Specifications

Applied to wood drilling;excellent for high rotary speed machining;sharp edge and high impact resistance;long service life.

 

Advantages for the Longlife Throughhole ("V" point) drill:

1.Better for machine tools' high rotary speed,and high or low speed cutting.

2.The second main cutting edge adopting Achimedean Spiral Principle,the edge sharper and its impact resistance higher.

3.The design of two back angles and several cutting edeges to disperse cutting force,to reduce edge crack and inactiviation.

4.Service life three times longer than the conventional throughhole drill.
