Tool 220i125C

Small diameter ball nose tools in aluminum face a double challenge. The tight radius concentrates heat while aluminum's tendency to weld creates built-up edge that ruins surface finish.

The 220i125C is a 0.125" diameter 2-flute solid carbide ball nose end mill designed for 3D profiling and contouring in aluminum, copper, and plastics.
The open 2-flute geometry provides maximum chip evacuation space around the curved cutting surface where engagement constantly changes.
TiB₂ coating adds a low-friction barrier that reduces aluminum adhesion while conducting heat away from the cutting edge.
This combination keeps the small ball nose running clean through complex contoured surfaces where chip packing would otherwise cause premature failure.
The geometry works particularly well in shallow stepover finishing passes where surface quality matters.
