120 Series

Tool 120m200A

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

Ball nose geometry at 20" 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 20" diameter variant carries TiAlSiN coating to extend tool life in demanding ferrous applications.
The coating's aluminum content provides oxidation resistance at elevated cutting temperatures, while the silicon component reduces friction during chip formation.
The multilayer structure maintains sharp cutting edges longer than uncoated carbide in work-hardening materials like stainless steel and high-temperature alloys.
The ball nose geometry eliminates witness lines common with flat end mills on sculptured surfaces.
