A bench vise is an essential and integral tool used in metalworking, woodworking, and some other manufacturing applications. It is mounted on workbenches and its main function is to hold the workpiece safely and securely. To state in simple terms, a bench vise is a mechanical apparatus used to secure an object that is to be worked on. It features two parallel jaws as part of the design. The device is widely used in the mechanical and woodworking industries, among others. The primary purpose of a machinist’s vise is to grab hold of things and to hold them steady in its rough jaws, freeing up both your hands so that you can bend, shape, hammer, cut, drill, or perform any number of other operations.
