Tool 100i156M030A

Small diameter work puts stress on the cutting edge in ways that larger tools never see. The 100i156M030A handles that stress through geometry and coating designed specifically for the challenges of sub-quarter-inch machining in steel, iron, titanium, and nickel alloys.

Four flutes keep chip load balanced even when working at the higher spindle speeds that small diameter end mills require.
TiAlSiN coating adds a thermal barrier that matters more in small tools because heat buildup happens faster when there's less carbide mass to absorb it.
The 0.03" corner radius strengthens the cutting edge without compromising corner definition.
Critical when you need both durability and precision in profiling operations.
In steel and iron, this combination of flute count, coating, and corner geometry delivers the run-to-run consistency that keeps small diameter work predictable.
