Applications

The TNMG insert is specifically tailored for the medium machining of cast iron. It offers a practical solution for standard longitudinal, facing, and profiling turning tasks. Due to the high toughness of the substrate, the tool easily masters demanding conditions such as heavily interrupted cuts, while providing consistent process reliability in industrial environments.

Special features

The CVD-coated K10-K20 carbide of the RT150K grade convinces with exceptional thermal resilience and wear resistance. The triangular negative shape provides a total of six usable cutting edges, leading to a significant reduction in tooling costs. The integrated chipformer contributes to efficient chip evacuation and preserves the cutting material.
