DME Company Abrasive Stone

FOR GENERAL AND SPECIAL PURPOSE STONING, FINISHING AND POLISHING OF MOLDS AND DIES GENERAL PURPOSE STONES These silicon carbide, vitrified bond stones are available in two types: TYPE A: For use on steel prior to heat treating or for steel hardness lower than 40 HRC. TYPE B: For steel hardness higher than 40 HRC. Ideal for restoring finish after heat treating. SPECIAL PURPOSE STONES Available in three types: TYPE E (EDM STONES): Aluminum oxide crystals in a medium hard vitrified bond, with a special resin treatment to improve cutting action on hard surface crusts, such as those produced by EDM. TYPE M (MEDIUM OIL FILLED): Aluminum oxide crystals in a hard vitrified bond, with a special oil fill which eliminates the soaking often recommended for abrasive stones. The oil fill provides additional lubrication to prevent loading and assure optimum stock removal. Ideal for heat treated tool steels. TYPE F (D-M-E FLEX): Aluminum oxide crystals in a hard resin bond provide some flexibility to reduce breakage. Ideal for polishing deep ribs and fine details.
