Tool 170i625M030A

Maintaining edge integrity while pushing feed rates in harder alloys requires distributing the cutting load. Seven flutes on this 0.625" end mill spread the work across more cutting edges, reducing chip load per tooth while enabling aggressive table feeds in steel, iron, titanium, and nickel alloys.

The TiAlSiN coating extends tool life in these demanding materials through enhanced heat resistance and reduced friction at the cutting interface.
Higher aluminum content in this coating formulation performs better than standard TiAlN when temperatures climb during interrupted cuts or work hardening scenarios.
The 0.03" corner radius strengthens the cutting edge compared to sharp corner geometry while maintaining good entry characteristics.
This radius prevents chipping on entry and extends edge life in tougher grades of steel and superalloys where edge strength matters more than absolute sharpness.
