A metalworking vise is a tool used to securely hold metal pieces in place while they are being worked on. It typically features two parallel jaws that can be adjusted to grip various sizes of materials. Metalworking vises are commonly made from durable materials like cast iron or steel, ensuring they can withstand heavy use in workshops. These vises are often mounted on workbenches or tables, providing stability during tasks such as cutting, drilling, or welding. Some models include additional features like swivel bases or quick-release mechanisms, enhancing their versatility and ease of use for metalworkers and machinists.
