Tool 220i250LC

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 220i250LC is a 0.25" diameter 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 TiB₂ coating adds a hard, low-friction surface that resists aluminum buildup during extended profiling operations.
This coating maintains sharp cutting edges longer when working curved surfaces where heat builds from constant tool-workpiece contact.
The ball nose geometry follows complex contours without leaving scallop marks between passes.
Chip evacuation stays consistent even as the effective cutting diameter changes through the tool path.
