Precision 8 inch self-centering chuck with 3 inside jaws and 3 outside jaws.  Use to hold parts for machining, welding, laser marking, and many other applications.  You can place this chuck onto a desk or worktable to hold parts or tools, acting like a steady third hand.  These jaws are self-centering and move in and out synchronously and accurately, meaning you only need to tighten one to move all 3 jaws.  If you need independent jaw movement, then order our Chuck8-4Jaw-I.
