The Mirka 24-35M-120 Iridium 3 x 5 Grip 54H 120 sandpaper sheet is a sanding abrasive sheet built for surface preparation and finish sanding. This is a sandpaper sheet designed for sanding wood, filler, coatings, and similar shop or jobsite surfaces with a compatible 3 x 5 grip-style sander. Model Number: 24-35M-120.

What matters here is the combination of size, grit, and hole pattern. The 3 x 5 inch format is a standard size for many detail and finish sanders, while the 120-grit rating gives you a useful middle step for smoothing material after rougher prep or before moving to a finer grit. If you are trying to keep a sanding sequence efficient, this is the kind of grit that earns its keep.

The 54-hole layout is there for dust extraction on sanders that use this pattern. In real use, better dust flow means less buildup on the abrasive face and a cleaner work surface, especially during repeated sanding passes. That matters whether you are cleaning up filler, flattening primer, or refining a wood surface before the next step.

Mirka labels this sheet as Iridium with a grip backing. The grip format is meant for quick attachment and removal on compatible sanding pads, which helps when you are changing sheets often through a sanding progression. For pros and serious DIY users, that kind of simple time savings adds up fast over a full project.

This pack includes 50 sheets, so it makes sense for users who go through abrasives regularly instead of buying one-off replacements. It is a practical fit for body shop work, finish carpentry prep, woodworking, paint prep, and general refinishing where a 3 x 5 grip sheet and 54-hole pattern match the tool in hand.

If your sander is set up for 3 x 5 grip sheets with a 54-hole dust pattern, the Mirka 24-35M-120 Iridium 3 x 5 Grip 54H 120 sandpaper sheet is a straightforward choice. It is for buyers who care less about flashy claims and more about getting the right sheet size, the right grit, and enough quantity to keep working.
