3/8" 4FL .020CR CARBIDE END MILL

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