Professional roughing with CVD-coated P10 carbide

The CNMG...-PR RT215+ turning insert convinces as a reliable and powerful solution for the roughing of steel. By combining a strong negative 80° insert shape with the advanced RT215+ grade, this cutting tool is specifically designed for high material removal rates during full-cutting operations. The specialized PR chipbreaker, combined with continuous cutting conditions, supports smooth chip evacuation and ensures efficient, predictable workflows in metal machining.

Applications

This CNMG insert is oriented towards robust longitudinal and face turning of steel materials. Thanks to the P10 classification and its design for continuous cuts, it shows its strengths primarily in stable full-cutting scenarios, where a consistently high machining performance is required.

Special features

The wear-resistant CVD-coated carbide effectively protects the cutting edge against rapid abrasion, maintaining the dimensional accuracy of the workpiece over an extended period. The strong 80° corner provides sufficient stability to confidently absorb the high thermal and mechanical loads encountered during roughing. With four usable cutting edges, this variant also represents a highly economical choice for professional turning operations.
