Monocrystal Diamond Cutting Tool New D

New D



  1. ・Less variation in tool life and cutting ability and 1.5 to 2 times longer tool life than conventional tools.
  2. ・Less fusion of chips to make this tool suitable for dry/semi-dry machining (MQL machining).
  3. ・Sharp cutting to enable burr-free machining.



・Automotive parts (piston, aluminum wheel, commutator)
・Electronic equipment parts (plastic lens, resin parts)
・HDD parts, aluminum die cast alloy, other non-ferrous metals
