Grades SUMIDIA Series Polycrystalline Diamond 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 first created using our proprietary technology in 1978. SUMIDIA's superior wear resistance achieves longer tool life in high speed, high efficiency A Grades and high precision non-metal cutting and non-ferrous metal applications including aluminum, copper, magnesium and zinc alloys.
