Metal Cutting
Choose your blade in a fixed order, because every step constrains the next one. Start with blade length, because no other specification matters if the loop does not fit your saw. From there, work through width, alloy grade, tooth pitch, and pack quantity, and you will land on a blade that fits the work instead of one that fits the drawer.
Step one: measure blade length before anything else
Portable band saw blades come in five widely used lengths in this category, and they are not interchangeable. The 27 inch band fits sub-compact DeWalt and M12-class saws. The 30-9/16 inch band fits a different class of cordless compact saw. The 32-7/8 inch band fits the Makita XBP01 and a range of 32-7/8 inch saws. The 35-3/8 inch band fits the Milwaukee 2829-20 platform. The 44-7/8 inch band is the full-size portable standard, used by M18 FUEL, Bosch, Makita, DeWalt, and Wen models. If you are still deciding which machine to buy, our picks in the portable band saw roundup start with the three lengths above.
Step two: confirm width and thickness
Nearly every metal-cutting portable blade in this group is 1/2 inch wide and 0.020 inch thick, which is the standard for this class of saw. Wider blades up to 3/4 inch exist for vertical bandsaws, not for handhelds. If a listing gives you a width other than 1/2 inch, it is not a portable saw blade.
Step three: pick an alloy grade by material
Cobalt bi-metal at roughly 8% cobalt content, in M42 or M51 grades, is the default for ferrous metal and the only sensible answer for stainless. Carbon steel costs less and cuts free-cutting mild steel adequately at reduced speed, but it strips teeth on hard alloys and dulls fast on abrasive work. Variable pitch reduces vibration and tooth loss compared with standard pitch, and it is worth paying a small premium for if you cut interrupted material.
Step four: match teeth per inch to section thickness
Coarse teeth for thick material, fine teeth for thin material, and a variable pitch if your thickness varies. A useful rule of thumb: if the section is thicker than 1/4 inch, you want 8 to 14 TPI. Between 1/16 inch and 1/4 inch, 14 to 18 TPI. Below 1/16 inch, 18 TPI and above. Each step up in TPI gives a finer finish and a slower cut.
Step five: decide between singles and packs
A three-pack lowers the per-blade cost and gives you a spare at the job site, which matters when a tooth breaks mid-cut. Forum users price-compare at the pack level, and the value of a spare is highest on compact saws you carry away from a bench. A five-pack makes sense if you run a full-size 44-7/8 inch saw several times a week. A single blade is reasonable for occasional use. Keeping a stable work surface matters too, and our miter saw stand picks cover the bench setup for cut-off work.
TPI Guide: Which Teeth Per Inch for Which Metal?
Teeth per inch is the single most searched number in portable band saw blades for metal cutting, and the most frequently misapplied. Higher TPI is not better in general. A finer tooth cuts slower and finishes smoother on thin material, and a coarser tooth cuts faster and holds up on thick material. Pick the pitch that matches the thickest material you regularly cut.
8 to 10 TPI: thick solid bar and heavy structural section
Use 8 to 10 TPI when you are cutting solid bar over a half inch, heavy square tube, or structural steel where cut speed matters more than finish. The deep gullets clear chips out of a heavy cut, which is what keeps the teeth from loading up. The finish is rough, and the cut line is wider, so keep this band away from visible trim work.
10 to 14 TPI: general purpose structural work
This is the most common pitch range in the field and the default for a shop that cuts angle, channel, I-beam, and medium bar. Fourteen TPI still holds an edge on hard material, and ten TPI moves material quickly. If you cut mostly structural steel and pipe, this is where you should live.
14 to 18 TPI: mild steel, tube, and mixed shop work
Fourteen to eighteen TPI is the middle of the range and the safest single answer for general metal cutting. It handles mild steel, stainless at moderate speed, tube, and unistrut, and it produces a noticeably cleaner face than a 10 TPI band. A variable 14/18 or 12/14 pitch lands in this same zone while covering a wider thickness range.
18 TPI and above: thin wall, sheet, and non-ferrous
Eighteen TPI and finer is for thin-wall tube, sheet metal, EMT, small solid bar, and non-ferrous materials such as aluminum, brass, and copper. Users report that bi-metal at 14 TPI or higher handles non-ferrous metals well, and that the finer tooth leaves a cleaner surface on soft alloys. Below about 1/16 inch, move to 24 TPI or higher.
Bi-Metal vs Carbon Steel vs Cobalt Blades: Which Material Wins?
A bi-metal band saw blade is a high-speed-steel tooth edge electron-beam welded to a flexible alloy steel backing strip, and for portable metal cutting it beats carbon steel in almost every category except purchase cost. A carbon steel blade is a single alloy that costs less, cuts free-cutting mild steel at a slower speed, and loses its temper quickly on hard alloys, abrasive material, or interrupted cuts. Cobalt high-speed steel, the M42 and M51 grades carrying roughly 8% cobalt, is the top tier inside the bi-metal group.
Carbon steel: cheap, fast on soft mild steel, fragile elsewhere
Carbon steel makes sense for one situation: occasional cuts through soft, free-cutting mild steel on a saw you barely use. It is a legitimate tool there. The problem is everything else. It dulls quickly, it strips teeth when you hit a hard spot, and it has almost no tolerance for the shock of an interrupted cut. Forum users report blades lasting a small number of linear feet with non-branded carbon steel bands, and the recurring frustration is wasted money on stainless work that a bi-metal blade handles without complaint.
Bi-metal: the correct default for portable metal cutting
A bi-metal blade welds a hard tooth edge to a springy backing, so the tooth can hold an Rc 65 to 67 hardness while the band survives being driven in reverse over a wheel on a handheld saw. That combination is why bi-metal dominates this list, and why the disagreement you will find online about bi-metal versus carbon steel is mostly about cost per cut rather than capability. Users on welding forums put it plainly: a quality bi-metal blade from a reputable brand, with the pitch then matched to the material size.
Cobalt M42 and M51: when hardness and heat resistance matter
M42 and M51 are the cobalt-bearing high-speed-steel grades at the top of the bi-metal range, and M42 is widely described as the best general-purpose metal-cutting grade. The roughly 8% cobalt content is what lets the tooth hold its temper in a heat-generating cut through hard or hardened material, and DEWALT publishes the figure on the two blades in this list. M51 pushes the same idea with added wear resistance for abrasive material. Neither is needed for soft mild steel, and both are the right call for stainless, hardened fasteners, and tool steel.
Portable Band Saw Blade Sizes and Saw Compatibility
Blade length is the one specification that cannot be worked around, and mismatched lengths are the top cause of returns in this category. Measure the loop on your existing blade, or read the OEM part number stamped on the blade guard, before you order. The five lengths below cover the overwhelming majority of portable band saws sold in 2026.
27 inch: sub-compact DeWalt and M12-class saws
The 27 inch band fits the DeWalt DCS377, DCS377B, DCS375, and DCS375B, and the Milwaukee 48-39-0572 part number used by the M12 platform. It is the shortest of the common portable loops and the most specialised.
30-9/16 inch: cordless compact extreme-metal saws
This is the compact band length used on the Milwaukee 48-39-0631, a variable 12/14 TPI coil designed for stainless, conduit, unistrut, and rebar. It is not interchangeable with the 32-7/8 inch band even though the difference is small.
32-7/8 inch: Makita XBP01 and 32-7/8 inch saws
The 32-7/8 inch band fits the Makita 18V LXT XBP01, and users report it also fits some Ryobi and other third-party saws of the same length. Two of the picks in this list use this length, in fixed 18 TPI and variable 14/18 TPI.
35-3/8 inch: the Milwaukee 2829-20 platform
The 35-3/8 inch band fits the Milwaukee 2829-20 and 48-39-0529, and it also fits any saw of that length. Two blades in this list share this footprint, in 18 TPI and in 8/10 TPI, so a single saw can be set up for both fine and coarse work.
44-7/8 inch: the full-size portable standard
The 44-7/8 inch band is the most common full-size portable length, and one pick here carries the broadest fitment list: Milwaukee M18 FUEL and corded models, Bosch GCB10-5, several DeWalt models including the DCS374B, DCS376B, D28770, DWM120K, and DW328, the Makita XBP02Z, and the Wen 94396. If you own any mainstream full-size portable band saw, this is almost certainly your length.
How to Set Cutting Speed and Read Your Chips
Cutting speed for a portable band saw is measured in surface feet per minute, and getting it roughly right does more for blade life than any product choice. The rule that circulates in the field is roughly 200 SFPM for a bi-metal blade and 100 to 125 SFPM for carbon steel, cited repeatedly on machining forums. Both figures are right for their own material, and the reconciliation is simple: a bi-metal tooth holds its hardness at temperature, a carbon steel tooth does not.
Break in a new blade before you judge it
Run a new blade at reduced speed for the first several feet of cut. The tooth is freshly ground and the backing is under new tension, and a hard first cut at full speed is where new blades fail. A slower break-in pass lets the teeth settle, the pitch take its set, and the weld stabilize before you put real load on it. It costs a few seconds and it is the cheapest blade-life extension available.
Read the chips, then change your feed
Chip colour and shape tell you what the cut is doing. Powdery chips mean you are feeding too lightly, so the tooth is rubbing rather than cutting, which dulls the edge and generates heat. Blue or burned chips mean you are feeding too hard or moving too slowly, so friction is generating heat the tooth cannot shed. Loosely curled chips, the target, mean the tooth is cutting properly and the feed is right. Adjust the downward pressure until the chip curls rather than powders or burns.
Drift and wandering are usually technique, not the blade
Users on metalworking and woodworking forums describe blade drift on cordless compact saws as a persistent annoyance, especially on thicker material. In most cases the cause is the operator pressing into the workpiece at the start of the cut instead of letting the saw pull itself through. Set the tooth on the surface, release the pressure, and let the machine do the work. If the blade still tracks off line, check that the teeth point in the direction of travel and that the band is running square on the wheels.
Breaks at the weld and how to reduce them
Blades snapping at or near the weld are one of the most common complaints in the forums, with users reporting repeated wobbles at the weld across multiple bands on the same saw. A few habits reduce it. Do not start a cut at full speed. Do not back the saw out of a cut under load. Keep the band correctly tensioned, because an over-tensioned blade fatigues the weld faster. And when a break does happen at the weld, run your hand along the band before reinstalling it, because a nick in the backing will travel to the next failure point.
Use cutting fluid. On ferrous material it carries heat away from the tooth, clears chips out of the gullet, and leaves a cleaner cut face. A dry cut on stainless is the fastest route to a blue chip colour and a dull edge.
Frequently Asked Questions
What type of band saw blade is best for cutting metal?
A cobalt bi-metal blade with a high-speed-steel tooth edge, such as an M42 or M51 grade, is the best type for cutting metal on a portable band saw. The tooth edge is welded to a flexible alloy steel backing so it survives the reverse bend of a handheld saw, and the roughly 8% cobalt content lets the tooth hold its temper in a heat-generating cut. Pair it with a pitch that matches your thickest material: 10/14 TPI for structural work, 14/18 TPI for general shop work, and 18 TPI or finer for thin wall and non-ferrous metals.
Is 18 or 24 TPI better for metal?
It depends entirely on section thickness, not on the material name. 18 TPI is the better choice for most portable metal cutting because it handles anything from thin-wall tube up to roughly a quarter inch of solid material, and it still cuts smoothly and relatively quickly. 24 TPI gives a cleaner finish on very thin wall, sheet, and non-ferrous material, but it is slower and strips teeth faster on thick or hard material. If your material is 1/8 inch or thicker, 18 TPI is the right answer.
What are the differences between carbon steel and bi-metal bandsaw blades?
A carbon steel blade is a single alloy that costs less, cuts free-cutting mild steel at roughly 100 to 125 SFPM, and loses its temper quickly on hard alloys, abrasive material, or interrupted cuts. A bi-metal blade welds a hardened high-speed-steel tooth edge to a flexible alloy steel backing, so the tooth can run at roughly 200 SFPM while the band still flexes on a handheld saw. In practice bi-metal lasts several times longer on steel, is the only sensible choice for stainless, and is the default for portable metal cutting.
Can I put a metal cutting blade on my bandsaw?
Only if the blade length matches your saw exactly. Portable band saw blades come in several non-interchangeable lengths, including 27 inch, 30-9/16 inch, 32-7/8 inch, 35-3/8 inch, and 44-7/8 inch, and almost all of them are 1/2 inch wide by 0.020 inch thick. Metal-cutting blades also have a rigid tooth set and gullets sized for chip evacuation, so they are not a substitute for a wood blade. Measure your existing loop or read the OEM part number before ordering.
What is the best TPI range for a bandsaw blade?
For metal cutting on a portable band saw, 10 to 18 TPI covers the useful range. Use 8 to 10 TPI for solid bar over a half inch and heavy structural section, 10 to 14 TPI for general structural steel and pipe, 14 to 18 TPI for mild steel, tube, and mixed shop work, and 18 TPI or higher for thin wall, sheet, and non-ferrous metals such as aluminum, brass, and copper. A variable pitch such as 10/14 or 14/18 covers a wide thickness range with one blade.
Conclusion: Our Picks for Portable Band Saw Blades for Metal Cutting
The DEWALT DW3983C takes our top spot for portable band saw blades for metal cutting because nothing else in this group combines a cobalt Matrix II edge, a 32-7/8 inch and 44-7/8 inch footprint, and 5140 owner ratings behind it. The LENOX 44-7/8 inch Tuff Tooth five-pack is the pick for a full-size saw running mostly on steel, and the Morse Master Cobalt 14/18 is the one to buy when you want a single variable-pitch band that covers mild steel, stainless, and aluminum.
Beyond those three, match the length to your saw first, then match the pitch to your thickest material, and only then look at the alloy grade. The remaining seven picks cover the sub-compact, cordless, and extreme-metal platforms, and the chip-reading and break-in habits above will extend the life of whichever one you load. If you are still choosing the machine itself, start with our guide to the best portable band saws for metal cutting and pick a coil to match it.
