High-performance indexable insert for special materials
The DNGG...-SF RT110S is a precision-ground indexable insert specifically developed for finishing heat-resistant super alloys and demanding special materials. Equipped with a wear-resistant PVD-TiAlSiN coating on an S10 substrate, it supports efficient turning operations with high process reliability. The geometry with a 55° corner angle and the SF chipbreaker enables excellent surface qualities under continuous cutting conditions. Professional users benefit from a well-thought-out solution that is available in different corner radii (0.4 mm and 0.8 mm), opening up flexible application possibilities in industrial metalworking.

Applications
This high-precision insert is designed for profile turning and finishing of difficult-to-machine materials. It proves its worth particularly when machining complex components made of super alloys, where exact surface finishes and dimensional accuracy are required. The continuous cut creates ideal conditions for smooth tool engagement and consistent machining results in professional manufacturing.
Special features
The combination of the tough S10 carbide and the temperature-resistant PVD-TiAlSiN coating effectively protects the cutting edge from abrasive wear. The specially designed SF geometry supports chip breaking during finishing operations and contributes significantly to the prevention of built-up edges. With the available variants, workflows can be precisely adapted to the respective workpiece contour.
