The Mirka 23-352-320 Gold 8 in PSA Sanding Disc P320, Pack 50 is a fine-grit sanding abrasive for finish prep and surface refinement. This is a sanding disc designed for fine finishing and between-coat sanding on flat surfaces. Model Number: 23-352-320. If you need a consistent 320-grit cut in an 8 inch pressure sensitive adhesive format, this is the kind of shop consumable that keeps finishing work moving without a lot of fuss.

What matters here is the combination of size, grit, and attachment style. The 8 inch diameter gives you good surface coverage, which helps on larger workpieces where a smaller disc would mean more passes. The P320 grit is on the finer side, so it is better suited to smoothing, blending, and prep work than heavy stock removal. That makes it a practical choice when the goal is surface quality, not aggressive material removal.

The PSA backing is the other big point. Pressure sensitive adhesive discs are meant for a secure, direct attachment to a compatible sanding pad. That setup can be a good fit when you want a firm hold and a clean working face without the bulk of another attachment system. For users who already run PSA-backed abrasives, this Mirka disc keeps the process straightforward: peel, stick, sand, replace.

Mirka Gold abrasives are widely known in finishing and sanding work for being a dependable everyday abrasive line. In practical terms, that means this disc is aimed at users who care about predictable surface prep and want a familiar grit step they can keep stocked in quantity. A 50-pack is not just a packaging detail. It matters if you burn through discs regularly in a cabinet shop, body shop, finishing area, or on steady remodeling work.

This Mirka sanding disc is best for users who already know they need an 8 inch PSA disc and specifically want a fine P320 finish step. It makes sense for woodworking, paint prep, refinishing, and general surface finishing where consistency matters more than raw aggression. If your work is final sanding, light defect cleanup, or prep before the next coating stage, this grit and format are right in the zone.
