SUMIDIA Series Polycrystalline Diamond Grades Excellent wear resistance with longer tool life in high-speed, high-efficiency and high-precision cutting of non-ferrous metals and non-metals. SUMIDIA is a polycrystalline diamond material made from sintered diamond powder that was A first created using our proprietary technology in 1978. SUMIDIA's superior wear resistance achieves longer tool life in high speed, high efficiency and high precision non-metal cutting and non-ferrous metal applications including aluminum, Grades copper, magnesium and zinc alloys.
