The style DSF is a 5-chaser diehead specially designed for use on turret and capstan lathes. It is quickly adaptable for straight, taper, right hand and left hand threads. The head is specially suitable for close to shoulder threads as the chasers move back from the shoulder immediately the dieheads opens.
The head is equipped with a lateral compensating float. Chasers and chaser blocks may be released simply by pulling up the handle and sliding back the cup unit. Chasers are interchangeable with DRF heads of the same capacity.
