100 Series

Tool 100i625L015A

Most shops know the sound of an end mill giving up mid-cut. The 100 Series 4-flute is built to avoid that conversation with steel, iron, titanium, and nickel alloys.

Four flutes keep chip load balanced across the cutting edge, which matters when you're holding tight tolerances through extended runs.
The TiAlSiN coating handles the heat buildup that comes with interrupted cuts in harder materials.
Aluminum, silicon, and nitrogen create a barrier that lets the carbide underneath do its job longer.
That 0.015" corner radius takes the stress concentration off the cutting edge, spreading wear across a broader area instead of concentrating it at a sharp point.
In profiling operations on steel or slotting through titanium, this geometry combination keeps cutting forces predictable.
The result is parts that measure the same at the end of the run as they did at the start.
