120 Series

Tool 120i125A

Small diameter ball nose end mills face accelerated wear in hard ferrous materials. Heat buildup concentrates at the tip radius where cutting speeds are lowest.

Ball nose geometry at 0.125" cutting diameter follows contoured surfaces without leaving flat-bottomed transitions.
The rounded tip produces smooth transitions on contoured surfaces and mold profiles.
Three flutes balance chip clearance with cutting engagement on curved geometry.
TiAlSiN coating adds thermal barrier protection at the critical tip radius where heat concentration is highest.
The aluminum content in the coating maintains hardness at elevated temperatures while silicon reduces friction during the cut.
At 0.125" diameter, this cutter handles detailed 3D profiling work where surface finish matters.
The coating extends tool life in interrupted cuts common to mold and die applications.
