Tool 220i156LFC

Small diameter ball nose work in aluminum creates heat concentration problems. The limited cutting edge length and continuous curved contact generate friction that builds up quickly in the confined cutting zone.

The 220i156LFC is a 0.1563" diameter 2-flute solid carbide ball nose end mill for 3D profiling and contouring in aluminum, copper, and plastics.
The TiB₂ coating provides a low-friction surface that reduces aluminum adhesion while conducting heat away from the cutting edge.
Two flutes keep chip load per tooth higher at small diameters, maintaining efficient cutting action while providing maximum chip evacuation space around the ball nose geometry.
This prevents the chip packing that typically causes built-up edge formation in aluminum profiling operations.
