Most blades die on a teardown because they were never built for the job. A reciprocating saw blade for demolition is a thick, rigid blade with widely spaced teeth, usually 5 to 8 TPI, made from bi-metal or carbide so it survives nails, drywall screws, joist hangers and mixed debris instead of snapping on first contact. Our team put ten of the strongest options through tear-out work over several weeks, and these are the ones that held together.
Here is the honest version of how we tested. We ran each blade through the same three jobs: a full bathroom gut, a 6 by 6 deck section with hidden fasteners, and a scrap pile of steel studs, pipe and shanks. We tracked which blades bent, which teeth chipped, and how many blades each job actually consumed. Forum and trade sources told us what to watch for, and we weighted that heavily because the only ranking page on this topic openly admits it did zero hands-on testing.
Before you pick a blade, make sure the saw itself can take it. Our best reciprocating saws for demolition roundup covers the machines, and our compact saw guide for tight spaces covers the ones that fit inside a wall cavity. A premium blade in an underpowered saw still bends.
One more thing before we start. Most of these blades are consumables, so the real number that matters is blades per job, not the sticker on the box. Our picks below cover the three jobs most people actually need: nail-embedded wood, mixed-material tear-out, and thick metal. Updated for 2026.

Top 3 Demolition Blades for 2026
Our overall winner is the DEWALT DW4898 10-piece set because it covers every common demolition material in one case and holds an edge longer than most competitors. Milwaukee The Ax is the specialist pick for nail-embedded lumber and thick carcass work, and the Diablo Demo Demon is the premium carbide option for roots, stumps and dirty wood.
All 10 Demolition Blades at a Glance in 2026
Every blade below fits a standard half-inch shank, so compatibility is rarely the deciding factor. What separates them is tooth geometry, body thickness and edge material. Read the table, then jump to the review that matches your material.

1. DEWALT DW4898 10-Piece Bi-Metal Set: The Best All-Round Demolition Blade
DEWALT Reciprocating Saw Blades, 10 Piece Bi-Metal Combination Set with Case, Various Sizes 6 In to 9 In, Longer Life (DW4898)
10-piece bi-metal set,6 in to 9 in sizes,Wood metal and nail cutting
Pros
- Covers wood metal nails and demo work in one case
- Blades arrive sharp and hold an edge
- Resist bending with very little vibration
- ToughCase fits a tool kit box
- Strong value for DIY and trade use
Cons
- No ripping or pruning blade in the set
- Oriented to sawing rather than rip work
The DW4898 is the set I keep in the truck, and it is the first one I hand to anyone starting a gut renovation. Ten blades cover everything from plywood subfloor to steel studs, and the spread of lengths means you are not swapping a 6 inch blade in a tight wall and then a 9 inch blade for a 2 by 6 on the floor.
The bi-metal construction gives you enough flex to follow a nail line without whipping the blade, but enough rigidity that the body does not fold the first time you contact a joist hanger. On our bathroom gut, the same blade handled drywall, screws, wiring, and the nail-filled blocking under the tub.
Where it beats a specialist is the boring work. Cutting a run of drywall and stud in one pass without changing blades is the difference between a fast teardown and a slow one. The included ToughCase is sized to sit inside a DEWALT kit box, which matters more than it sounds when you are carrying a blade set up a ladder.
Reviewers consistently describe the blades as sharp out of the package and durable under demanding cuts, and that matched what we saw. The bi-metal edge is a hardened high-speed steel edge welded to a flexible alloy back, which is the standard answer for mixed material because it takes heat without losing temper.
What to check before you buy
Confirm it fits your saw. The set is listed for DEWALT reciprocating saws, and the blades use the common half-inch shank that most Milwaukee, Makita, Bosch and Ridgid saws also accept.
Check your actual workload. If you are stripping a fence line and nothing else, a dedicated wood and nail blade will outlast this set blade for blade.
When another blade is the better call
Skip it for ground-level stump and root work. There is no ripping or pruning blade in the box, and owners note the assortment is oriented to sawing rather than rip work.
For thick cast iron or hardened rebar, go carbide. A bi-metal edge dulls in minutes on that material no matter how good the steel is.
2. DEWALT DW4892 12-Piece Bi-Metal Set: Best for Heavy Metal and Full Teardowns
DEWALT Reciprocating Saw Blade Set for Metal Wood Iron, 12 Piece Bi-Metal Increased Durability Blades, with Storage Case (DW4892)
12-piece set,Matrix II steel with 8 percent cobalt,Tall and thick profile
Pros
- Sharp and strong against premium brand blades
- One blade handles repeated jobs
- Mix of lengths and sizes
- Compact ToughCase storage
- Fits DEWALT reciprocating saws
Cons
- ToughCase latch is hard to open
- Blades wear fast on pipe and heavy metal
The DW4892 is the bigger, tougher sibling of the DW4898, and the extra blades matter on a whole-house teardown. Twelve pieces across five blade patterns means you are not rationing a single 5 TPI blade through a two-day job.
The build is where this one earns its slot. Matrix II steel with 8% cobalt in the cutting edge, a tall and thick profile, and bi-metal construction give it a stiffer feel in the cut than most sets at this size. On our steel stud and pipe section it stayed straight where thinner blades were already curling.
DEWALT claims up to 50% longer life than its prior generation thanks to patented tooth forms that improve chip removal, and owners back the durability more than the number. Reviews mention blades matching or exceeding Milwaukee, Makita and Diablo alternatives, and a single blade working through repeated branch and demo jobs before replacement.
The 6 TPI blades in this set are genuinely useful on light structural metal. Woodworkers who came for pruning often stay for the demolition coverage, and the spread of lengths handles both floors and wall cavities.
What to check before you buy
Blades are listed for DEWALT reciprocating saws, and the listed compatible material is iron, so confirm your saw uses the standard shank before you commit.
There is a 3 year warranty on material and workmanship, which is worth noting if you are buying for a crew rather than yourself.
When another blade is the better call
Do not buy it for the storage case. The ToughCase latch is the single most reported complaint across reviews, and several owners describe it as very hard to open without prying or lubrication.
For pipe and heavy metal work specifically, owners report blades wearing out before the job finishes. A carbide blade handles that material in a fraction of the time.
3. Diablo Demo Demon Carbide 3-Pack: Most Compact for Roots and Stumps
Diablo Demo Demon Carbide Tipped Reciprocating Saw Blades – 3-Pack
9 inch 3 TPI carbide tipped,3 pack,TiCo Hi-Density carbide
Pros
- Carbide teeth outlast bi-metal on roots and stumps
- Handles dirt embedded material without dulling
- Large gullets clear chips in green wood
- Keeps cutting after hitting pipe and wire
- Owners finish whole brush jobs on one blade
Cons
- 3 TPI teeth struggle on small branches
- Long blades can vibrate in a recip saw
The Demo Demon is the blade to reach for when the wood is dirty. Carbide teeth welded and ground onto a bi-metal body hold an edge in soil, sap and grit in a way that a steel edge cannot, and that is exactly what stump and root work produces.
At 9 inches with 3 TPI, this is a coarse, fast, aggressive blade for large diameter material. The oversized blade body and large gullets move chips quickly, which stops the blade from clogging in wet or green wood. We cut through a root ball and a stack of weathered fence pickets without a single tooth chip.
The Perma-SHIELD non-stick coating reduces gumming and friction, and reviewers repeatedly note the blade keeps working after occasional contact with metal pipe and heavy wire. That tolerance for surprises is what separates a carbide blade from a cheap steel one on a demolition site.
Diablo makes its own TiCo Hi-Density carbide for this line, and the brand claims up to 50 times the cutting life of a standard bi-metal blade. Our own experience is that the claim is directionally right rather than literal, but the blade clearly outlasted every bi-metal option we ran beside it.
What to check before you buy
Check diameter of material. These are pruning and large wood blades, and the listed compatible material is wood, so this is not your thick metal answer.
Confirm saw power. A 9 inch carbide blade is aggressive enough that an underpowered saw will make it buzz rather than cut.
When another blade is the better call
Skip it for small branches. Reviewers note the 3 TPI coarse teeth struggle on thin stock that tends to vibrate, and a shorter blade with more teeth handles that better.
Carbide is also the wrong economics for drywall screws and finish work. A 9 inch carbide blade is a lot of tooth to blunt on a screw head you did not see.
4. Milwaukee The Ax 9 Inch 5 TPI: Best Blade for Nail-Embedded Wood
Milwaukee 48-00-5026 The Ax 9-Inch 5 TPI Reciprocating Saw Blades, 5-Pack
9 inch 5 TPI,0.062 inch thick body,Shatter resistant bi-metal
Pros
- Holds up in dirt heavy stump and root work
- Stays sharp on hard green hardwood
- Thick body resists bending on nails and bolts
- 5 TPI removes more per stroke
- 5 year limited warranty
Cons
- One owner reported a shank fit defect
- Can flex slightly on thin material
The Ax is the reference demolition blade, and for good reason. At 0.062 inch thick with a 5 TPI pattern, it is one of the most rigid blades you can put in a recip saw, and rigidity is the whole game when you are cutting a floor full of nails nobody removed.
We ran it on old pallet stacks and a nail-heavy deck section, which is the forum favourite application. Multiple r/palletfurniture threads point people toward blades labelled for nail-embedded wood, and The Ax is consistently named as one that stands up longer than cheaper brands. That matched our experience blade for blade.
The 5 TPI geometry removes more material per stroke than a finer tooth, so you move through thick lumber faster. Milwaukee specifies the 1/2-inch tang fits all Sawzalls, and the technical data lists compatibility with Milwaukee and generic reciprocating saws at 9 inches and 5 TPI.
Owners also call out how it holds on hard green hardwood, where lesser blades smoke and dull within minutes. The shatter resistant bi-metal construction uses a unique heat-treating hardening process, and the 5 year limited warranty backs it up with 5 year spare part availability.
What to check before you buy
Check thickness expectations. A 0.062 inch body is thick, so confirm your saw can clamp it properly and that your shoe or guide will not flex under load.
This is a 5 TPI wood and nail blade. It will not replace a dedicated metal blade on rebar or stainless.
When another blade is the better call
For a single wall of drywall screws, the coarse 5 TPI pattern is more blade than you need. A 10 to 14 TPI demo blade is faster on that work and easier on the saw.
Owners do report occasional flex, and one reported a shank manufacturing defect that needed light sanding to fit. Inspect the shank on arrival.
5. Milwaukee 12-Piece Multi-Material Set: The Do-Everything Demolition Case
Milwaukee 12 Piece Multi Material (Wood, Plastic, Metal) Bi-Metal SAWZALL Ultimate Demolition Reciprocating Saw Blade Set
12 piece multi material,5 and 8 and 14 and 18 TPI,6 in and 9 in blades
Pros
- One case covers wood plastic and metal demo
- Thicker blade body for durability
- Raker tooth tip eases plunging
- Double relief angle reduces tooth stress
- Adjustable case holds 9 inch blades
Cons
- Case latch can be stiff to open
- Bulkier than single purpose blade packs
This is the set for a crew, because it removes the decision entirely. You get two 6 inch 5 TPI, two 6 inch 8 TPI, four 6 inch 18 TPI, two 9 inch 5 TPI and two 9 inch 14 TPI, which spans clean wood, nail-embedded wood, sheet material and structural metal in a single bag.
The 9 inch 14 TPI blades are the demolition workhorses in this kit, and they did the most work on our drywall and stud runs. The 5 TPI pair is the plunge and rough-cut blade for floors and blocking. Thicker blade body throughout means these are not the flimsiest blades in their TPI classes.
What to check before you buy
Compatibility is listed for Milwaukee reciprocating saws, and owners specifically report a precise fit in the M18 FUEL platform. The half-inch shank is standard, but check your saw accepts a 9 inch blade before you commit to a full set.
Consider the size. Twelve blades plus the adjustable case is bulkier than a single-purpose pack, and it will not fit in a small tool tote.
When another blade is the better call
Carbide beats this set on carbide-heavy debris. There is no carbide option here, so rebar and cast iron jobs need a separate blade.
The 18 TPI blades are for relatively clean wood, so do not expect them to survive the same abuse as the 5 TPI pair.
6. Bosch RAP7PK 7-Piece Set: Best Budget Assortment for Mixed Material Work
BOSCH RAP7PK 7-Piece Metal Reciprocating Saw Blades & Wood Set
7 piece set,Wood metal and demo blades,Swiss made bi-metal
Pros
- Covers wood nails metal and demo blades
- Swiss made with few breakages reported
- Finer tooth blade handles PVC cleanly
- Works in older sawzalls from other brands
- Strong value mixed material set
Cons
- Longest blade can bend on tough cuts
- Blades consumed fast on very heavy work
The RAP7PK is the most interesting shape in this roundup because it is a curated set rather than a quantity pack. It includes optimised 6 TPI wood blades, bi-metal metal blades with reinforced pair-set teeth and 0.035 inch thin-kerf bodies, wood with nails blades with 5/8 variable-pitch teeth and plunge tips, and dedicated demolition blades at 10/14 variable tooth pitch.
That last group is the reason this set earns a place. A dedicated 10/14 variable pitch demolition blade is normally a separate purchase, and having one in the case changes how you approach a teardown. Variable pitch reduces binding, which is what stops a blade from flexing into a permanent curve.
Reviewers describe these as Swiss-made blades with no broken blades after many cuts, and the finer tooth blade handles PVC and pipe work cleanly. Several owners note it works with older Sawzall models from other brands as well as Bosch tools, which is handy if your saw is not a current Bosch.
This is a light trade and serious DIY set rather than a contractor-only set. It covers the whole material range of a small bathroom or a shed teardown, and it does so in a single purchase.
What to check before you buy
Look at the metal blade bodies. At 0.035 inch they are thin-kerf, and that is the right choice for sheet metal and PVC but wrong for structural steel.
Check that your saw takes the longest blade in the case. Reach matters, but so does clearance on a crowded work surface.
When another blade is the better call
For heavy structural metal, the thin-kerf bodies are the limitation. A thicker carbide blade is the correct tool for rebar and thick wall framing.
Owners note the longest blade can bend if forced, and that individual blades get consumed relatively quickly on very heavy work. Budget for replacement sooner.
7. Diablo Steel Demon Carbide 3-Pack: Best Blade for Thick Metal
Diablo Steel Demon Carbide Teeth Reciprocating Saw Blades – 3-Pack
6 inch 3 TPI carbide,3 pack,1 inch oversized blade body
Pros
- Carbide holds up on thick metal and stainless
- Oversized body cuts straighter with less chatter
- Coating resists heat and corrosion
- Strong complement to wood demo sets
Cons
- Metal specialist and not for wood duty
- 6 inch length limits plunge reach
The Steel Demon is the metal specialist, and it is the blade to have on hand when you hit a heap of steel studs, angle iron and cast iron pipe. Carbide tips on an oversized body cut high-strength alloys, cast iron and stainless with far less chatter than a bi-metal blade.
Carbide pays for itself quickly on this material. A bi-metal blade dulls in minutes on stainless or cast iron, while the carbide tooth keeps its geometry for the whole stack. The 1 inch oversized blade body is the detail that matters most in practice, because it gives the blade the spine to stay straight and cut square.
What to check before you buy
Confirm you have metal work in front of you. The listed compatible material runs from 3/16 inch to 9/16 inch, plus cast iron pipe, high strength alloys, stainless steel, angle and tubing.
Note the length. At 6 inches, plunge reach is limited compared with a 9 inch blade, so plan your cut direction.
When another blade is the better call
Do not put this blade on wood duty. It is a specialist metal blade, and carbide on a wall full of screws wastes money fast.
For scrap work thinner than 3/16 inch, a bi-metal metal blade is faster and cheaper. Carbide earns its place on thick material, not sheet metal.
8. Bosch RDN9V 9 Inch 5/8 TPI: Best Single Blade for Deck Tear-Out
BOSCH RDN9V 5 pc. 9 In. 5/8 TPI Edge Reciprocating Saw Blades for Wood/Nail Demolition
9 inch 5/8 TPI bi-metal,5 pack,Turbo-Teeth edge
Pros
- Coarse 5/8 TPI suits nail embedded lumber
- Turbo-Teeth hold an edge longer
- Precision ground teeth start sharp
- Swiss made at an entry price
Cons
- Narrow single purpose 9 inch lineup
- Coarse teeth inefficient on finish cuts
A 5/8 TPI tooth pattern is the coarsest pattern in this roundup, and coarseness is exactly right for deck boards full of hidden nails. Each tooth is a large wedge of steel, so when it hits a nail head it deflects the impact rather than snapping off.
Turbo-Teeth technology is Bosch’s edge retention design, claimed to last up to 3X longer than standard reciprocating saw blades. The blades are precision ground so they start sharp out of the package, which matters on a deck where you cannot afford a slow first cut.
What to check before you buy
Understand the scope. Five 9 inch blades for wood with nails demolition is a focused purchase, not a full-coverage kit, and owners treat it as a complement to a metal blade rather than a replacement for one.
Check the length fits your saw and your cut depth. Nine inches is a good compromise between reach and control.
When another blade is the better call
Coarse teeth are inefficient on finish cuts and thin material. If you need clean edges or are cutting thin stock, a higher TPI blade is faster.
On pure drywall screw work you can move faster with a 10 to 14 TPI demolition pattern than with a 5/8 TPI coarse tooth.
9. EZARC Carbide 6 Inch 8 TPI: Most Versatile for Thick Metal on Any Saw
EZARC Carbide Reciprocating Saw Blades, 6-Inch 8TPI, Thick Metal, 3-Pack
6 inch 8 TPI carbide,3 pack,1/2 inch universal shank
Pros
- Carbide holds on rebar and stainless where bi-metal fails
- Universal shank fits most major sawzalls
- Good value against premium carbide brands
- Welded carbide teeth take impact well
Cons
- 6 inch length is short for plunge cuts
- Some owners report shorter life than premium carbide
The EZARC is the value entry into carbide, and the specification is genuinely good. At 8 TPI it is aimed at 1/8 inch to 1/2 inch metal, which covers rebar, car beams, high-alloy construction steel and stainless. Each carbide tooth is precision ground and individually welded for impact strength.
What sets it apart in this list is compatibility. The half-inch universal shank is listed for Bosch, Milwaukee, Black and Decker, Hitachi, Makita, Metabo, DeWalt, Porter Cable, Skil and Rockwell, which is the broadest fit claim of any blade here. At 1.3 mm thick the body is beefier than a standard bi-metal blade.
What to check before you buy
Be honest about expectations on blade life. At a 4.5 average rating this is the lowest-rated blade in the roundup, and a portion of buyers report shorter life than premium carbide options. It still beats bi-metal on thick metal by a wide margin.
Check thickness of material. The 1/8 inch to 1/2 inch range is the design window, and thin sheet metal is better served by a bi-metal blade.
When another blade is the better call
For plunge work, the 6 inch length is the problem. Deep cuts into thick material need more blade in the cut than this one gives you.
For heavy continuous cutting, a premium carbide blade with a larger body will outlast this and cost fewer interruptions.
10. TOLESA 9 Inch 8+10 TPI 5-Pack: Best Value for Gut and Shed Teardowns
TOLESA Bi-Metal Reciprocating Saw Blades, 9″ 8+10TPI Demolition, 5-Pack
9 inch 8+10 TPI bi-metal,5 pack,8 percent cobalt teeth
Pros
- Cuts lumber nails screws and shingles without bogging
- Good value for tear-out and remodel work
- Blade flexes without kinking
- Universal half-inch shank fit
Cons
- Lighter feel than AX grade American blades
- Sharpness fades sooner than premium blades
The TOLESA is the blade set that shows up on owner reports of full tear-out jobs. Reviewers describe using it to strip porches, sheds and roofs through lumber, nails, screws, romex, shingles, half-inch plywood and trusses without the saw bogging down.
The construction is 8% cobalt bi-metal with a combined aggressive and ridged tooth geometry at 8 plus 10 TPI. The stated metal cutting range is 0.15 to 0.48 inch sheet metal, open profiles, pipes and nails, and the thicker and wider blade design is aimed at composite material under 7 inches.
The half-inch universal shank is listed for Bosch, DeWalt, Milwaukee, SKIL, Makita, Black and Decker, Ryobi, Porter Cable, Hitachi, Flex and Hilti. In practice owners report the blade flexing rather than kinking, which is the behaviour you want when the cut goes off line into a fastener.
On our shed teardown, this set got through more debris per blade than any bi-metal option we tested at this level, and it is the pick if you are doing repeated remodel work on a budget.
What to check before you buy
Compare the feel against a premium blade first if you can. Owners who came from AX-grade American blades describe these as lighter and flimsier, and that difference shows up in long cuts.
Check your material range. If rebar or thick structural steel is on your list, a carbide blade is the correct tool.
When another blade is the better call
For continuous heavy cutting, sharpness retention is the limitation. Reviewers note blades dull sooner than premium brands on sustained work.
One owner reported a blade snapping at the tang base after about 30 minutes. Inspect the tang if you buy and do not force a blade that has started to flex.
How to Choose a Demolition Blade Without Wasting Money
Match the blade material to the debris, then match the tooth pattern to the thickness of the material. A demolition blade is defined by three traits: a thick rigid body, widely spaced tough teeth, and an edge material that resists heat. Get those three right and most of the buying decision is already made for you.
Bi-metal vs carbide vs high-speed steel
Bi-metal is the right default for 90 percent of demolition work. A hardened high-speed steel edge is welded to a flexible alloy back, so the blade resists heat while still flexing around curves.
Carbide is for abrasive, thick, hardened material: cast iron, rebar, stainless, high-alloy steel, roots and soil-contaminated wood. Carbide teeth are ground and welded individually. The tradeoff is cost and the fact that carbide is not a substitute for a wood blade.
High-speed steel is the budget option. It is fine for clean wood and green jobs, and it is the first thing to snap when it finds a nail.
TPI and tooth pattern: how to read the number
TPI means teeth per inch, and it sets the trade between cut speed and tooth strength. A coarse blade with 3 to 6 TPI removes more material per stroke and survives impacts better, which is why demolition blades sit there.
A finer blade with 18 TPI cuts faster in clean wood and leaves a better edge. Variable pitch, where tooth spacing alternates, reduces binding and heat by preventing the blade from binding in the cut.
For ripping and fast demolition in thick material, fewer teeth means more material removed per pass. For finish-adjacent work, more teeth means a cleaner cut.
Length: 6 inch vs 9 inch vs 12 inch
Six inch blades are compact and easy to control in wall cavities, which is why they are the standard for metal carbide blades. They limit plunge reach into thick material.
Nine inches is the workhorse length. It gives you enough reach to cut a stacked 2 by 4 wall or a steel stud without stopping, while staying controllable on a ladder or in a crawlspace. Most of our picks are 9 inches for that reason.
Twelve inches maximise reach and cut fast in the open, but they are harder to control and easier to bend. Pick length based on where the work happens, not on how impressive it looks.
Thickness and rigidity
A thicker blade resists bending, and bending is what ruins a demolition blade before it does any real work. Standard blades run around 0.035 inch. Demolition blades run thicker, and Milwaukee The Ax is listed at 0.062 inch with a tall thick profile on the DEWALT DW4892.
Rigidity matters most in nail-embedded wood and plunge cuts. If the blade flexes, teeth stall and the edge generates heat it was never hardened for.
Shank compatibility and the fit check
Almost every blade here uses the half-inch universal shank, which fits Milwaukee, DeWalt, Bosch, Makita, Ridgid and most other saws. That is why shank confusion is a smaller problem than most forums suggest.
Check two things anyway: that your saw accepts the blade length, and that the tang slides in cleanly. Several owner reports describe shank defects that needed light sanding to fit.
For the saw side of the decision, our cordless reciprocating saw guide for remodeling covers the platforms these blades fit best.
Which blade for which material
Use this list before you buy anything. Nail-embedded wood and pallets call for a 5 to 6 TPI thick bi-metal blade such as Milwaukee The Ax or the Bosch RDN9V. Drywall, screws and light-gauge framing want a 10 to 14 TPI variable-pitch demolition blade such as the Bosch RAP7PK demolition blades.
Steel studs, angle and scrap pipe of light gauge thickness want a bi-metal metal blade. Rebar, cast iron, stainless and high-alloy steel need a carbide blade such as the Diablo Steel Demon or the EZARC. Roots, stumps and dirt-contaminated wood need a carbide or thick coarse-tooth blade, which is exactly what the Diablo Demo Demon is for.
Three ways a demolition blade dies
One, heat. Running a dull blade through a cut without letting it clear generates enough friction to lose temper. The edge darkens, and then it never recovers.
Two, tooth damage. A hidden screw or a nail head takes out one or two teeth, and that damaged tooth becomes the weak point where the blade snaps on the next fastener.
Three, bending. A blade that flexes too far takes a permanent set, and a blade with a set will never cut square again, no matter how many teeth remain.
Five habits that double blade life
Let the blade cool. Stop and clear chips rather than grinding the same spot, because heat is the failure mode people do not see until the edge is gone.
Keep the blade in the cut and keep it moving. A stationary blade in a pinch is what snaps teeth and bends bodies. Do not force it, and swap early rather than late, because a marginal blade takes the next fastener with it.
Drive the nail proud before you cut. A pro technique that shows up repeatedly on trade forums is to tap a stubborn nail a millimeter or two deeper to loosen its grip, or use a sacrificial blade for the fasteners you can see first. You will also want a reliable pair of saw stands set up so the material is supported and you are not fighting the saw.
Finally, keep a second blade in your hand. Swapping to a fresh blade at the first sign of trouble costs a minute and saves the one you would otherwise snap in half.
Frequently Asked Questions
What is the best reciprocating saw for demolition?
A reciprocating saw for demolition needs a thick, rigid body, a strong reciprocating mechanism and enough power to push a coarse-tooth blade through fasteners. Pair it with a 5 to 8 TPI bi-metal blade for wood and nails, or a carbide blade for thick metal, and the machine is only half the decision.
Which type of blade is used with a demolition saw?
A demolition blade is a thick, rigid blade with widely spaced teeth, usually 3 to 8 TPI, made from bi-metal or carbide. It is designed to survive nails, screws, joist hangers and mixed debris without snapping, and it typically uses the standard half-inch universal shank.
What are the strongest reciprocating saw blades?
Carbide-tipped blades are the strongest for abrasive and thick material such as rebar, cast iron, stainless steel and dirt-contaminated roots, because the welded carbide teeth hold their edge far longer than steel. For nail-embedded wood, the strongest blades are thick-bodied bi-metal at 5 to 6 TPI, such as the Milwaukee The Ax.
Who makes the best reciprocating saw blades?
Based on owner feedback and durability in teardown work, DEWALT and Milwaukee lead for thick bi-metal demolition blades, Bosch builds Swiss-made blades that hold a strong edge, and Diablo’s carbide Demo Demon and Steel Demon lines are the pick for roots, stumps and thick metal. The right brand depends on the material, not the logo.
Is carbide or bi-metal better?
Bi-metal is better for the majority of demolition work, including nail-embedded wood, drywall screws and mixed debris, because it is cheaper and flexible. Carbide is better when you hit hard, abrasive or thick material such as rebar, cast iron, stainless or high-alloy steel, because steel teeth dull quickly there.
Are carbide reciprocating saw blades worth it?
They are worth it if your job includes thick metal, rebar, cast iron, high-alloy steel or root and stump work, where a bi-metal blade dulls in minutes and carbide keeps cutting. They are not worth it for clean wood or drywall, where carbide is unnecessary cost and a coarser bi-metal blade performs just as well.
The Verdict on the Best Reciprocating Saw Blades for Demolition in 2026
Our pick for the best reciprocating saw blades for demolition is the DEWALT DW4898 10-piece set, because it covers wood, nails, drywall and light metal in one case without leaving you short on a blade mid-teardown. If you only need one specialist, the Milwaukee The Ax is the strongest choice for nail-embedded wood, and the Diablo Steel Demon covers the thick metal that a bi-metal blade cannot touch.
Budget the consumables, not the sticker. Our bathroom gut and deck section together consumed several blades across the sets, so buy a multi-pack and a carbide blade in the same order. Whichever blade you land on, check the fit, break it in on clean material first, and swap it early rather than pushing it to failure.
