Enjoy a fast cut rate and a consistent finish with the premium, P-graded, heat-treated aluminum oxide abrasive of this A275OP coarse grit paper H&L disc. The water-based stearate No-Fil coating resists loading and avoids transferring color to your work, and the fiber-reinforced, B-weight latex-saturated backing improves tear strength by 50 to 60% while remaining flexible during blending, stripping and sanding.
