Tool 220m100LC

Large diameter ball nose work in aluminum creates heat concentration problems. A 10-inch cutting diameter generates significant surface speeds even at conservative RPMs, and aluminum's tendency to weld becomes more pronounced as temperatures rise.

The 220m100LC is a 2-flute solid carbide ball nose end mill designed for heavy contouring and 3D profiling in aluminum, copper, and plastics.
The open flute geometry maintains chip evacuation across the full 10-inch diameter, preventing chip packing that leads to heat buildup.
TiB₂ coating provides a hard, low-friction surface that resists aluminum adhesion while conducting heat away from the cutting edge more effectively than uncoated carbide.
Two flutes balance cutting forces while maximizing chip clearance space.
This becomes critical at larger diameters where chip volume increases substantially.
