Applications

This cutting insert is geared towards universal turning in mechanical engineering and stainless steel fabrication. It opens up flexible application possibilities in medium-duty cutting conditions. Typical applications include facing, longitudinal turning, and contour machining of stainless steel components.

Special features

The PVD coating of the RT255M grade, combined with the positive TCMT basic shape, promotes reduced cutting forces and even chip evacuation. This protects the workpiece and supports a smooth machining process. The M20-M30 substrate offers a robust core that brings thermal stability for demanding cutting tasks.
