Tool 100i250S015A

Quarter-inch end mills take a beating in production work. The 100i250S015A is designed to take that beating consistently, shift after shift. TiAlSiN coating handles the heat that builds up in steel and iron when you're holding feeds and speeds for volume work.

Four flutes keep chip evacuation predictable across the cut.
When you're profiling or side milling steel components, that predictable evacuation prevents the chip welding that kills tools early.
The R0.015" corner radius distributes cutting forces away from the sharp corner where most fractures start, extending tool life in interrupted cuts and entry conditions.
TiAlSiN coating maintains hardness at temperatures where uncoated carbide starts to soften.
In titanium and nickel alloys where heat generation is unavoidable, that hardness retention translates to consistent surface finishes part to part.
