Tool 190i750L060A

Hard materials punish sharp corners and thin edges. The R0.06" corner radius on this one-inch diameter end mill distributes cutting forces across more carbide, extending tool life in steel, iron, titanium, and nickel alloys.

Nine flutes means each tooth removes minimal material per revolution.
That geometry demands adequate spindle speed but delivers the surface finish that secondary operations typically provide.
The TiAlSiN coating handles the heat buildup from those high cutting speeds while maintaining the sharp edge geometry that nine-flute tools depend on.
Corner radius also prevents the edge chipping that kills finishing tools in interrupted cuts.
The coating extends into blend radii where stress concentrates.
Works in materials up to 45 HRC where conventional high-speed steel tools lose their edge.
