The style DBS diehead has been specially developed for use with single-spindle automatic screw machines. The outstanding success of this head is due to its rugged simplicity and its power to maintain precision under the most severe production conditions. Two adjusting screws provide simultaneous diameter adjustment, eliminating individual chaser adjustment. Close to shoulder threading is a feature of design. Right hand and left hand threads cut with the same set of chasers, different chaser blocks only being necessary.
