Tool 220i156C

Small diameter ball nose work in aluminum creates heat concentration problems. The reduced mass at the cutting edge struggles to dissipate heat, and aluminum's tendency to weld becomes more pronounced at smaller tool sizes.

The 220i156C is a 0.1563" diameter 2-flute solid carbide ball nose end mill with TiB₂ coating for 3D profiling and contouring 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 fine detail work.
Two flutes create maximum chip evacuation space around the small ball nose form, preventing chip packing that leads to heat buildup and edge welding.
The geometry balances cutting efficiency with the clearance requirements of curved surface machining.
Works effectively in both roughing and finishing operations where surface quality matters.
