Achieved high-speed and high-efficient machining of high-hardened steel by reducing deflection.
Designed with thicker core diameter reduces the deflection of tool minimamly. High-speed and high-efficient machin-ing is possible until high-hardened steel until 70 HRC.

Thanks to low cutting force geometry, high-precision machiningis possible from semi-finishing to finishing.
The unique geometry keeps strength of cutting edges and reduce cutting force. Applicable fromsemi-finishing to finishing of high- precision machining.

High-precision machining with  long tool life is possible even in case the machining of high-hardened steel.
Cutting chips are evacuated smoothly from low speed cutting to high speed cutting.
