Quickly attach the H&L A275OP Fine-Grit Paper Disc to a random orbital sander or right-angle grinder with the convenient hook-and-loop backing. The P-grade, heat-treated aluminum oxide abrasive ensures fast cuts and reliable results, while the B-weight fiber-saturated latex backing provides 50-60% greater tear strength without sacrifice flexibility. The water-based, non-pigmented stearate No-Fil coating ensures there is no color transfer to your part, and the open coating design helps withstand loads. This disc is an ideal tool for fine-grit dry sanding, micro-finishing and finishing work on wood, aluminum, fiberglass and composites.
