Namco Dieheads - Style DS
 Designed for use on Turret and Capstan lathes, the DS Diehead is especially recommended for threading close to the shoulder and into undercuts. Its unique self-opening action allows chasers to move back from the shoulder immediately the Diehead opens. Chasers and blocks are interchangeable between DS and DR Dieheads of the same capacity.
Ideal for:
- Parallel and taper threads
- Right and left hand threads
