Tool 100i250L030A

Quarter-inch end mills take a beating in production work. The 100i250L030A handles that reality with four flutes and a TiAlSiN coating designed for consistent performance in steel, iron, titanium, and nickel alloys.

The four-flute geometry spreads chip load evenly, which matters when you're running multiple parts per setup.
Even distribution means each cutting edge sees predictable loads, reducing the wear variation that turns good parts into scrap halfway through a run.
The 0.030" corner radius strengthens the cutting edge while maintaining sharpness where it counts.
TiAlSiN coating runs cooler than uncoated carbide in these tougher materials.
Lower cutting temperatures mean more stable tool life, especially in interrupted cuts and variable depth operations where heat cycling would otherwise accelerate wear.
Ground in-house on 5-axis CNC equipment for consistent runout and edge prep.
Solid carbide.
Made in the USA.
