Tool 220i313C

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 220i313C is a 0.3125" diameter 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 adds a barrier layer between the carbide substrate and workpiece material.
This coating reduces the tendency for aluminum to stick to the cutting edge during extended profiling operations where heat builds up in the contact zone.
The ball nose geometry maintains consistent surface finish across complex curved profiles where conventional end mills would leave witness marks.
