220 Series

Tool 220m120LC

Heavy aluminum removal in 3D profiling generates significant heat buildup at the cutting edge. The curved contact geometry creates inconsistent chip loads that can lead to edge welding and premature tool failure.

The 220m120LC is a 2-flute solid carbide ball nose end mill designed for contouring and profiling in aluminum, copper, and plastics.
The 12-inch cutting diameter handles large radius features while maintaining surface finish control.
Two flutes provide maximum chip clearance in the curved contact zone, preventing chip packing that leads to heat generation.
The TiB₂ coating adds a thermal barrier at the cutting edge.
This coating reduces the tendency for aluminum to adhere to the carbide substrate during extended profiling operations.
The combination of open flute geometry and thermal protection extends tool life in continuous 3D machining applications.
