Diablo SandNet discs in 5 and 6 in. The abrasive sits on an open mesh instead of paper, so dust pulls through the whole face rather than only at the holes — there is no hole pattern to line up, and the disc loads far more slowly on paint, filler and joint compound. Aluminum oxide versions run 120 through 400 grit for finishing, ceramic blend 80 and 100 for stock removal. Sold in 10 and 50 packs and in mixed-grit assortments.
