Tool 220i500LC

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 220i500LC is a 0.5" 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 barrier layer that reduces aluminum pickup on the cutting edge.
This coating maintains lower friction at the tool-chip interface while providing wear resistance during extended profiling operations.
The ball nose geometry distributes cutting forces across the curved surface, reducing point loading that can cause chipping in interrupted cuts.
Heat dissipation improves with the open flute design, keeping temperatures manageable during the long tool paths typical in 3D work.
