Tool 220i375C

Aluminum buildup on the cutting edge kills surface finish in 3D profiling work. The material's tendency to adhere increases with heat, and curved tool paths generate inconsistent chip loads that create hot spots.

The 220i375C is a 0.375" diameter 2-flute solid carbide ball nose end mill designed for contouring and profiling in aluminum, copper, and plastics.
The TiB₂ coating provides a low-friction surface that reduces aluminum adhesion while maintaining the sharp edge geometry needed for clean entry and exit in curved tool paths.
Two flutes create maximum chip evacuation space around the ball nose radius, preventing chip packing that leads to heat buildup and work hardening.
The coating also extends tool life in abrasive plastics while maintaining the thermal properties needed for aluminum's heat management requirements.
