120 Series

Tool 120i125LA

Micro milling operations in hard alloys generate heat that breaks down uncoated carbide at small diameters.

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 provides thermal barrier protection at the 0.125" cutting diameter where heat concentration becomes critical.
The aluminum-silicon nitride layer maintains hardness at elevated temperatures while reducing chemical reaction with workpiece materials.
This coating extends tool life in interrupted cuts and allows higher surface speeds in titanium and nickel applications.
