Tackle any sanding project with the SKIL 20-Piece Mixed Triangle Sanding Paper Kit. Aluminum oxide grain creates a consistent scratch pattern and helps create a finer finish when used on wood, metal, drywall, fiberglass, or painted surfaces. Hook and loop backing makes changing discs quick and easy, and the hole patten matches the sander pad on SKIL detail sanders for maximum dust extraction. The kit includes various grit for sanding needs from coarse to extra-fine.
