Type C Discs are fiber-backed grinding discs that are fully resin bonded. They are coated with a tough, durable aluminum oxide abrasive and feature closed coat construction. These grit discs measure 7 inches by .875 inches. Bulk Abrasive Discs are available in diameters ranging from inches up to 1 inches. There is a wide range of abrasives and grades to choose from including Fre-Cut which resists loading and filling, Resinite bonded discs for heat resistance and Tri-M-ite with silicon carbide and Three-M-ite with aluminum oxide for sharp, clean cutting. Tough paper backings on discs also range from a versatile production weight to very strong D and E weights.
