DLC – mill Radius

Dry milling of Aluminum

  • DLC(Diamond Like Carbon) is an amorphous material with high hardness and low friction rate, and has similar character of Diamond.
  • Application for milling in Aluminum Ultra high speed cutting in DRY.

Excellent chip evacuation

  • Trouble free milling by unique flute geometry Stable & extra long tool life is realized b DL film & its unique flute.

High Accuracy on Corner Radius

  • The accuracy on Corner Radius is excellent .
