Abstract:

A versatile portable workholder can be used as a vise, a V-block and a drill jig for holding different sized and shaped workpieces. The workholder includes a vise comprising two jaw pieces actuated by a screw member. A clamp can be clamped in the vise and includes a second screw member for clamping a workpiece between the clamp and the vise. A stop member is connectible to the vise for positioning or locating a workpiece relative thereto. The second screw member has a bore and serves as a drill bushing.
