tungsten carbide CNC Twist Drill Bits

Application

can be achieved from common steel, cast iron, copper, steel efficient cutting. 

Suitable for processing below HRC45 degrees the material.

.

Tool structure;

Optimize the structure and wave groove cutting edge.

Superior sharpness and strength, cutting discharged more smoothly.

138 degrees angle reduces the initial phase of drilling feed force, providing excellent self-centering capability, in order to improve the quality of hole machining.

 

Coating

ALTIN coating, not only has high-temperature oxidation resistance (800°),  but also has optimal performance in dry and high speed machining conditions.
