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.
