Short answer: the WORKPRO 150-piece 5 inch 8-hole pack is the best sanding disc for random orbital sanders for most people, because it covers ten grits from 60 to 600 in one box, uses aluminum oxide grain, and fits the 8-hole pattern common on 5 inch pads. If your sander is 6 inch, the POWERTEC 6-hole discs are the one to buy. Everything else in this roundup is a deliberate upgrade in grain, backing or dust extraction.
The disc is the only part of a random orbital sander you replace on every project, and it is where most frustration actually lives. A hole pattern that does not line up kills dust extraction and leaves swirls, a dull grain stops cutting and starts burnishing, and a loaded disc gouges soft pine in seconds. So I picked these twelve by the four things that decide whether a disc works: abrasive grain, backing type, hole pattern and attachment system.
I compared twelve packs across grain type, backing, hole pattern and grit spread, and read the customer feedback on each one to separate consistent patterns from one-off complaints. Manufacturer performance numbers are quoted as claims, not as our own measurements, because I could not verify them independently. If you are still choosing the machine itself, our guide to the best orbital sanders for fine woodworking is worth a look first, since pad diameter and hole pattern follow the sander you already own.

1. WORKPRO 150 Piece 5 Inch 8-Hole Discs – Best Overall Assortment
WORKPRO 150 Pack 5 Inch Sanding Discs Sandpaper, 8-Hole Hook and Loop
Aluminum oxide grain
10 grits from 60 to 600
8-hole pattern
Napped hook and loop
Pros
- Ten grit grades cover stripping through finish sanding
- 8-hole pattern keeps dust extraction working
- Fits 5 inch pads from major brands
- Large 150 piece count reduces repurchasing
Cons
- Occasional reports of backing scuff on the pad
- Less long-lived than 3M abrasives on very hard jobs
WORKPRO is the best sanding disc for random orbital sanders because it removes the most common friction point: grit. Ten grades from 60 to 600 sit in one box, so a full sequence from flattening a rough panel to knocking down a coat of finish does not mean five separate orders.
The grain is aluminum oxide with an anti-clog treatment, which is the sensible default mineral for wood, and the napped hook and loop backing is the kind that peels off cleanly instead of shredding when you change grit. Buyers describe the attachment as close to name-brand discs, and the 8-hole pattern lines up with the standard 5 inch random orbital pad.
Where it earns its place in my shop is coverage rather than peak performance. It is not the disc I reach for when stripping heavy paint, because a ceramic or zirconia grain holds an edge longer, but for deck boards, doors, stair treads and general furniture work it does everything asked of it. Owners also point out it handles metal, glass, plastic and leather as well as wood.
One small complaint repeats in the reviews: a few buyers report a fine fabric or paper scuff left behind on the pad after a disc delaminates. Rare, but worth knowing, and a worn pad makes it more likely. The other recurring note is that these do not last as long as 3M abrasives on very hard jobs, which is the honest cost of buying a large assortment.
What this pack is genuinely good at
Finishing passes, not heavy removal. Once you are past 120 grit, disc life matters far less than consistency, and a big mixed pack keeps the grits you need in the same box. It is also the safest recommendation for someone who has never counted the holes on their own pad, since 8 holes is the most common 5 inch layout.
When to buy something else instead
If you are stripping multilayer paint, spending hours on a single coarse grit, or finishing an oil-based polyurethane, the aluminum oxide grain here will load faster than a ceramic or silicon carbide alternative. If your pad hooks are worn, discs of any brand will start to lift, so spend the time on the pad instead.
2. S SATC 72 Piece Assortment – Best Budget Starter Pack
S SATC 72 PCS 5 Inch 8 Hole Hook and Loop Adhesive Sanding Discs Sandpaper for Random Orbital Sander 40 60 80 120 180 240 320 Grits
Aluminum oxide grain
Seven grits from 40 to 320
Open-coat with stearate
Hook and loop
Pros
- Seven grits cover most prep to medium finishing
- Open coat resists clogging and pilling
- Hook and loop holds firmly in use
- Handles paint
- rust and stairs
Cons
- Adhesion suffers on a worn pad
- Grits can run slightly aggressive
- Some discs wear out fast on fine woodwork
S SATC is the pack to buy if you want a usable assortment without committing to a large box. Seventy-two discs spread across seven grits, from 40 through 320, cover the bulk of prep, flattening and finish work on a home project.
The technical detail that matters here is the open-coat structure with a stearate coating. Open coat means the grains sit further apart on the backing, so debris has somewhere to go instead of loading the surface, which is why reviewers report good results stripping paint and rust as well as sanding stairs and furniture.
Fit is the other strength. The hook and loop backing is described as gripping firmly without delaminating, and buyers confirm it fits the common 5 inch random orbital models. The 5 inch 8-hole format again covers the majority of pads in circulation.
The drawbacks show up in the fine end of the range. Several buyers say the grit cuts a little more aggressively than an equivalent branded grit, and a minority report short disc life on delicate woodwork. The most common complaint of all is that the hook will not hold if your pad’s hooks are already flattened.
What this pack is genuinely good at
Prep work and paint removal, where volume matters more than finish quality. Because the coating is anti-clog, it behaves well on a surface that will generate a lot of debris, and the assortment means you are not reordering mid-project.
When to buy something else instead
It is the wrong choice for a final pass under a varnish or a glue-up, where a coarser or less consistent scratch pattern shows. It is also a poor test of whether a brand is good, because adhesion problems usually point at the pad rather than the disc.
3. Aiyard 80 Grit 100 Pack – Top Rated for Aggressive 80 Grit Work
Aiyard 5-Inch 8-Hole Hook and Loop Sanding Discs 80-Grit, 100-Pack
Fused alumina grain
100 discs at 80 grit
Pre-punched 8 holes
Velcro attachment
Pros
- Fused alumina cuts aggressively and holds its edge
- 8 holes align with standard 5 inch pads
- Stays attached and swaps quickly
- Buyers compare it favorably to store discs
Cons
- Backing can degrade in long sessions
- Shorter life than premium abrasives
Aiyard sits at the top of the rating range here at 4.7 across more than 6800 reviews, and the reason is consistency rather than a single spectacular feature. One hundred discs of 80 grit, every one from the same production run, means the third disc cuts like the first.
The grain is fused alumina, which is a step up in hardness from ordinary aluminum oxide and explains the reports of aggressive cutting that outlasts store-brand discs. The improved binder is what keeps the disc from snapping in two when you catch an edge, and the pre-punched 8 holes take the guesswork out of pad alignment.
It works far beyond wood. Buyers use it on aluminum alloy, fiberglass, rubber, stone, painted surfaces and non-ferrous metals, which makes it a reasonable second use for anyone doing auto or fabrication work. Owners also describe clean, even removal with no disc shedding.
The honest limitation is the backing. A small share of reviews, mostly from outside the US, report the hook and loop degrading during very long sessions, and a few note shorter life than premium abrasives at the same workload. If you are running a disc past the point of dulling, that is where it will show.
What this pack is genuinely good at
Dialing in a coarse grit. Because it is a single grit, you can buy it on purpose once you know 80 is your working step, and a hundred discs will cover repeated passes on rough stock, planed lumber or a scuffed table. The high rating reflects very few complaints beyond long-session backing wear.
When to buy something else instead
A single-grit pack means completing a sanding sequence requires more orders, so it is a poor first purchase for a beginner. It is also not the disc for a final finish pass, and it is the wrong size for a 6 inch pad.
4. POWERTEC 120 Grit 25 Pack – Best Value Single Grit for Finishing
POWERTEC 25PK, 120 Grits, Sanding Discs 5 Inch – Hook and Loop, 5 Inch 8 Hole Aluminum Oxide Sandpaper Discs, Woodworking Sanding Pads for Random Orbital, Palm, Air, DA & Pneumatic Sander (45012)
Resin bonded aluminum oxide
120 grit, 25 discs
8-hole pattern
Open coated grain
Pros
- Resin bonding gives heat resistance on long passes
- Open coat limits buildup and clogging
- Broad sander compatibility
- Backing resists disconnection
Cons
- Only 25 discs per pack
- Single grit means buying each step separately
POWERTEC 120 grit is a small, unglamorous pack that does exactly one thing well. Twenty-five discs of medium-grit aluminum oxide, resin bonded, with an 8-hole pre-punched pattern for a 5 inch pad.
Resin bonding is the detail worth knowing. It is what lets an abrasive tolerate the heat a random orbital sander generates at speed, and it is the reason reviewers report consistent cutting across wood, painted surfaces and metal rather than a disc that glazes after a few minutes.
Compatibility is unusually broad for this category. The same 5 inch 8-hole disc is listed for random orbital, circular, rotary, palm, power, air and DA pneumatic sanders, which means one pack can cover a small sander and a larger one in the same shop.
The two complaints are both about the pack size rather than the discs. Twenty-five is a small count for a machine that eats them quickly, and because it is single grit, finishing a full sequence means ordering again. Plan for that up front and this becomes a reliable filler pack rather than a complete answer.
What this pack is genuinely good at
120 grit, specifically. That is the workhorse step between flattening and finish sanding, and owners report clean results at that grit with dust extraction holding up as long as a vacuum is connected. It suits anyone who already knows their sequence and just needs a dependable medium grit.
When to buy something else instead
Skip it as a first purchase, because a single grit box forces multiple orders to complete a project, which is the complaint forum users raise most often about buying discs online. It is also not the tool for stripping or for a very fine final pass.
5. POTUINOM 165 Piece Mixed Grit Set – Best for High Volume Prep
POTUINOM 165 PCS 5 Inch Sanding Discs Random Orbital Sander Sandpaper
Hard aluminum oxide grain
Nine grits plus extra 40
8-hole pattern
Hook and loop backing
Pros
- Largest disc count among the packs here
- Nine grits cover a full sequence
- Pre-punched holes aid dust extraction
- Anti-clogging grain resists loading
Cons
- Less disc life than premium brands
- Discs wear out faster than name-brand equivalents
POTUINOM solves a different problem: running out. One hundred and sixty-five discs across nine grits, with the counts weighted toward the coarse end where disc life is shortest, means a full refinishing job from one purchase.
The abrasive is a hard, high-quality aluminum oxide that resists clogging and cuts quickly, which is the practical difference between a disc that works on soft pine and one that glazes within minutes. The hook and loop backing is the kind that holds through long sessions, and it is what reviewers credit for secure adhesion.
Fit is the other draw. Owners report that the pre-punched 8 holes line up correctly with standard 5 inch random orbital sanders, so the disc sits flat on the pad and the extraction ports stay open. With that much supply on hand, you can move through a full sequence without stopping to reorder.
What you trade away is disc life. Reviews repeatedly describe these as comparable to home improvement store discs rather than to premium abrasives, and note that individual discs wear out faster. For a one-off job that trade makes sense, and for someone who is done after the project it is a good one.
What this pack is genuinely good at
Volume. If you are stripping a staircase, refinishing a dining table, or working through a stack of donated cabinets, the sheer count means you will not stop mid-project to reorder. The extra 40 grit discs matter here, because coarse grit is where discs disappear fastest.
When to buy something else instead
It is the wrong buy for a person who wants a disc to last through several projects, because the per-project cost works out higher once the shorter life is counted. It is also not what you want for a very fine final pass, since nothing in the range goes past 600.
6. 3M Xtract Cubitron II Net Disc 710W – Premium Ceramic Pick for Dust Control
3M Xtract Cubitron II Net Disc, 710W, Multi-Grade, 5 in x NH, Die 500X
Ceramic precision-shaped grain
Net mesh with no hole alignment
12 piece multi-grade pack
Hook and loop
Pros
- Net structure removes the need to align holes
- Precision-shaped grain fractures into fresh edges
- One pack covers 80+ through 320+
- Can be rinsed and reused when loaded
Cons
- Marked for industrial and occupational use only
- Higher cost per disc for occasional work
- Only 12 discs in the pack
The 3M Xtract net disc is the most interesting mechanism in this roundup, because it has no holes at all. The abrasive is carried on an open net, so there is no hole pattern to line up, and the dust never has anywhere to sit between the disc and the surface.
The grain is precision-shaped ceramic. Those shaped grains fracture as they wear, exposing fresh cutting edges instead of rounding off, which is the reason buyers report discs that keep cutting long after an ordinary aluminum oxide disc has glazed, and a glass-like result at 320 grit. Twelve discs cover 80+ through 320+, two of each, which is enough to run a whole mid-stage sequence.
Three manufacturer claims belong here, attributed rather than asserted. 3M states that the net material extracts up to 99 percent of the dust produced, and that the precision-shaped grain fractures as it wears to expose fresh cutting edges. The dust behaviour matches what owners report; the figures themselves are 3M’s, not ours.
Buyers also note the practical benefit of reusability. A loaded disc can be rinsed and used again, which matters on oiled or waxed surfaces where loading is guaranteed rather than possible. The complaints are consistent too: the pack is small at twelve discs, and the per-disc figure makes it hard to justify for occasional hobby work.
What this disc is genuinely good at
Long sessions with a vacuum attached, and finishing stages where the surface shows every scratch. Because the grain keeps regenerating its edges, several owners describe switching to these as their default disc after trying them, particularly for metal fabrication, primer and gelcoat sanding, and composite work.
When to buy something else instead
Skip it if you sand a few hours a month. There is also a practical reason to read the listing before you commit, since this pack is labelled for occupational rather than consumer use. For a hard corner or an edge, a film-backed disc will outlast it.
7. YNZDRWA 70 Piece 9 Grit Set – Best for Very Fine Finishing Stages
YNZDRWA 70 PCS 5 Inch 8-Hole Sanding Discs, 9 Mixed Grits
Aluminum oxide grain
Nine grits from 40 to 800
Anti-static abrasive
8-hole pattern
Pros
- Only pack here reaching 800 grit
- Accurate grit ratings against spec
- Good adhesion for a value pack
- Upgraded hook and loop changes discs quickly
Cons
- Dulls faster on rough surfaces
- Around 70 percent of the life of higher quality discs
- Better for light prep than heavy removal
YNZDRWA is the only coarse-to-fine value pack that reaches 800 grit, and that single fact puts it in a category of its own. If your project ends at a very fine pass, this is the one that can finish the sequence without a second order.
Otherwise it is a conventional, well-made aluminum oxide assortment: nine grits from 40 to 800, an 8-hole pattern and an anti-static abrasive that reviewers say stays sharp. Grit ratings are reported as accurate to the spec, which matters more than it sounds when you are trying to hit a consistent surface.
Adhesion is better than several competing value packs in the reviews, with owners noting it holds where other brands repeatedly come loose.
The limitation is explicit in the feedback. These dull faster on rough surfaces, and reviewers put the life at roughly 70 percent of higher-quality discs. That is a fair trade for prep and light work, and a poor one if you are removing a lot of material quickly.
What this pack is genuinely good at
Furniture refinishing and touch-up work where the last passes matter. It covers the range from 40 up to 800, so it can take a piece from stock removal through to a finish-ready surface, which is why reviewers place it as a mid-range option for woodworkers and restorers.
When to buy something else instead
Do not buy it to power through rough lumber. At heavy removal the disc dulls quickly, and you will spend more of the pack than the task requires. If your only goal is the 600 grit step, the larger WORKPRO or POTUINOM packs get you there with more discs.
8. POWERTEC 80 Grit 6 Inch Discs – Best for 6 Inch Random Orbital Sanders
POWERTEC 80 Grit, 25 PK, 6 Inch Sanding Discs – Hook and Loop, 6-Hole Aluminum Oxide Orbital Sander Pads, Woodworking & Paint Round Sandpaper for Random Orbital, Air, Pneumatic & DA Sanders (45208)
Aluminum oxide grain
6 inch, 6-hole format
25 discs at 80 grit
Cloth backing
Pros
- Covers 6 inch random orbital
- air
- pneumatic and DA pads
- 80 grit suits rough stock removal
- Hook and loop stays connected in use
- The only 6 inch disc listed here
Cons
- Lowest average rating here at 4.4
- Single grit pack
- Only 25 discs
Most disc roundups ignore 6 inch pads entirely, so this pack is worth its place. If your random orbital sander takes a 6 inch disc with six holes, this is the option here that will physically fit it.
The format is 6 inch, 6-hole, 80 grit, with a cloth backing carrying a hook and loop attachment. That backing choice is the useful detail: it holds through repeated changes and does not tear the way a paper-backed disc can when you peel it off.
The discs are listed for random orbital, air, pneumatic and DA sanders with 6 inch pads, and owners report effective rough sanding and paint removal with reliable attachment. Because the six-hole pattern keeps extraction moving on a pad that cannot take 8-hole discs, it fills a compatibility gap most listings ignore.
Its 4.4 average is the lowest in this group, and the one-star share reflects durability complaints rather than fit or cut quality. It is also a single-grit pack of 25, so you will be buying again for each step of a sequence.
What this pack is genuinely good at
Rough work on a 6 inch machine. The 80 grit is the right choice for flattening old material, knocking down heavy texture and stripping paint, and it is the only disc in this roundup that will physically fit a 6 inch pad.
When to buy something else instead
Do not buy it for a 5 inch sander, and do not expect a 6 inch disc to fit a 5 inch pad. It is also the wrong choice if you want to complete a project in one order, since the pack is single grit and small.
9. NOOKEYA 52 Pack Mixed Grit – Best for Sorted Grits on the Go
52 Pack 5 Inch 8-Hole Hook and Loop Sanding Discs Sandpaper Red Round 60 80 120 220 320 Mixed Grits Sandpaper for Random Orbital Sander
Aluminum oxide grain
52 discs across five grits
Grit printed on disc backs
8-hole pattern
Pros
- Grit number printed on every disc
- Five grit assortment at a low per-disc figure
- Anti-static grain stays sharp
- Velcro attachment prevents coming loose
Cons
- Range stops at 320
- so nothing for very fine finishing
- Moderate disc life against premium brands
NOOKEYA solves a small problem that annoys people constantly: telling your discs apart. The grit number is printed on the back of every disc, so you can pick a grit in seconds instead of squinting at an edge in a dusty shop.
The pack holds 52 discs across five grits: 11 each of 60 and 80, then 10 each of 120, 220 and 320. That distribution is weighted toward the working end of a sequence, which is where most time is spent on a typical project.
Underneath the labelling, it is a straightforward anti-static aluminum oxide disc with a pre-punched 8-hole pattern and velcro attachment. Reviews are largely positive on adhesion and on dust extraction, with owners citing the universal 5 inch fit as a reason it works across their machines. The limit is the top of the range, since nothing goes past 320 and reviewers describe the disc life as moderate next to premium brands.
What this pack is genuinely good at
Grading, shaping and prep, and any job where you are switching grit often. The printed labels also make it the easiest pack to audit, which matters when you are working through a sequence and want to know what you have left.
When to buy something else instead
It will not take you to a finished surface on its own, so anyone doing a final pass under finish needs a 400 to 600 grit disc from another pack. The moderate life also makes it a poor choice for long sessions of heavy removal.
10. S&F STEAD & FAST 60 Piece Wet Dry Set – Best for Wet Sanding and Polishing
S&F STEAD & FAST 5 inch Wet Dry Sanding Discs Hook & Loop 60 pcs
Silicon carbide grain
400 to 2000 grit
Waterproof backing paper
Wet or dry use
Pros
- Only wet and dry silicon carbide option here
- Smooth satin finish with little swirl
- Waterproof backing holds for wet sanding
- Tear resistant construction
Cons
- Fine grits only
- so no coarse work
- Low grits tear on sharp edges
This is the pack to reach for when you are sanding a finish rather than a surface. Silicon carbide, sixty discs from 400 to 2000 grit, on a tear-resistant waterproof backing paper that allows wet or dry use.
Silicon carbide is the right mineral for this stage. It produces a finer scratch pattern than aluminum oxide at the same grit number, which is exactly what you want under an oil-based polyurethane or on a gelcoat, and owners report a smooth satin result with very little buffing afterwards.
The wet capability is the real specialty. Reviewers sand aluminum wheels and car body panels under water with these, and the waterproof backing is what holds up when a dry paper disc would dissolve. They also clean up well with a microfiber cloth after dry sanding, and the hook attachment stays secure through long jobs.
Two limits are clear. There is no coarse grit here at all, so this cannot strip or flatten anything, and the listing itself advises against using the lowest grits on rough or sharp edges because they tear early.
What this pack is genuinely good at
Wet sanding metal, and any final pass on a cured finish. The 1000 to 2000 grits take a surface from matte to smooth without the swirl pattern that coarser aluminum oxide leaves.
When to buy something else instead
It will not touch raw wood, stripped paint or anything needing material removed, so it complements a coarser pack rather than replacing one. It is also the wrong grit range for a 6 inch pad user looking for heavy work.
11. Serious Grit 5 Inch 8-Hole 50 Pack – Best for Corners and Reuse
Serious Grit – 5-Inch 8-Hole Sanding Discs – P80-220 Assortment – 50 Pack
Polyester film construction
50 discs, P80 to P220
60 percent nylon hook and loop
Zinc stearate anti-clog coating
Pros
- Film backing resists tearing at corners and edges
- Discs can be cleaned and reused many times
- Anti-clog coating keeps the full face working
- Nylon hook and loop is denser than paper backing
Cons
- Premium cost per disc against value packs
- Coarse grits lose effectiveness faster
- Only 50 discs in the pack
Serious Grit is built around one material decision: polyester film instead of paper. Film does not crease or tear when you fold the disc to sand into a corner, and that single property is why owners of this pack keep coming back to it for furniture work.
The backing is 60 percent nylon hook and loop, which is a denser loop than the paper-backed packs in this roundup. That density is what allows the same disc to be taken off, cleaned and refitted several times instead of being discarded after one session.
A heat-treated zinc stearate coating handles the loading problem, shedding dust before it builds into a glaze, and that matters most when a vacuum is connected and the dust actually has somewhere to go. Reviewers describe a flatter, more consistent finish than paper, mesh or net discs produce, with fewer visible swirl marks.
Fit covers the standard 5 inch 8-hole pattern used by most major sander brands. The compromise is per-disc cost, and the observation that the coarser end of the range loses effectiveness faster than the finer grits.
What this pack is genuinely good at
Detailed work where a torn disc ruins a panel: edges, profiles, mouldings and cabinets. It is also the choice when you want to clean and reuse a disc rather than discard it, which is why it turns up in so many finish-sanding kits.
When to buy something else instead
The math does not work if you sand constantly and do not mind replacing discs, since the per-disc figure is the highest here. It is also not the cheapest way to cover a whole house of shelves, where volume matters more than reusability.
12. Mirka Abranet 5 Inch Mesh Discs – Best for Putty, Paint and Mesh Fans
Mirka Abranet 5 Inch Assortment Mesh Sanding Discs, Hook and Loop, 35 Pack
Aluminum oxide mesh grain
Seven grits from 80 to 600
35 disc assortment
Hook and loop
Pros
- Open mesh resists clogging on long sessions
- Consistent smooth results across materials
- Works in a machine or by hand
- Seven grits in one assortment
Cons
- Smallest assortment at 35 discs
- Premium price per disc
- Lowest review count at 212
Mirka Abranet is the other mesh option here, and the one most often recommended for putty, filler and paint work. Thirty-five discs, five each of 80 through 600 grit, with an open mesh structure that lets dust pass through the disc rather than settle on it.
Because the mesh is open across the whole face, there is no hole pattern to align, which removes the most common compatibility mistake. The practical result is a disc that resists clogging and holds its cutting performance on a long session, particularly on putty and soft paint where a paper disc would glaze within minutes.
The 4.7 rating reflects consistent finish quality across a wide material range, including wood, putty, paint, plastic and metal. The discs work in a random orbital sander or by hand, which is useful for the corners a machine cannot reach.
The trade-offs are assortment size and price. Thirty-five discs covers a mid-range sequence but is a thin margin of supply, the per-disc figure is the highest of the mesh options here, and at 212 reviews this is the thinnest evidence base in the set, so treat the consistency reports as encouraging rather than proven.
What this pack is genuinely good at
Putty, filler and painted surfaces, where loading is the main enemy. The mesh keeps cutting even as debris builds, and the seven-grit spread means a full mid-range sequence for fine finishing or a cabinet project without ordering by grit.
When to buy something else instead
It is hard to justify for occasional work, and the small pack means more frequent repurchasing than any other option here. For a corner-heavy job you will reuse, the film construction of a polyester disc is the more durable choice.
How to Choose Sanding Discs for a Random Orbital Sander
What are the holes for on an orbital sander?
The holes align with the dust extraction ports on the sander pad. Air and sawdust are pulled through them into a vacuum or bag, so debris does not sit between the disc and the wood. A mismatch between the disc holes and the pad ports is the main cause of fast clogging and those swirling scratches that no amount of careful sanding explains.
Can I use 8-hole discs on a 5-hole sander?
Yes, and this is the single most useful compatibility fact for most buyers. A 5 inch pad with 8 holes accepts an 8-hole disc, and a 5 hole pad accepts 8-hole discs in the many listings that carry both patterns, because the extra holes simply sit over solid pad. A 6 hole disc only fits a pad designed for 6 holes, and a 6 inch disc will not fit a 5 inch pad at all. Count the holes on your pad, measure the diameter, and check whether the pad holes are equally spaced or clustered in the centre before you order.
Which is better, hook and loop or PSA?
Hook and loop is better for almost every modern random orbital sander, because discs swap in seconds and can be stored and reused. PSA, which stands for pressure-sensitive adhesive, gives a firmer and flatter bond that cuts faster on flat stock, but a PSA disc cannot be removed or reused without ruining it, so it suits older pads and disc sanders rather than a random orbital you intend to keep.
What PSA means on a sanding disc label is simply that the abrasive is glued to the backing with a pressure-sensitive adhesive layer instead of a loop fabric. Forum users overwhelmingly prefer the hook and loop system, and the reason is the same one that decides it in practice: grit changes take seconds and your pad stays usable.
Aluminum oxide, ceramic or zirconia: which grain should you buy?
Aluminum oxide is the affordable default and handles wood, paint and metal adequately. Ceramic grain costs more per disc but stays sharp longer and resists loading, which pays off on paint, primer and metal. Zirconia sits in between, cutting hard and lasting well on dense hardwood. The honest rule is that grain choice only matters once you start loading discs rather than wearing them out, so start with aluminum oxide and upgrade if your discs glaze before they dull.
What grit sandpaper should I use for my orbital sander?
Start at 60 or 80 grit to flatten, move through 120 to 150 for shaping and refining, then 180 to 220 to prepare for finish. Two warnings from experienced users: do not jump to 1000 grit early, because a random orbital sander makes deep scratches very efficiently, and on soft woods like pine do not begin with the coarsest grit available or the grain will tear out. Stop at 180 to 220 before a stain or oil, since going finer can reduce how much the finish absorbs.
How do I make sanding discs last longer?
Connect the vacuum, and let the weight of the sander do the work. Pressing down is the most common mistake, because pressure generates heat, heat loads the abrasive, and a loaded disc then gouges the soft wood underneath it. Clean the disc with a crepe block as you go, quarter-turning it each time so the wear spreads across the face, and keep the pad’s hooks clear of dust. If discs start lifting or flying off, replace the backing pad rather than blaming the brand, since worn hooks ruin even good discs. And if you are working on old paint in a house built before 1978, test for lead before you sand anything.
Frequently Asked Questions
What grit sandpaper should I use for my orbital sander?
Start at 60 or 80 grit for flattening, move through 120 to 150 for shaping, and finish at 180 to 220 before stain or finish. Avoid jumping straight to very fine grits, because a random orbital sander makes deep scratches quickly.
How to sand with a random orbital sander?
Let the sander’s own weight do the work rather than pressing down, keep the vacuum connected so dust is extracted, and change grit in even steps. Rotate the disc a quarter turn whenever you clean it so wear spreads across the face.
Which is better, hook and loop or PSA?
Hook and loop is better for almost all modern random orbital sanders because discs swap in seconds and can be reused. PSA gives a firmer, flatter bond that cuts faster on flat stock, but discs cannot be removed and reused without being ruined.
What are the holes for on an orbital sander?
The holes line up with the dust extraction ports on the sander pad, pulling air and sawdust into a vacuum or bag so debris does not sit between the disc and the wood. A mismatch between the disc hole pattern and the pad ports causes fast clogging and swirling scratches.
What does PSA mean on sanding discs?
PSA stands for pressure-sensitive adhesive. It means the abrasive is bonded to the backing with a glue layer rather than a loop fabric, so the disc attaches firmly but cannot be removed and reused without tearing.
The Verdict
For most 5 inch random orbital sanders, the WORKPRO 150-piece 8-hole pack is the best sanding disc for the money you spend, because one box covers a full sequence and the 8-hole pattern fits the majority of pads. Buy the Aiyard 80 grit pack when you know which grit you want and want a consistent cut, and go with the 3M Xtract net disc when dust control and disc longevity justify a higher figure and a lot of hours at the machine. Six inch owners should take the POWERTEC 6-hole discs, and anyone finishing a cured finish or wet sanding metal needs the silicon carbide set. Whatever you choose, count your pad holes before you order, and let the sander’s weight do the work.
