The Mirka Bulldog Gold PSA Disc 5 in P280 is a coated abrasive sanding disc made for fine surface sanding and finish prep. This is a sanding disc designed for surface preparation and fine finishing work. Model number 23-332-280. If you need a 5 inch PSA disc that sticks down fast, sands cleanly, and comes in shop-friendly bulk quantity, this one is built for exactly that job.

The big story here is the combination of a P280 grit and aluminum oxide abrasive. That puts this disc in the finer range where you're cleaning up a surface rather than doing heavy stock removal. For wood, coatings, filler, and general finishing steps, that matters because the abrasive pattern needs to be controlled and consistent, not overly aggressive.

Mirka uses a paper backing on this disc along with a pressure sensitive adhesive backing. In real use, PSA discs are about speed and simplicity. Peel, stick, sand, and swap when needed. If your setup is built around PSA-backed abrasives, this style keeps downtime low and avoids the extra step of hook and loop alignment.

This Mirka Bulldog Gold PSA Disc 5 in P280 is a no-hole disc, so it is intended for sanding setups that do not require a vacuum hole pattern through the abrasive. That is an important detail before you buy. If your pad depends on a dust-extraction hole layout, you will want to match that up correctly. If you run a solid-face PSA pad, this no-hole design is the right format.

The 5 inch diameter is one of the most common disc sizes in sanding, which makes this a practical choice for shops and finish work where that size is already standard. It also comes in a 100-pack, so it makes sense for repeat work where you want the same grit and cut quality available without reordering every few jobs.

The Bulldog Gold-23 series is aimed at users who want a dependable paper-backed abrasive from a brand that knows finishing. This is not a specialty shape or oddball format. It is a straightforward Mirka abrasive disc for users who know exactly what they need: 5 inch size, PSA attachment, P280 grit, and no-hole construction.

Who should buy it? Anyone already running a 5 inch PSA sanding system and needing a finer grit disc for surface prep, cleanup, or finish-stage sanding. It is a smart fit for body shops, paint prep work, woodworking, cabinet work, and general shop sanding where consistent grit and bulk quantity matter more than flashy features.
