220 Series

Tool 220i500C

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.
The TiB₂ coating on this 0.5" diameter model adds a low-friction surface that reduces aluminum pickup during extended profiling operations.
Ball nose geometry maintains consistent surface finish across compound curves where spindle tilt varies.
The coating works particularly well in aluminum because it stays chemically inert under the heat conditions typical in 3D work, where constant direction changes prevent steady-state thermal management.
