Dry drilling 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 drilling & milling in Aluminum Ultra high speed cutting in DRY !
Excellent chip evacuation
Trouble free drilling by unique flute geometry Stable & extra long tool life is realized by DLC film & its unique flute.
