Our Super Red Stearate line is our premium grade DA sanding discs. These red p-graded discs are heat treated and have a premium aluminum oxide grain that creates a very fast cutting action. The stearate coating on the open coat grain minimizes loading and reduces heat buildup, providing cool cutting. The resin on the resin bond further extends the disc life and enables the paper to be folded without cracking. The integrated film layer in the bonded paper backing provides durability and water resistance, so these discs can be used wet.
