Material specific HPX edge preparation
A straight cutting edge reduces build-up and chipping on cutting edge and margin land. 

Material-specific HPX drill point
Patented HPX point provides excellent self-centering capabilities, reduces thrust, and enables precise center chip formation.

Material-specific HPX margins 
2 margin lands provide stability, reduce friction.

The HPX drill design
Up to 3 times higher cutting parameters, saving machining time and freeing up capacity.

Ultra-high polished chip flutes reduce friction, improve chip evacuation, and increase tool life.

A continuous chip-flute cross-section reduces vibrations and reduces cutting edge chipping. 

Standard MQL backend

Up to 8xD drilling

Corner Chamfer - Build-in cutting edge corner protection, reduces chipping and extends tool life.

140˚ point angle – For ideal cutting conditions.  Perfect for pilot drilling of deep holes.

2 margin lands for stability and less friction.

Straight cutting edge – Reduces build-up and chipping on cutting edge and margin land.

 

Lower forces, even better reliability

The HPX drill produces consistently higher tool life in steel than competitive tools, even when feeds and speeds are significantly increased.

Special gashing on the HPX drill improves the chip formation and curls a smaller chip. The material specific HPX point geometry creates significantly lower cutting forces, which works great for machines with lower spindle capabilities, unstable cutting conditions, or unstable workpiece clamping. A continuous cross section makes the HPX drill more resistant against tool breakage, and the ultrahigh polished chip flutes ensure superior chip evacuation.
