Best Sanding Discs for Random Orbital Sanders

Updated on September 18, 2026

For most people, the best sanding discs for a random orbital sander are Mirka Gold Multifit discs: they cut fast, last well and fit any 5″ dust-extraction pad, whatever its hole pattern. If dust is your main problem, Mirka Abranet mesh discs pull dust through their whole surface and barely clog. For the longest life per disc, 3M’s Xtract net discs are the premium pick.

Discs are the part of sanding you keep buying, and cheap ones cost more than they save: they clog, shed grit, fly off the pad and leave stray scratches. Below are five discs for 5″ random orbital sanders, from a budget variety pack to reusable and premium options, a comparison table, and a guide to hole patterns, grits and disc types.

Best Sanding Discs Compared

Sanding Disc Reviews

1. Mirka Gold Multifit 5″ Hook-and-Loop Discs

Best Sanding Discs Overall

Mirka Gold is the long-running general-purpose line from Mirka, the Finnish abrasives maker, and the Multifit version solves the most common disc problem: hole patterns. Mirka makes its universal pattern to fit any 5″ dust-extraction pad, so it works on a 5-hole pad, an 8-hole pad or a multi-hole one without thinking about alignment.

The abrasive is aluminum oxide on a paper backing, with what Mirka calls high-strength resin bonding to hold the grain in place. Mirka rates it for both finishing and heavy stock removal. It is sold one grit per box of 50, which is how you should buy discs anyway: you go through 80 and 120 far faster than 220.

• ✅ Universal hole pattern for any 5″ dust-extraction pad
• ✅ For stock removal and finishing
• ✅ Boxes of 50 per grit
• ❌ One grit per box: you need several boxes for a full sequence

Best For: Anyone who sands regularly and wants one disc that fits every sander in the shop.

2. Mirka Abranet 5″ Mesh Disc Assortment

Best for Dust Extraction

Abranet is a mesh, not a sheet with holes. With a vacuum attached, dust is pulled through the entire disc, not just through 5 or 8 holes, so very little stays between the abrasive and the wood. That matters for two reasons: the disc clogs much less, and the surface stays clean enough to see what you are doing.

This pack has 35 discs across seven grits, 80, 120, 180, 240, 320, 400 and 600, so it covers everything from leveling to sanding between coats of finish. Mesh fits any 5″ hook-and-loop pad regardless of hole pattern. Mirka lists it for wood, putty, paint, plastic and metal.

Shop Now at Amazon

• ✅ Dust pulled through the whole disc
• ✅ Resists clogging on finishes and paint
• ✅ Seven grits in one box, 80 to 600
• ❌ Works best with a vacuum; without one, much of the advantage is lost

Best For: Sanders connected to a shop vac or extractor, and anyone sanding finishes, filler or paint.

3. 3M Xtract Net Disc 710W

Longest-Lasting Premium Disc

3M’s net disc uses its Precision-Shaped Grain, triangular ceramic particles that keep fracturing into sharp edges instead of rounding over. 3M claims twice the life and cut-rate of leading competitor net discs and says the net backing extracts up to 99% of the dust. Those are the maker’s numbers, not ours, but the principle is sound: a grain that stays sharp needs less pressure, and less pressure means fewer swirl marks.

3M lists woodworking first among its recommended uses, with grades from 80+ to 320+ and a maximum speed of 12,000 RPM, which suits standard random orbital sanders. It is sold one grade per box of 50.

Shop Now at Amazon

• ✅ Sharp ceramic grain, cuts with light pressure
• ✅ Net backing for dust extraction, any hole pattern
• ✅ Grades 80+ to 320+
• ❌ Highest cost per disc here; overkill for occasional DIY

Best For: Hardwoods, big projects and anyone who counts cost per tabletop, not per box.

4. Diablo SandNet Reusable Discs with Connection Pad

Best Reusable Discs

Diablo’s SandNet discs use a net design that resists clogging, and when they do load up you can rinse them and use them again. The kit includes a connection pad that goes on your sander’s pad first; the net discs then attach to it. Diablo says the system fits both 5- and 8-hole orbital sanders, and the ceramic-blend abrasive is rated for wood, metal and plastics.

Ten discs in assorted grits is a small pack, but the point of SandNet is that each disc lasts much longer than a paper one, so you change discs less often.

Shop Now at Amazon

• ✅ Washable and reusable
• ✅ Fits 5- and 8-hole sanders with the included pad
• ✅ Net design against clogging
• ❌ The connection pad adds a layer between sander and disc

Best For: DIYers who hate changing discs and want less waste.

5. Dura-Gold 5″ 8-Hole Variety Pack

Best Budget Variety Pack

Fifty 8-hole discs, 10 each of 60, 80, 120, 220 and 320 grit, in one box at the lowest cost per disc here. Dura-Gold describes the abrasive as aluminum oxide fused with zirconia alumina, which it says resists clogging and loading. It is a sensible first box: you learn which grits you actually use, then buy those in bulk.

Check your pad first: this is an 8-hole pattern, the standard on DEWALT, Makita, Ryobi and many others. On a 5-hole pad some holes won’t line up, and dust collection suffers.

Shop Now at Amazon

• ✅ Five grits, 60 to 320, in one box
• ✅ Lowest cost per disc
• ❌ 8-hole only
• ❌ Won’t last as long as the Mirka or 3M discs

Best For: New random orbital owners and occasional DIY projects.

How I Chose These Discs

I looked for discs from abrasive makers that finishing shops actually buy (Mirka, 3M, Diablo) plus one budget pack, all currently sold on Amazon in the US. For each one I used the maker’s own specifications: abrasive type, backing, hole pattern and grits. I left out discs whose listings say they are for industrial use only, and generic packs that don’t name their abrasive. When a performance figure appears, it is the maker’s claim and is attributed to them.

How to Choose Sanding Discs for a Random Orbital Sander

Size: 5″ or 6″

Match the disc to the pad. Most home random orbital sanders are 5″, which is why every pick here is 5″. If you have a 6″ sander, most of these lines are also made in 6″. My random orbital sander reviews explain the difference between the two sizes.

Hole Patterns: 5-Hole, 8-Hole, Multi-Hole and Mesh

The holes are how the sander pulls dust out from under the disc. If they don’t line up with the pad, the dust stays under the disc, clogs it and scratches the wood.

• 8-hole: the most common on 5″ sanders from DEWALT, Makita, Ryobi and others.
• 5-hole: found on some older 5″ sanders. Count the holes on your pad before you buy.
• Multi-hole: dozens of small holes that line up with any pattern, like Mirka Multifit.
• Mesh and net: no holes at all; dust passes through the whole disc. Fits any pad.

If you own more than one sander, or aren’t sure which pattern you have, multi-hole or mesh discs remove the guesswork.

Paper, Film, Mesh or Net

Paper discs are the standard and the cheapest per disc. Film backings are thinner and more consistent and are common for fine finishing. Mesh and net discs cost more but clog much less and extract dust best, especially on paint, finish and filler.

Abrasive Mineral

Aluminum oxide is the all-round standard for wood. Ceramic and precision-shaped ceramic grains cut faster and last longer, and are worth it for heavy use and hardwoods. Zirconia blends sit in between.

Hook-and-Loop vs PSA

Almost every current random orbital sander uses hook-and-loop discs, which you can peel off and reuse at a different grit. PSA (sticky-back) discs are for older pads without hooks and can’t be removed without ruining them. Buy hook-and-loop unless your sander’s pad is smooth.

What Grit Sandpaper for a Random Orbital Sander?

For bare wood, a typical sequence is 80, 120, 150 or 180, finishing at 220 before a clear coat. Use 60 or 80 for stripping old finish, and 320 to 400, at low speed, between coats. My sandpaper grit chart covers every job.

Make Your Discs Last Longer

• Connect a vacuum. Dust trapped under the disc is the main cause of clogging. See the best shop vacs for dust collection.
• Don’t press. Pressure heats the disc and loads it with dust. Let the sander’s weight do the work, as I explain in how to use an orbital sander.
• Clean clogged discs with an abrasive cleaning stick while the sander runs.
• Protect the pad. When the hooks wear, discs fly off. A thin pad saver or interface pad protects the hooks and is cheaper than a new backing pad.
• Change discs on time. A dull disc polishes instead of cutting. Swap it the moment it stops working.
