100 Series

Tool 100i125M030A

Small diameter work in steel demands precision you can count on. The 0.125" diameter 100 Series puts four flutes to work distributing chip load where tolerances matter most.

TiAlSiN coating handles the heat buildup that comes with smaller end mills running in steel and iron.
The coating's aluminum content forms a protective oxide layer during cutting, extending tool life when thermal cycling would otherwise break down the edge.
Four flutes keep individual chip loads manageable even when pushing feed rates in slotting operations.
The R0.03" corner radius strengthens the cutting edge without sacrificing detail work.
That radius prevents the sharp corner chipping that kills small end mills in interrupted cuts, while still maintaining the edge definition needed for precision features in steel, iron, titanium, and nickel alloys.
