Tool 200m120LC

Aluminum punishes the wrong tool fast. Chip welding, built-up edge, a finish that looks like the tool dragged instead of cut. If you've seen it, the setup wasn't right. Usually it starts with the cutter.

The 200m120LC is a 12" diameter 3-flute solid carbide end mill built specifically for aluminum, copper, and plastics.
Three flutes keep chip load lower per tooth while maintaining feed rate.
That's the actual mechanism behind built-up edge prevention, the mechanism, not a geometry preference.
High helix promotes chip evacuation before heat or adhesion becomes a factor.
TiB₂ coating handles the demanding passes where uncoated carbide would struggle with work hardening or abrasive fillers.
The R0.2" corner radius strengthens the cutting edge while reducing stress concentrations that lead to chipping on interrupted cuts.
