Optimized design of inserts for maximum drilling efficiency.
Excellent cutting performance and chip control due to the optimized geometry and chip breaker of both inserts, central & peripheral.
2 different inserts, optimized for the central and peripheral insert locations in order to maximize cutting tool life.
3 coolant hole system
The center coolant hole system helps prevent wear on the chip pocket of the central insert and improves chip control.
The optimized shape of the flute increases the rigidity of the drill body and improves chip evacuation.
