Enjoy a 50 to 60 percent improvement in tear strength thanks to the flexible fiber-reinforced, latex-saturated backing of this ProSand A975 medium grit paper H&L vacuum disc. The P-graded, seeded-gel ceramic alumina abrasive provides a fast cut rate and long life, and the water-based stearate coating and vacuum hold maximum dust extraction while minimizing loading. This disc is a superb choice for finishing and sanding with your random orbital sander and right angle grinder, and the hook and loop back makes mounting and changing easy.
