Polycrystalline Diamond

SUMIDIA Series

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, copper, magnesium and zinc alloys.
