A bench vise is a tool used to hold objects securely in place while you work on them. It typically consists of two jaws, one fixed and one movable, that can be tightened together using a screw mechanism. This makes it easier to saw, drill, or shape materials like wood or metal without needing an extra hand. These vises are commonly found in workshops and garages, making them essential for DIY enthusiasts and professionals alike. They come in various sizes and styles, including mechanical vises and rotating vises, to suit different tasks and preferences. A good bench vise can greatly enhance your efficiency and precision in any project.
