Bench-mounted, the Gunsmithing Vise swivels 360 degrees on its base. The upper portion can also be lifted off the base, turned on its side and reattached, placing the jaws in a vertical position. Great for metal work, soldering, filing, drilling, holding stocks for sanding and inletting. The innovative design locks the rotation at the point where the jaw is clamped. Simply loosen the jaws, move the work to its position and tighten the jaws. Also includes a flat ground anvil surface on top for peening and punching. Heavy cast iron construction for easy operation and long life. 3-1/2" jaws open to 4-3/4", weighs 18 lbs.
