Woodworking vises

For woodworking, the jaws are made of wood, plastic or from metal, in the latter case they are usually faced with wood to avoid marring the work piece. The top edges of the jaws are typically brought flush with the bench top by the extension of the wooden face above the top of the iron moveable jaw. This jaw may include a dog hole to hold a bench dog. In modern metal woodworkers' vises, a split nut is almost universally used. The nut in which the screw turns is in two parts so that, by means of a lever, it can be removed from the screw and the moveable jaw can be quickly slid into a suitable position at which point the nut is again closed onto the screw so that the vise may be closed firmly onto the work.

Metalworkers' vises.

For metalworking, the jaws are made of metal which may be hardened steel with a coarse gripping finish. Removable soft jaws are usually kept for use where appropriate, to protect the work from damage.

Metalworking bench vises, known as engineers' or fitters' vises, are bolted onto the top surface of the bench with the face of the fixed jaws just forward of the front edge of the bench. The bench height should be such that the top of the vise jaws is at or just below the elbow height of the user when standing upright. Were several people use the one vise, this is a counsel of perfection but is still a good guide.

The nut in which the screw turns may be split so that, by means of a lever, it can be removed from the screw and the screw and moveable jaw quickly slid into a suitable position at which point the nut is again closed onto the screw. Many fitters prefer to use the greater precision available from a plain screw vise. The vise may include other features such as a small anvil on the back of its body but it is in general, better to separate the functions of the various tools.

Vise screws are usually either of an Acme thread form or a buttress thread. Those with a quick-release nut use a buttress thread.

The word 'vise' comes ultimately, from the Latin word vitis (vine), referring to the helical tendrils of the vine. The more direct source is the French vis, screw.
