BONET Tap Work Self Centering Chuck is available in 2-Jaw (SCT-2). These chucks are manufactured out of high quality materials. The bodies are made of alloyed high strength cast iron. All other parts are made of special steels which are properly tested chemically and physically before use. These parts are then suitably heat treated and pass through stringent quality control tests, which ensure long service life. STEEL BODY Chucks are also available. These chucks are mainly used to grip Taps & Yokes. The top portion of the jaws is kept soft, so that the fixture can be mounted by welding, drilling and tapping. Operating Key & Mounting Bolts are provided along with every Chuck. The movement of the jaws in single rotation is more than that of normal Self Centering Chuck.
