The Mirka 24-3MH-180 Iridium 3 in Grip 20H 180 Grit Sanding Disc is a 3 inch hook and loop sanding disc sold in a 50-pack for surface preparation and finish sanding. This is a sanding disc designed for sanding and surface refinement on a compatible backing pad. Model Number: 24-3MH-180. If you use small-format random orbit or detail sanding setups and want fast disc changes with a known abrasive line from Mirka, this is the kind of consumable that keeps the work moving.

The key spec here is the 180 grit rating. In real use, that makes this disc a solid choice when you are stepping down from rougher scratch removal and moving toward a smoother, more controlled surface. It is fine enough for refinement work, but still practical for everyday prep where you want visible progress without jumping straight to very fine finishing grits.

Mirka pairs that grit with a ceramic and aluminum oxide abrasive blend. That matters because abrasive mix has a direct effect on how the disc cuts and how long it keeps cutting. A ceramic blend typically helps maintain a sharper bite under use, while aluminum oxide is a proven all-around abrasive for common sanding jobs. Put simply, this combination is aimed at giving you a disc that does not feel spent too early.

The 3 inch diameter makes this a compact sanding abrasive for smaller pads, tighter areas, spot repair work, and jobs where a full-size 5 inch or 6 inch disc would be more tool than you need. That smaller format can be the right call when you want better control around contours, edges, or localized work zones. It is also a practical size when you are trying to keep sanding targeted instead of touching more surface than necessary.

The Grip format means hook and loop attachment, so disc changes are straightforward. That is a small detail until you are on your tenth or twentieth disc in a day. Quick attachment helps reduce downtime, and it also makes it easier to move through grit sequences cleanly instead of stretching a worn disc longer than you should.

This Mirka disc is identified as a 20H version, which is the designated hole pattern in the product naming. For buyers who are matching abrasives to an existing pad setup, that is an important fit detail. Always match the disc pattern and size to your sander or backing pad so you get proper support and the dust extraction performance your setup is built for.

Who should buy it? Anyone already running Mirka-style sanding abrasives in a 3 inch hook and loop format and needing a medium-fine disc for prep and finishing steps. It makes the most sense for users who go through discs regularly and want a 50-pack on hand rather than buying in small quantities. If your work depends on consistent sanding results and fast changeovers, this is the practical kind of abrasive that earns its keep.
