The Mirka 23-608-800 23 Series Grip-On Sanding Disc is a 3 inch hook and loop sanding disc made for fine finish sanding and surface prep. This is a hook and loop sanding disc designed for fine finish sanding. Model Number: 23-608-800. With P800 grit aluminum oxide abrasive and a 3 inch diameter, it is a good fit for users who need controlled, light sanding rather than aggressive material removal.

What matters here is the balance between finish quality and disc life. The P800 grit is firmly in the fine-sanding range, so this disc is better suited to refining a surface, blending scratches from earlier sanding steps, and getting workpieces ready for the next stage. If you are working through a grit sequence, this is the kind of disc you reach for near the finish line, not at the rough shaping stage.

Mirka lists this disc with aluminum oxide grain and a semi-open coat. In practical terms, that means it is built to keep cutting while helping reduce clogging and pill forming. That is important in high-speed sanding, where loaded abrasive can leave a poor finish and waste discs. The Gold series is known for being a dependable general-purpose abrasive when you need a clean finish and predictable performance.

The grip backing makes setup straightforward on a matching 3 inch hook and loop backing pad. That is a real time-saver if you change discs often, especially during finish work where moving from one grit to the next is part of getting the result right. This version is a no-hole disc, so it is the right pick when your setup does not require vacuum hole alignment or when you are running on a solid 3 inch backing pad.

Backing construction also matters on a small finishing disc, and this one is listed with C-weight paper backing. That gives it enough body for controlled sanding while still staying flexible enough for detail work and contour-friendly applications that call for a lighter touch. On a 3 inch disc, that makes it useful for smaller surface areas where larger discs feel clumsy or overly aggressive.

This Mirka abrasive is a strong choice for finish-oriented users who already know the value of stepping through grits properly. It makes sense for auto body prep, woodworking finish sanding, composite work, and general shop use where surface quality matters. If you need a 3 inch grip disc for fine sanding on a hook and loop sander, the Mirka 23-608-800 23 Series Grip-On Sanding Disc gives you a proven abrasive material, a finish-focused grit, and a 50-piece pack that keeps you stocked for repeat work.
