Joseph ★★★★★

Loading these belts onto my pneumatic sander was straightforward, and the aluminum oxide grit cut through several pieces of oak without any noticeable dulling. I've been really impressed with how evenly they wear down compared to other general-purpose belts I've tried.

Amelia F. ★★★★★

Needed a replacement pack for my old worn-out belts and these fit my pneumatic sander perfectly right out of the box. The aluminum oxide grit cuts through primer and light rust without clogging up too fast.

Grace Z. ★★★★★

These belts chew through body filler and paint on my air file sander without loading up, even on tight curves. The closed coat aluminum oxide holds its bite far longer than the cheap rolls I've tried, so a 10-pack stretches a good while.
