These discs have multiple layers of brick-shaped abrasive arranged in a pattern to create highly consistent finishes. The layers contain up to four times as much abrasive material as other sanding discs, so they last longer. Wide gaps between the abrasive layers prevent dust and debris from building up on the abrasive surface. Made from the most common abrasive material, aluminum oxide, these discs are hard enough to sand steel and wood. They cost less than zirconia alumina discs but wear down faster. Quickly attach, remove, and reuse discs with a compatible sanding tool or backup pad (sold separately).
