220 Series

Tool 220i188C

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 220 Series is a 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.
This 0.1875" diameter variant includes TiB₂ coating.
The coating runs harder than standard TiAlN while maintaining lower friction coefficients against aluminum.
Heat buildup stays controlled during the variable engagement that ball nose geometry creates in 3D work.
TiB₂ also resists the aluminum pickup that can build up on uncoated edges during longer profiling passes.
The open flute design handles the interrupted cuts typical in complex aluminum parts where material removal varies significantly along the tool path.
