The Mirka 23-314-500 5 in. P500 PSA Disc Roll is a pressure sensitive adhesive sanding disc roll made for fine surface preparation and finish sanding. This is a sanding abrasive disc designed for smoothing surfaces before finishing, coating, or the next sanding step. Model Number: 23-314-500. If you need a consistent 5 inch PSA disc in a fine grit and want quantity on hand instead of grabbing discs one at a time, this pack is set up for that kind of work.

The core of this product is straightforward and useful: a 5 inch disc size, P500 abrasive grit, aluminum oxide grain, and PSA backing. In real use, that means a disc that is aimed at lighter material removal and cleaner refinement rather than aggressive stock removal. The pressure sensitive adhesive backing gives the disc a firm mount on the correct PSA sanding pad, which matters when you want solid contact and predictable sanding across the full face of the disc.

Mirka uses a paper backing on this coated abrasive disc, which helps keep the disc flexible enough for general sanding tasks while still being practical for shop use. The no-hole design is the right fit when your setup does not require dust-extraction holes in the disc pattern. That makes this Mirka disc roll a simple choice for users who want to avoid mismatch issues with hole patterns and just need a full-face PSA sanding disc for the right application.

This pack includes 100 discs, so it makes sense for users who go through abrasives regularly and do not want to stop mid-job to reorder. It is a good fit for painters, finish sanders, refinish work, and general surface prep where a P500 sanding disc is the right step in the process. If your work calls for a fine, consistent abrasive from a known brand and you are set up for 5 inch PSA discs, this one is an easy, practical buy.
