Grade Polycrystalline Diamond Excellent wear resistance, longer tool life and high-speed, high-efficiency, high-precision cutting of non-ferrous metals and non-metals. SUMIDIA is a polycrystalline diamond material made from sintered diamond powder that was first created using our proprietary technology in 1978. Insert Grades SUMIDIA’s superior wear resistance achieves longer tool life in high speed, high-efficiency and high-precision machining of non-metal and non-ferrous metal applications including aluminum, copper, magnesium and zinc alloys. A SUMIDIA Binderless uses nano-polycrystalline diamond for the cutting edge, demonstrating excellent wear resistance and fracture resistance. In particular, it achieves extended tool life and machining accuracy superior to Carbide Coated conventional polycrystalline diamond when machining hard brittle materials such as cemented carbide.
