A bench vise is a mechanical device used to securely hold an object in place while work is being done on it. It typically consists of two parallel jaws, one fixed and one movable, which can be adjusted using a screw mechanism. Bench vises are commonly found in workshops and garages, making them essential tools for tasks like woodworking, metalworking, and general repairs. These vises come in various sizes and designs, including those specifically made for woodworking or metalworking. A well-made bench vise can provide stability and precision, allowing users to work safely and efficiently on projects involving materials like wood, metal, or plastic.
