Key Features
Overview
The Mirka 24-5MH-500 Iridium 5 Inch Grip 89-Hole Sanding Disc 500 Grit is a fine-grit hook and loop sanding disc sold in a 50-pack for finish sanding and surface refinement. This is a sanding disc designed for light material removal, final prep, and smoothing work before the next finishing step. Model Number: 24-5MH-500.
What matters here is the combination of a common 5 inch disc size, a fine 500 grit abrasive, and Mirka’s grip-style hook and loop attachment. That setup makes these discs quick to swap out during sanding sessions, which is a real advantage when you are working through grit changes and do not want to waste time fighting worn discs off the pad.
The 89-hole pattern is the other important detail. On a compatible sander and backing pad, that hole layout supports dust extraction across a large part of the disc face. Cleaner extraction helps keep the abrasive cutting more consistently and reduces the chance of sanding debris getting trapped between the disc and the work surface.
Because this is a 500 grit disc, it is best suited to refining rather than aggressive stock removal. It makes more sense for finish prep, between-coat sanding, and dialing in the last stages of surface quality than for stripping rough material. If your goal is a cleaner final surface, this grit is where the product earns its keep.
The Mirka Iridium sanding disc format is a good fit for users who already run 5 inch hook and loop random orbital sanding setups and want a disc that is easy to change and packed in job-ready quantity. A 50-pack gives you enough discs for production work, cabinet and trim prep, refinishing tasks, or shop use where you go through fine grits regularly.
If you are a woodworker, finisher, body shop user, painter, or serious DIYer working toward a smoother surface, this Mirka sanding abrasive is aimed at you. The key is making sure your sander or backing pad accepts 5 inch grip discs and that the 89-hole pattern matches your dust-extraction setup closely enough to get the benefit.
Clean Finish Prep Without the Fuss
This disc is built for the stage where surface quality matters more than fast removal. The fine grit and multi-hole layout make it a strong choice for users trying to keep the work clean and consistent as they move toward final finish work.

Pro Tip
When you are using a fine 500 grit disc, a clean pad matters more than people think. If the backing pad is loaded up or the holes are not lined up well, you can lose dust extraction and end up rubbing debris back into the surface instead of refining it.
