220 Series

Tool 220m050FC

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 5" diameter variant adds a hard, slick surface that reduces aluminum's tendency to build up on the cutting edge during extended profiling operations.
Ball nose geometry maintains constant contact with curved surfaces while the open flute design prevents chip packing in tight radii.
The coating's low friction properties become particularly useful when maintaining surface finish across varying engagement angles in 3D work.
