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 well-thought-out solution. The tool unites a tough P05-P15 cermet substrate with a modern PVD coating. This construction effectively protects the cutting edge against wear and supports reliable machining processes. The sophisticated SF geometry facilitates a particularly light cut, which lowers machining forces and enables smooth chip evacuation during continuous turning tasks.

Applications
This coated cutting insert shows its strengths in 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 safely met. Whether in demanding single-part manufacturing or productive series production, the tool opens up flexible application possibilities for highly efficient operations.
Special features
The RTC+ cermet grade features high thermal stability, which effectively counteracts the formation of built-up edges. Together with the sharp SF chipbreaker, the tendency for disruptive micro-vibrations is significantly reduced. This results in consistent wear behavior over the entire tool life, directly translating into reproducibly high component quality and more profitable workflows.
