220 Series

Tool 220m040C

Large diameter aluminum profiling creates heat concentration problems. A 4" ball nose generates significant cutting forces, and aluminum's thermal conductivity means heat builds up faster than it dissipates at the tool interface.

The 220m040C is a 2-flute solid carbide ball nose end mill designed for heavy aluminum contouring work.
The TiB₂ coating provides a harder, more chemically inert surface that resists aluminum adhesion while maintaining thermal stability under the heat loads typical of large diameter operations.
Two flutes keep chip load per tooth high enough for effective cutting while maintaining maximum evacuation space around the curved cutting zone.
The geometry works in aluminum, copper, and plastics where chip welding and heat buildup limit tool life in traditional configurations.
