Tool 220m040LC
Large diameter profiling cuts in aluminum present heat and chip adhesion challenges. The extended cutting edge contact generates more heat, and aluminum's tendency to weld increases with temperature.
- The 220m040LC is a 4" diameter 2-flute solid carbide ball nose end mill designed for 3D profiling and contouring in aluminum, copper, and plastics.
- The wide 2-flute geometry provides maximum chip evacuation space, critical when the large cutting diameter generates higher chip volumes.
- TiB₂ coating adds a thermal barrier that reduces heat transfer to the substrate while providing a low-friction surface that resists aluminum adhesion.
- The coating maintains its properties at the elevated temperatures common in heavy aluminum removal operations.
- Two flutes balance surface finish requirements with chip clearance needs on curved profiling paths where engagement varies continuously.
