Tool 150i625L006A

Chatter marks and poor surface finish plague semi-finishing operations in harder steels. Five flutes distribute the cutting load across more edges.

The 150i625M030A runs higher table feeds without overloading individual cutting edges.
TiAlSiN coating handles the elevated temperatures that come with increased metal removal rates in steel, iron, titanium, and nickel alloys.
The aluminum content in this coating maintains hardness at higher cutting temperatures better than standard TiN.
The 0.03" corner radius strengthens the cutting edge where it contacts the workpiece.
Sharp corners chip under load in interrupted cuts and harder materials.
This geometry extends tool life in semi-finishing operations where you need decent surface finish but still want reasonable cycle times.
