4 1/2" × 7/8" قرص رفرف نوع 27 (مسطح) - سيراميك مستورد ماكرو ديسك

Used the 60 grit on some welds and it flattened them fast without gouging the metal. The ceramic material held up noticeably better than the aluminum oxide discs I'd been buying.

Bought the 36 grit in the single-pack and it ate through welded seams way faster than the cheap discs I've been using. The flat Type 27 profile kept the contact area steady on flat stock, and the ceramic grain didn't glaze over after a few passes.

Picked up the 80 grit version to strip some old paint off a metal shelf and it chewed through it way faster than the standard discs I was using. The ceramic material really does seem to last longer without wearing down unevenly. Already ordered another pack to keep on hand.
