Applications
This thread turning insert is designed for producing right-hand external threads with a 55-degree flank angle, commonly used for Whitworth or BSP pipe threads. It is widely applied in mechanical engineering, maintenance, and general turning operations.
Special features
The PVD coating of the RT315 carbide grade enhances wear resistance and promotes efficient chip control during universal applications. The partial profile design reduces the need for tool changes, as various pitches can be machined without changing the insert.
