Suited for longitudinal and face turning, CoroTurn® 300 uses iLock™ interface for stable insert clamping. System securely locks insert in place to prevent cutting forces from affecting tool position and provides tool accuracy within ±.002 in. Eight-edged inserts are available in grades GC4325 and GC4315 featuring Inveio™ coating, a uni-directional crystal orientation for wear resistance and extended tool life. Coolant from above controls chip breaking, while under coolant controls temperature.
