The Mirka 24-342-080 Iridium 6 Inch PSA sanding disc is a 6 inch pressure sensitive adhesive abrasive disc sold in a 100-pack for surface preparation and sanding work. This is a sanding disc designed for stock removal, shaping, and prep sanding on a compatible 6 inch PSA backing pad. Model Number: 24-342-080.

What matters here is the format. A 6 inch disc gives you good coverage on larger surfaces, while the 80 grit rating puts this disc in the part of the sanding process where speed and cut matter more than final finish. If you are knocking down filler, leveling rough surfaces, or getting a workpiece ready for the next grit, this is the kind of abrasive you reach for first.

Mirka's Iridium line is aimed at users who go through abrasives regularly and need consistent performance from disc to disc. On the job or in the shop, that means less messing around with random cut quality and more predictable sanding from the first disc in the box to the last one.

The PSA attachment style is the other big point. If your setup uses pressure sensitive adhesive discs, this format gives you a direct stick-on mounting method for a secure hold during sanding. That matters when you want a clean, flat interface between the abrasive and the pad, especially on broad surfaces where uneven contact shows up fast.

This Mirka sanding abrasive makes the most sense for body shops, woodworkers, finish prep crews, and general shop users who already run 6 inch PSA sanders or backing pads. It is also a solid fit for serious DIY users doing filler work, paint prep, or aggressive sanding steps before moving into finer grits.

If you need a Mirka abrasive that covers a lot of surface area, uses a PSA mounting style, and comes in a shop-friendly quantity, the Mirka 24-342-080 Iridium 6 Inch PSA sanding disc is a straightforward buy. It is not a finish-sanding disc. It is the disc for the earlier part of the process where you need the abrasive to get to work.

A smart bulk buy for rough sanding stages

The Mirka 24-342-080 Iridium 6 Inch PSA sanding disc is the kind of shop consumable that makes sense when you need a steady supply of real working grit, not a couple discs hanging on a peg.
