Applications
This threading insert is excellently suited for cutting external threads on turned parts made of steel and stainless steel. Thanks to the 60° full profile, precise metric threads can be achieved in general machining, mechanical engineering, and when working with complex workpiece contours.
Special features
The universal RT315 carbide grade features a wear-resistant PVD coating specifically matched to the requirements of the P15-P25 and M10-M25 ranges. This enables flexible use while maintaining high thermal stability. The packaging unit of two pieces provides an excellent basis for efficient inventory management and reliable production processes.
