220 Series

Tool 220i313LC

3D profiling in aluminum has a specific chip control problem. The curved contact surface changes engagement constantly, and aluminum tends to weld to the edge.

The 220 Series is a 2-flute solid carbide ball nose end mill for contouring and profiling in aluminum, copper, and plastics.
Two flutes maximize chip clearance at the cutting zone, giving aluminum chips room to exit before adhesion becomes a factor.
The 220i313LC features TiB₂ coating to reduce aluminum buildup on the cutting edge.
TiB₂ creates a harder, lower-friction surface that resists the welding tendency of aluminum during extended profiling operations.
The 0.3125" cutting diameter provides good surface finish on curved surfaces while maintaining reasonable rigidity for consistent dimensional control.
This geometry works well for sculptured surfaces, mold cavities, and complex contours where chip evacuation matters more than feed rates.
