Tool 220i625LC

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 220i625LC is a 0.625" diameter 2-flute solid carbide ball nose end mill with TiB₂ coating 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 hard, low-friction surface that resists aluminum buildup while maintaining sharp cutting edges through temperature cycling.
Ball nose geometry distributes cutting forces across the spherical tip, reducing point loading that can cause chipping in interrupted cuts.
The coating extends tool life in continuous profiling operations where heat buildup typically degrades uncoated carbide performance.
