Applications
This threading insert is an excellent choice for challenging internal thread turning in mechanical engineering, toolmaking, and general manufacturing environments. Thanks to the versatile RT315 cutting grade, the indexable insert provides great flexibility when working with frequently changing materials such as steel, stainless steel, non-ferrous metals, and various special alloys. Its sophisticated design supports robust production workflows where profile fidelity and consistent removal rates are a priority.
Special features
The ground 60° full profile enables the manufacturing of dimensionally accurate threads in a single continuous machining operation, cutting out the complete thread profile effectively. Furthermore, the high-strength PVD coating (P15-P25 & M10-M25) ensures excellent wear resistance alongside high thermal stability at the cutting edge. This specific combination lays the foundation for seamless workflows and consistent thread quality across varying cutting conditions.
