Tool 190i750L030A

Hardened steel finishing demands control over both surface quality and tool life. The 190i750L060A addresses this with nine flutes and TiAlSiN coating engineered for extended performance in demanding alloys.

Nine flutes means each tooth removes minimal material per revolution.
That light chip load is what generates the finish quality in steel, iron, titanium, and nickel alloys.
The R0.06" corner radius strengthens the cutting edge while maintaining sharpness for precise surface generation.
TiAlSiN coating provides thermal stability and wear resistance when cutting harder materials at the high RPMs this geometry requires.
The aluminum content in the coating forms a protective oxide layer during cutting, extending tool life in heat-generating applications.
Requires rigid fixturing and appropriate speeds.
Not intended for roughing operations or heavy material removal.
