vise

A vise is a mechanical clamp used to hold an object firmly in place during work such as sawing, filing, drilling, welding, or gluing. It typically consists of two jaws, one fixed and one movable, that are brought together by turning a screw or lever. Vises are essential in woodworking, metalworking, and various crafts, providing stability and allowing precise manipulation of the workpiece. In American English the term is commonly spelled “vise,” while “vice” is used in British English and some other varieties.

Common types include the bench vise, which mounts to a workbench and often features a swivel base for angle adjustment; the machinist vise, which provides higher precision and is used on machine tools; and specialized vises such as pipe vises for holding round objects. Some benches also include a tail vise or face vise as part of the bench’s integrated clamping system. Vises may have replaceable jaws, adjustable anvils, and, in some models, quick-release or cam-action mechanisms for faster operation.

Key components are the fixed jaw, the movable jaw, the screw mechanism or quick-release lever, the handle, and the base or mounting interface. Jaws may be lined with hardened steel or replaceable soft jaws to prevent damage to delicate workpieces. Materials are typically cast iron or steel for strength and rigidity.

Usage tips include aligning the workpiece parallel to the jaws, clamping with appropriate force to avoid deformation, and protecting delicate surfaces with soft jaws or inserts. Regular maintenance such as cleaning debris and lubricating the screw helps maintain smooth operation and longevity.
