220 Series

Tool 220i188FC

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 model features TiB₂ coating for additional heat resistance and lubricity.
The coating reduces friction between the cutting edge and aluminum workpiece, helping prevent the built-up edge formation that causes surface finish problems.
TiB₂ maintains its properties at the moderate temperatures generated in aluminum machining, extending tool life without adding significant thickness to the cutting edge geometry.
The ball nose geometry follows complex contours while maintaining consistent surface finish across varying engagement angles.
