Create an impressive finish when you attach the durite A475 fine grit paper PSA disc to your random orbital sander or right angle grinder. With its P-graded silicon carbide abrasive, the disc easily cuts through the toughest of materials and veneers and its flexible fiber-reinforced B-weight latex paper backing keeps it flexible and resistant to tears. Minimize loading and color transfer to your work surface thanks to the disc's water based stearate and non-pigmented No-Fil® coating. The durable, long-lasting disc is the ideal choice for hard-to-sand metals, fiberglass and composites, as well as hard and soft woods.
