Powerful Roughing in Titanium and Inconel
The CNMG 120408-RSN RT130S is a high-performance indexable insert specifically engineered for roughing difficult-to-machine nickel-based alloys, heat-resistant super alloys, and titanium. The combination of the tough special grade RT130S (S05-S15) and an advanced PVD coating establishes stable workflows even under severe conditions such as heavy interrupted cuts.

Applications
Thanks to its extreme heat resistance and toughness, this turning insert is ideally suited for machining high-temperature alloys used in aerospace, medical technology, or the chemical industry. It shows its full strength during the roughing of forgings, casting skins, and in interrupted cuts, where conventional cutting materials quickly reach their limits.
Special features
The PVD high-performance coating effectively protects the cutting edge against abrasive wear and built-up edge formation, which is crucial when working with superalloys. The RSN chipbreaker ensures controlled chip breaking, thereby supporting reliable and economical operations with challenging special materials.
