أقراص كربيد السيليكون سوداء مقاس 2.5" بفتحة PSA

I've been using these discs for sanding down old paint on a metal cabinet, and the silicon carbide grit cuts through it without clogging up like my old aluminum oxide ones did. The adhesive backing is strong enough that I can swap discs quickly on my sander without them peeling off mid-job.

I was skeptical about the adhesive backing, but these discs stick firmly and don't lift at the edges, even on vertical surfaces. The silicon carbide grit cuts through old paint quickly without clogging.

Finally found some discs that don't peel off mid-job—the adhesive is aggressive enough to stay put on my sander. They're cutting through old paint and rust evenly without loading up too quickly.
