Tool 220i250C

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 220i250C is a 0.25" diameter 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 TiB₂ coating provides a harder, more wear-resistant surface that helps prevent aluminum buildup on the cutting edge during extended profiling operations.
Ball nose geometry maintains consistent surface finish on curved profiles where stepover calculations become critical.
The coating extends tool life in production environments where frequent tool changes disrupt part consistency and setup time.
