Tool 100m120A

Large diameter cuts in steel expose every weakness in your setup. Deflection, chatter, and heat buildup all scale up with size, and a 12" end mill amplifies every problem. The 100m120A handles these challenges through geometry designed for stability rather than speed.

Four flutes keep chip load consistent across the full 12" sweep.
That even distribution prevents the hot spots that typically develop in large diameter operations on steel and iron.
The TiAlSiN coating adds thermal barrier properties that matter more at this scale - when you're removing this much material, heat management becomes the limiting factor in tool life.
The R0.2" corner radius strengthens the cutting edge where stress concentrates most.
In heavy roughing cuts on titanium and nickel alloys, that radius prevents the micro-chipping that kills tools prematurely.
