Applications
This cutting tool is ideally suited for precisely turning external threads on components made from steel and stainless steel. The 60° full profile ensures the creation of exact metric thread forms, making it a highly practical choice for general mechanical engineering, fixture construction, and the manufacturing of complex turned parts.
Special features
The versatile RT315 carbide grade is equipped with a resilient PVD coating specifically tailored to the operational demands of the P15-P25 and M10-M25 material groups. This setup offers solid thermal stability and supports low-wear machining workflows. Supplied in a packaging unit of two pieces, it allows for swift tool changes and helps to maintain efficient inventory management during active production.
