Mirka Iridium 6-in. 120 Grit Hook and Loop Sanding Disc, 121H Pack of 50 (24-6MH-120)

The Mirka 24-6MH-120 Iridium 6 Inch Grip 121H 120 sanding disc is a hook and loop sanding disc pack built for general sanding and surface preparation. This is a sanding disc designed for stock removal, surface leveling, and finish prep on compatible 6 inch grip sanders and backing pads. Model Number: 24-6MH-120.

What matters here is the balance of size, grit, and hole pattern. The 6 inch disc size is a standard choice for a lot of shop and jobsite sanding work because it gives you enough coverage to move efficiently across panels and larger surfaces without getting awkward in the hand. The 120 grit rating makes this a practical working grit for smoothing filler, knocking down primer or sealer edges, refining previous sanding scratches, and getting surfaces ready for the next finishing step.

The 121-hole layout is there for a reason. More dust extraction points across the face of the disc help pull sanding dust away from the work area instead of letting it pack into the abrasive. That usually means more consistent cutting and less loading, especially when you’re sanding materials that tend to clog paper quickly. If dust control matters in your workflow, this pattern is one of the main reasons to choose this disc style.

The grip attachment format keeps disc changes simple. On a compatible hook and loop pad, you can pull off a worn disc and get back to work fast without messing with adhesive backing. That is a real time-saver if you’re stepping through multiple grits or burning through discs during prep work.

This pack quantity also makes sense for people who sand regularly instead of occasionally. With 50 discs in the box, it is a better fit for body shops, woodworkers, finish prep crews, and serious DIY users who do not want to run short in the middle of a project. It is also a cleaner way to stock one commonly used grit for repeat work.

If you need a Mirka abrasive for day-to-day sanding work, this one is aimed at users who want a standard 6 inch hook and loop sanding disc with a 120 grit cut and a dust-focused 121-hole pattern. It is a solid choice for anyone doing routine surface prep where fast disc changes, broad dust extraction, and dependable mid-grit performance matter more than gimmicks.
