Products Features

1. Special designed drill tip: Special designed drill tip will increase the Centering Ability and Chip breaker ability. Thus,the processing efficiency will be increased.
2. Much sharper cutting edge: The much sharper cutting edge can decrease the cutting resistance and and torque. The lifetime of tools and machines will be longer.
3. Heat-resistant coating: With highly heat-resistant HELICA/ALTIN coating, can be used for high-speed processing
4. Smooth and wide flute:Smooth and wide flute will remove the cuttings more easily.
5. High quality Raw Material: The raw material is used of high toughness, grain-sized carbon tungsten.
6. Polished surface treatment: With high polished surface treatment, reduce the friction coefficient could be reduced, the lathe efficiency could be improved, more production time could be saved
