High-performance cermet turning insert for flawless surfaces

For professional users who rely on high dimensional accuracy and excellent surface finishes during finishing operations, the Indexable insert - DNMG...-SF RTC+ proves to be a highly practical choice. The combination of a tough P05-P15 cermet substrate and a modern PVD coating effectively shields the cutting edge and supports reliable machining processes. Thanks to the sophisticated SF chipbreaker, a particularly light cutting action is achieved, which lowers machining forces and facilitates smooth turning tasks.

Applications

This coated cutting insert presents flexible application possibilities for the fine contour and longitudinal machining of steel and stainless steel components. It is primarily designed for continuous cutting conditions where tight tolerance requirements must be met consistently. Whether applied in demanding single-part manufacturing or productive series production, the tool strongly supports highly efficient workflows.

Special features

The premium RTC+ cermet grade features considerable thermal stability, which effectively counteracts the formation of built-up edges. Combined with the sharp SF geometry, the tendency for disruptive vibrations is noticeably decreased. This combination promotes a uniform wear behavior over the entire operational span, translating directly into reproducible and dependable component qualities.
