PCD (Polycrystalline Diamond)
SUMIDIA
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.
SUMIDIA's superior wear resistance achieves longer tool life, high speed, high efficiency
and high precision in non-metal cutting and non-ferrous metal applications including
aluminium, copper, magnesium and zinc alloys.
Characteristics DA1000
The DA1000 utilises Sumitomo Electric Hardmetal's proprietary sintering technology to achieve a high-density sintered material
made of ultra-fine diamond particles that has superior wear and fracture resistance and longer tool life.
