Mirka Bulldog Gold 5-in. 220 Grit PSA Sanding Discs, No-Hole 100-Pack (23-332-220)

Mirka 23-332-220 5" Bulldog Gold (No-Hole) 220 Grit PSA Sanding Discs is a 5-inch pressure sensitive adhesive sanding disc pack made for finishing and stock removal. This is a sanding disc designed for surface preparation and finish sanding on a compatible 5-inch PSA sander pad. Model Number: 23-332-220. If you need a disc that cuts cleanly, stays consistent, and comes in box quantity that makes sense for regular shop use, this one is built for that job.

The 220 grit rating puts this Mirka sanding disc in the fine-sanding range, where surface quality starts to matter just as much as material removal. That makes it a solid choice for smoothing filler, refining primer, prepping painted surfaces, and cleaning up wood before the next finishing step. Mirka describes Bulldog Gold as suitable for finishing and heavy stock removal, which tells you the abrasive is meant to stay productive instead of glazing over right away.

The abrasive material here is aluminum oxide, which is a proven choice for everyday sanding work because it balances cut speed, durability, and value. On the job, that means the disc keeps working across a range of materials without getting dull too quickly. For shops and contractors who burn through abrasives every week, that kind of consistency matters more than flashy claims.

Mirka also uses high-strength resin bonding for stronger grain support. In plain terms, that helps the abrasive grains stay anchored to the backing under pressure, which supports a longer service life and a more predictable scratch pattern. The semi-open coat design adds another practical benefit: it helps produce a more even finish while reducing the tendency to load up as quickly as a tighter coat can.

A special stearate coating is included to improve resistance to clogging and loading. That matters when you are sanding materials that can gum up a disc and kill performance early. Better resistance to loading means the disc stays cutting longer, leaves a more uniform finish, and wastes fewer pieces during repetitive sanding work.

The no-hole format is important. These are not vacuum-hole discs, so they are intended for use with a matching no-hole or solid-face 5-inch PSA backup pad. If your setup is built around PSA discs and you want full-face contact, this style gives you a secure stick-on attachment and a simple disc change process. The 100-count box also makes sense for body shops, cabinet shops, painters, and serious DIY users who want to keep the same abrasive on hand instead of buying small mixed packs.

Who should buy these? Anyone doing regular finish sanding with a 5-inch PSA setup and who wants dependable Mirka abrasive performance. They make the most sense for woodworking, autobody prep, paint and primer sanding, and general surface prep where a fine, consistent scratch pattern is the goal.

Mirka 23-332-220 5" Bulldog Gold (No-Hole) 220 Grit PSA Sanding Discs keep finish work moving

This is the kind of sanding disc you buy when you care about a clean finish, steady cut, and not wasting half the box on loaded-up paper.

• Who it's for: Woodworkers, painters, body shop techs, and serious DIY users running a 5-inch PSA sanding setup.
• Why it stands out: Aluminum oxide abrasive, resin-bonded grain support, stearate coating, and a semi-open coat all work together to keep the cut consistent and resist clogging.
• Worth knowing: These are PSA no-hole discs, so make sure your sander pad matches that format. If you need hook and loop or dust-extraction holes, this is not the right disc.

• What type of sander pad does this use? It is made for a 5-inch pressure sensitive adhesive pad, not a hook and loop pad.
• Does this disc have dust extraction holes? No. This is a no-hole sanding disc.
• What abrasive material is used? These discs use aluminum oxide abrasive.
• Is 220 grit meant for finish work? Yes. The 220 grit rating is in the fine range and is commonly used for finish sanding and surface refinement.
