Customer Reviews (4.6 / 5 · 5 reviews)

Alexander ★★★★★

These belts cut through steel surprisingly fast and stay sharp way longer than regular sanding belts. The pyramid structure really does keep exposing fresh grit, so I'm not swapping them out every few pieces.

Sebastian ★★★★★

Bought this for some shop sanding and it’s noticeably smoother than the regular belts I was using. The pyramid structure really does seem to keep cutting longer without loading up.

Isabella G. ★★★★★

Used one of these on a knife that was getting dull, and the pyramid grit kept cutting evenly across the whole belt without loading up. It’s been through a few projects now and still feels fresh.
