2" x 42" 3M 977F 雷加利特陶瓷砂帶

The 40Y grit cuts through hardened steel much faster than the aluminum oxide belts I was using before. I ordered a pack of ten and the first one has held up through several dozen knife blades already.

I've been using this ceramic belt for knife sharpening, and the 40Y grit gives a surprisingly smooth finish without loading up. A single belt has lasted through several projects already.

The 40Y grit on these belts chews through metal fast without loading up, which is exactly what I needed for some heavy sanding on a knife bevel. They're 2x42, so they fit my bench sander perfectly, and the ceramic grain holds its edge way longer than the aluminum oxide ones I used before.
