Applications

This grooving insert specializes in hard turning and is primarily used for machining hardened steels. Due to its high edge stability, the fine-grain CBN grade is excellently suited for grooving under continuous load as well as in interrupted cuts. It is designed for industrial use and can be seamlessly operated with compatible tool holders from the MGM./MRM. system.

Special features

The MGGN ...-CBN RTC20 impresses with its targeted alignment towards difficult-to-machine, hard materials. By utilizing a fine-grained CBN cutting edge, it provides reliable wear resistance even under shock loads. With widths of 2 mm or 3 mm, precise grooves and recesses can be achieved, making the insert an important component in professional turning operations.
