Stabilizer 2.0 family of end mills raises the bar in high performance milling by incorporating a patented continuously varying asymmetrical geometry which creates smooth chatter free milling. This configuration, along with a specially engineered flute shape, allow for doubled feed rates of the original Stabilizer. The ST430.2 series are specifically designed for machining steels, alloy steels, copper alloys and cast iron. The ST440.2 series are specifically designed for machining ISO-S materials like stainless steels, steels over 42 Rc, titanium and Inconel. These mills feature an AlTiN coating that offers high heat resistance and superior abrasion resistance to maximize tool life.
