Leo ★★★★★

The J-weight backing really lets these belts flex into tight contours without creasing, which saved me time on a curved railing project. They cut through stainless steel smoothly without loading up.

Lucy ★★★★★

Grabbed these for a mixed metal-and-wood shop project, and the J-weight backing really holds up on my orbital sander without tearing or folding over. The aluminum oxide cuts fast and keeps an edge longer than the cheap belts I’ve burned through before.

Steven ★★★★★

I was pleasantly surprised by how flexible the J-weight cloth backing is on these belts — it curves around my sander's platen without any stiff spots. Cuts through metal evenly and the grit holds up through heavy use without loading up.
