Julian J. ★★★★★

Finally got these for my random orbital sander and the 3/4 arbor fits perfectly. These black silicon carbide discs cut well and leave a smooth finish on hardwood.

Jacob S. ★★★★★

Black silicon carbide cuts through the hardened steel I sharpen noticeably faster than the aluminum oxide discs I used before. The plain back sits flat without any wobble on the arbor, which makes a difference when I’m doing fine finishing passes. Grit selection was accurate, too—the finer discs lea

Penelope ★★★★★

The 3/4" arbor fits my bench grinder perfectly, and the plain back design means they don't slip or wobble mid-sanding. I grabbed a few different grits and the silicon carbide cuts through metal fast without loading up, even on the finer finishes.
