MC6125 & MC6115 are the first recommendations for steel turning and are suitable for a wide range of continuous through to intermittent machining applications. By improving the existing technology, wear and fracture resistance and cutting edge stability have been dramatically increased. Machine tools have become more powerful and efficient, so to meet the demand of higher cutting speeds and to improve their machining efficiency, the MC6100 series of grades have been developed. To respond to these demands for high efficiency, and also for use on conventional applications, MC6115 and MC6125, the latest CVD coated grades have been developed for turning steels at high speeds. They also provide improved cutting edge stability.
