We deliver our 1250mm 4-jaw independent chuck to our customer in Mexico as a replacement of his existing 4-jaw chuck. This chuck has A2-15 short-taper direct mount to lathe spindle. Its bore diameter is 150mm, allowing the jaw travelling to pretty large to clamp small diameter. On request, the jaws on this independent chuck can be made into bolt-on 2-piece type. Also we can make this size of chuck into self-centering type having the jaws number as you desire. We accept customizing order for even only one chuck.
