Tool 190i1000M060A

Surface finish requirements in hardened steel can make or break a job. The 190 Series puts nine flutes on a one-inch diameter specifically to minimize chip load per tooth while maintaining reasonable feed rates.

Each tooth takes a light chip, keeping heat generation low while producing the surface quality hardened steel applications demand.
That light engagement reduces heat generation and tool deflection while producing the surface quality hardened steel applications demand.
The R0.125" corner radius distributes cutting forces more evenly than sharp corners, extending tool life in interrupted cuts.
TiAlSiN coating handles the thermal cycling that comes with intermittent engagement in steel, iron, titanium, and nickel alloys.
The aluminum content forms a protective oxide layer at cutting temperatures.
Requires high spindle speeds and minimal radial engagement.
