100 Series

Tool 100i500Z040A

Most shops know the feeling. End mill starts strong, then edge quality falls off a cliff somewhere mid-run. The 100 Series builds consistency into every cut by spreading chip load across four flutes, so each edge sees the same work cycle after cycle.

The TiAlSiN coating handles the heat buildup that comes with interrupted cuts in steel and iron.
When you're running production volumes, that thermal barrier keeps the carbide substrate stable even when surface temperatures spike.
The R0.04" corner radius takes stress concentration off the cutting edge during entry and exit.
Particularly useful in slotting operations where shock loading can chip a sharp corner.
Four flutes mean each one works a quarter as hard.
In titanium and nickel alloys where work hardening is always a concern, that load distribution translates directly to tool life predictability.
