Tool 100m050A

Large diameter end mills tend to chatter. Five inches of cutting diameter amplifies every vibration, every imbalance in the setup. The 100m050A addresses this with four flutes that distribute cutting forces more evenly than three-flute designs, reducing the amplitude of vibrations that kill surface finish in steel and iron.

The TiAlSiN coating handles the heat buildup that comes with this cutting diameter.
When you're removing material at this scale, temperatures climb fast enough to break down uncoated carbide edges.
The coating acts as a thermal barrier, keeping the substrate stable through extended cuts in titanium and nickel alloys where heat generation is inevitable.
Corner radius holds at R0.1", enough to prevent chipping without compromising corner definition.
In heavy roughing operations, that radius distributes stress across more edge area than a sharp corner can handle.
