Applications

This turning insert demonstrates its full potential in stainless steel machining, particularly for industries such as plant engineering, food technology, and medical manufacturing. It is engineered specifically for finishing operations where tight tolerances and excellent surface finishes are strictly required. The availability of multiple corner radii offers the necessary versatility for profile turning, facing, and longitudinal turning of complex workpiece contours.

Special features

Thanks to the advanced PVD coating, the RT255M grade provides high thermal stability, effectively reducing the typical edge wear encountered during stainless steel machining. The positive cut of the CCMT geometry, paired with the MF chipbreaker, ensures low cutting forces and reliable chip control, even under light interrupted cutting conditions. This creates a solid foundation for flexible and cost-effective solutions in modern manufacturing setups.
