The Mirka 24-6MH-1000 IRIDIUM 6in Grip 121H 1000 sanding disc is a premium 6-inch hook and loop sanding disc sold in a 50-pack. This is a sanding disc designed for fine surface sanding and finish work. Model Number: 24-6MH-1000. If you need a disc that cuts clean, resists loading, and leaves a refined surface, this is the kind of abrasive that earns its keep.

Mirka positions the Iridium line as a universal paper abrasive, and the material stack explains why. It uses a mix of ceramic and aluminum oxide grains on a flexible paper backing, which gives you a good balance of cutting speed and finish quality. In real use, that matters because a disc that cuts quickly but still leaves a controlled scratch pattern saves time on every sanding step.

The 1000 grit is geared toward fine sanding, surface prep, and finish refinement rather than aggressive stock removal. That makes this disc a better fit when you're working through higher grit stages and trying to improve the final surface instead of just knocking material down fast. For painters, finish carpenters, refinishers, and anyone doing detail sanding, grit choice is everything, and 1000 grit tells you this disc is meant for the cleaner end of the process.

The 121-hole pattern is one of the more important details here. Good dust extraction keeps the abrasive face cleaner, helps reduce clogging, and supports a more even cut across the whole disc. That usually means better consistency from disc to disc and less wasted time dealing with pilling or premature wear.

Mirka also calls out a precision coating and a backing designed for flexibility. That is useful when you're sanding surfaces that are not perfectly flat or when you want the disc to stay in contact without feeling overly stiff. A flexible paper disc can help you maintain better control, especially during finer sanding stages where surface quality matters more than brute force.

This Mirka sanding disc makes the most sense for users who already run 6-inch random orbit sanders with hook and loop pads and want a premium abrasive for finish-focused work. If your goal is speed, cleaner sanding, and a long-lasting disc in a fine grit, the Mirka 24-6MH-1000 IRIDIUM 6in Grip 121H 1000 sanding disc is a smart buy.
