Tool 100i156LA

Small diameter end mills break. That's the reality when you're running production with 0.156" tooling in steel and titanium. The 100i156LA addresses this with geometry and coating engineered for smaller cross-sections.

Four flutes keep cutting forces balanced even when there's not much carbide to work with.
Each flute takes a smaller bite, which matters more as diameter decreases.
The ratio of cutting force to tool strength gets worse fast on small tools.
TiAlSiN coating runs cooler than uncoated carbide, giving you thermal protection when heat has nowhere to go in tight quarters.
The R0.004" corner radius strengthens the cutting edge without compromising corner definition.
In profiling operations on steel and nickel alloys, that small radius prevents the micro-chipping that kills small end mills early.
