Mirka 5-in. P150 PSA Sanding Disc Roll for Sanding Applications (23-314-150)

The Mirka 23-314-150 5 Inch PSA Linkroll Sanding Disc P150 is a 5 inch adhesive-backed sanding disc for surface preparation and finish sanding. This is a sanding disc designed for general sanding, smoothing, and prep work with compatible sanders and PSA backup pads. Model Number: 23-314-150.

What matters here is the combination of a common 5 inch disc size and a 150 grit abrasive. That puts this disc in a useful middle range for smoothing surfaces after heavier sanding and before finer finishing steps. If you are cleaning up wood, prepping painted surfaces, or refining a workpiece before the next coat or pass, P150 is a practical grit to keep on hand.

This Mirka abrasive is built in a PSA format, which means pressure sensitive adhesive backing. For the user, that means direct attachment to a compatible PSA sanding pad instead of a hook and loop setup. If your sander or backup pad is set up for PSA discs, this style gives you a clean, secure hold and a straightforward disc change process.

The product listing identifies this as an ORO PSA Linkroll disc, which places it in Mirka's abrasive lineup for finish and prep work. Mirka has a strong reputation with pros who care about consistent scratch patterns and dependable abrasive performance, especially in body shop, woodworking, and refinishing environments where surface quality matters as much as speed.

Pack size also matters when you are stocking consumables. Source data lists a box quantity of 10, so this is aimed less at the one-off user and more at the shop, contractor, or serious DIYer who wants the right grit ready to go without buying a full large case. That makes it a sensible pickup for routine sanding tasks where 150 grit gets used often.

If you already run a 5 inch PSA sander setup, the Mirka 23-314-150 5 Inch PSA Linkroll Sanding Disc P150 makes sense for woodworking, paint prep, refinishing, and general finish sanding. It is a good fit for users who know the backing style they need and want a recognized abrasive brand in a grit that sees a lot of real-world use.
