High-performance turning with the TNMG...-PF RT315G indexable insert

The TNMG...-PF RT315G indexable turning insert opens up flexible application possibilities for professional finishing and medium machining. Equipped with a state-of-the-art CVD coating and manufactured from P15 carbide, it represents a well-thought-out solution for continuous cutting tasks. The negative triangular geometry with its specific PF chip former helps to achieve controlled chip breaking even in tough materials, thereby supporting process reliability in modern manufacturing.

Applications

This turning insert is specifically tailored for machining steel materials. It demonstrates its strengths as an effective problem-solver in chip control, particularly when finishing or medium-machining soft or tough steels. The primary focus is on continuous cutting conditions, where the cutting edge reliably absorbs constant loads.

Special features

The latest generation CVD coating combines high wear resistance with excellent thermal properties. Together with the specific PF geometry, the insert creates good conditions for improved surface qualities and supports efficient workflows by reducing chip-related interruptions. Available in three corner radii (0.4, 0.8, and 1.2 mm), the tool can be flexibly adapted to the required workpiece contour and feed rate.
