Tool 220i156LC

Small diameter ball nose work in aluminum presents edge wear challenges. The 0.1563" cutting diameter concentrates heat at a smaller contact patch, and aluminum's tendency to adhere increases as cutting speeds rise to maintain surface finish quality.

The 220i156LC is a 2-flute solid carbide ball nose end mill designed for 3D profiling and contouring in aluminum, copper, and plastics.
The TiB₂ coating provides a harder, more chemically inert surface that resists aluminum buildup while maintaining the sharp edge geometry needed for fine detail work.
Two flutes create maximum chip evacuation space around the curved ball nose profile, preventing chip packing in tight radius cuts.
The open flute design keeps cutting forces lower during direction changes common in complex 3D toolpaths.
