For internal threading, it is always recommended to use the largest diameter shank possible for maximum rigidity which will result in the best quality thread for being machined. Cutting large pitch threads with small toolholders can cause vibration and poor quality threads.
Our range of single point threading tool holders for lathe screw cutting is compatible with all major threading inserts (with the exception of Sandvik). We stock screw clamp or top clamp threading tools.
