220 Series

Tool 220m200LC

Large diameter ball nose work in aluminum creates heat concentration at the cutting edge. More material contact means more friction, and aluminum's thermal conductivity can't always keep up with the heat generation at 20-inch diameters.

The 220m200LC is a 2-flute solid carbide ball nose end mill designed for heavy aluminum profiling and contouring operations.
The open flute geometry maintains chip evacuation even with the increased material contact of a 20-inch cutting diameter.
TiB₂ coating provides thermal barrier properties that reduce heat buildup at the tool-workpiece interface while maintaining the sharp edge geometry aluminum requires.
Two flutes balance cutting forces across the large diameter while maximizing chip clearance in curved surface operations.
The coating extends tool life in continuous cutting applications where heat accumulation typically causes premature wear.
