120 Series

Tool 120i313A

3D profiling and contouring demand a cutter that follows the surface without leaving a flat-bottomed step.

Ball nose geometry at 0.3125" 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.
This 5/32" diameter variant carries TiAlSiN coating for extended tool life in ferrous materials.
The coating's aluminum content provides oxidation resistance at elevated cutting temperatures, while the silicon addition maintains hardness under thermal stress.
The coating reduces built-up edge formation when machining steels and allows higher surface speeds in titanium applications.
The ball nose geometry eliminates witness marks on complex surfaces where flat end mills leave steps between passes.
