Quickly attach the A275OP fine grit paper H&L disc to a random orbital sander or a right angle grinder by means of the convenient hook and loop back. The P-graded, heat-treated aluminum oxide abrasive provides fast cuts and reliable results, while the fiber-reinforced B-weight latex-saturated backing delivers 50 to 60 percent greater tear resistance without sacrificing flexibility. The water-based, non-pigmented stearate No-Fil coating ensures there's no color transfer to your workpiece, and the open coat design helps resist loading. This disc is an ideal tool for fine grit dry sanding, micro-finishing and finishing jobs on woods, aluminum, fiberglass and composites.
