Tool 220i375LC

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 220i375LC is a 0.375" 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 cuts.
This coating maintains sharp cutting edges longer in soft, sticky materials where uncoated tools typically see rapid edge degradation from material adhesion.
The ball nose geometry handles complex 3D surfaces while the open flute design manages the variable chip loads inherent in sculptured surface work.
