Ella O. ★★★★★

Used a 20 micron disc to finish a knife handle and the scratch pattern came out beautifully uniform. The PSA backing held tight even when switching between a rigid pad and a soft interface.

Ryan ★★★★★

Cutting through some tough dried epoxy today and these 20-micron discs left a smooth, consistent finish without clogging up. The black silicon carbide really bites into the material without loading the disc.

Lily F. ★★★★★

I picked up a pack of these 20 micron discs for some fine finishing work, and the silicon carbide cuts cleanly without loading up like other discs I’ve used. They stick firmly to the pad right out of the box.
