With a flexible fiber-reinforced, latex-saturated backing, the ProSand A975 medium grit paper H&L vacuum disc provides a 50 to 60 percent boost in tear strength. The P-graded seeded-gel ceramic alumina abrasive delivers quick cuts and longevity. Its water-based stearate coating maximizes dust extraction while reducing loading, making it ideal for finishing and sanding with random orbital sanders and right angle grinders.
