It’s built for a wide range of users—from engineers and buyers to tradespeople and hobbyists—delivering precise thread forms and clean surfaces with repeatable performance.
The system uses ground-profile inserts for high precision and excellent performance, enabling reliable results even at demanding cutting parameters.
