220 Series

Tool 220i188LFC

3D profiling in aluminum has a specific chip control problem. The curved contact surface changes engagement constantly, and aluminum tends to weld to the edge.

The 220 Series is a 2-flute solid carbide ball nose end mill for contouring and profiling in aluminum, copper, and plastics.
Two flutes maximize chip clearance at the cutting zone, giving aluminum chips room to exit before adhesion becomes a factor.
The TiB₂ coating on this 0.1875" diameter variant creates a hard, low-friction surface that resists aluminum buildup during extended profiling operations.
TiB₂ maintains its properties at the moderate temperatures typical in aluminum machining, extending tool life in applications where coated geometry matters more than raw speed.
The ball nose profile distributes cutting forces across a larger radius, reducing point loading during complex 3D paths.
