Enjoy the combination of flexibility and increased tear strength of the fiber-reinforced C-weight latex-saturated backing on this A290 coarse grit paper PSA vacuum disc. This disc is a good choice for blending, coarse grit dry stripping, stock removal and sanding composites, aluminum, hard and soft woods and fiberglass. It also features a pressure sensitive adhesive that allows easy disc changes on fast-paced tasks. The disc's P-graded aluminum oxide provides a consistent finish and fast cut rate and its water-based stearate coating, open coat and vacuum holes maximize dust collection while minimizing loading.
