Christopher R. ★★★★★ Oct 20, 2026

The closed coat on this disc really grabs and holds onto the metal shavings, keeping the work area much cleaner than other discs I've tried. It feels like a heavy-duty cloth backing that just doesn't tear apart under pressure.

I’ve been using this 20-inch disc with my rotary sander for heavy metalwork, and the heavy X-weight cloth backing really holds up without tearing. It cuts through rust and scale faster than the cheap discs I tried before.

The closed coat on this 20-inch disc really grips the metal without loading up, and the heavy X-weight cloth backing holds up to aggressive use. I’ve been using it on a large sander for hours, and it’s still cutting cleanly.
