220 Series

Tool 220m120C

Large diameter ball nose work in aluminum creates heat buildup at the extended cutting edge. More material contact means more friction, and aluminum's thermal conductivity can't always keep up with the heat generation at a 12" cutting diameter.

The 220m120C is a 12" cutting diameter, 2-flute solid carbide ball nose end mill for contouring and profiling in aluminum, copper, and plastics.
The TiB₂ coating reduces friction at the tool-chip interface, helping manage the thermal load that comes with this cutting diameter.
Two flutes maintain maximum chip clearance even when working large curved surfaces where chip evacuation becomes critical.
The coating also provides a harder surface that resists the adhesion tendencies of aluminum while maintaining the sharp edge geometry needed for smooth surface finishes in 3D profiling operations.
