100 Series

Tool 100m030LA

Heavy roughing cuts in steel generate heat. The kind that turns cutting edges blue and sends tools to the scrap bin early. The 100 Series with TiAlSiN coating handles those thermal spikes by forming a protective aluminum oxide layer at cutting temperatures above 800°C.

Four flutes keep chip load consistent across the full 3" cutting diameter.
When you're taking 0.5" depth cuts in 4140 or removing stock from titanium forgings, that load distribution prevents any single flute from carrying too much heat.
The R0.1" corner radius reinforces the cutting edge where it meets the workpiece.
Enough to resist chipping without compromising edge sharpness in finishing passes.
TiAlSiN performs in interrupted cuts on cast iron and maintains hardness in nickel alloy applications where uncoated carbide loses its edge.
The coating stays put when the heat builds up.
