100 Series

Tool 100i500Z060A

Most shops know the feeling. Three hours into a run and the surface finish starts to drift. The 100 Series 4-flute end mill with TiAlSiN coating is built to hold that finish steady in steel, iron, titanium, and nickel alloys.

Four flutes keep chip load consistent across the cut.
The TiAlSiN coating adds a thermal barrier that matters when you're pushing feed rates in harder alloys or taking deeper cuts in steel.
Heat buildup is what kills edge life early, and this coating extends that thermal threshold without making the tool brittle.
The R0.06" corner radius strengthens the cutting edge where it needs it most.
Sharp corners chip under interrupted cuts, but this radius maintains strength while preserving the corner definition your parts need.
