أقراص PSA صلبة من Norton SG/H920 سيراميك أمريكية (لفة) حبيبات 120F

I've been through about 30 discs so far with my random orbital sander, and the ceramic grain really cuts through old varnish without loading up like the cheaper aluminum oxide ones. The PSA backing stays put even on a warm backing pad, which was a nice surprise for a roll of 100.

I needed a reliable disc for metal prep and these Norton ceramic ones hold up through heavy use. The 120 grit cuts cleanly without loading up, and having them on a 100-count roll makes restocking easy.

The 120F grit on these PSA discs cuts fast without loading up, even on maple and oak that had a bit of old finish left. The ceramic blend holds its edge noticeably longer than the aluminum oxide I was using before, and the roll dispenses cleanly without tearing the backing.
