Alexander ★★★★★

The X-weight backing really holds up when I'm hogging off hard maple, no stretching or burning like the thinner belts I've used. Ran one belt through a full tabletop glue-up and it still had plenty of grit left.

Lily D. ★★★★★

I run these on my 4x36 belt sander and after a full afternoon of shaping oak they still had plenty of grit left. The cloth backing flexes around the curves without cracking, which my old paper belts never managed.

Hazel ★★★★★

I've been running these belts on my 6x48 sander and the aluminum oxide grit still cuts clean after a few hours of oak, no glazing yet. The cloth backing doesn't stretch or fray at the splice either, which was my main gripe with the last ones I bought.
