120 Series

Tool 120i250A

Complex 3D surfaces in harder alloys generate heat that can break down tool edges and degrade surface finish.

Ball nose geometry at 0.25" cutting diameter follows contoured surfaces without leaving flat-bottomed transitions.
The rounded tip produces smooth transitions on contoured surfaces and mold profiles while the TiAlSiN coating provides thermal barrier protection during extended cuts in heat-generating materials.
Three flutes balance chip clearance with cutting engagement on curved geometry.
The 0.25" cutting diameter handles detailed features and tight radii common in die work and aerospace components.
The coating extends tool life in titanium and high-temperature alloys where uncoated carbide typically fails from thermal stress.
Heat resistance becomes critical when climb milling complex surfaces where cutting loads vary continuously.
