Tool 100i156L015A

Small diameter work means higher spindle speeds and more heat at the cutting edge. The 100i156L015A handles that reality with TiAlSiN coating that stays stable when temperatures climb past what uncoated carbide can manage.

Four flutes keep chip load per tooth manageable even when feed rates drop to accommodate tight tolerances.
The 0.015" corner radius strengthens the cutting edge where small end mills typically fail first.
Right at the corner where maximum stress concentrates during entry and exit moves.
In steel and iron, that radius also improves surface finish by reducing the sharp transitions that leave tool marks.
The coating extends tool life in titanium and nickel alloys where work hardening and heat buildup typically shorten runs.
Ground to size on 5-axis equipment for consistent runout across the lot.
