A miter jig is a tool used in woodworking to make precise angled cuts, typically for creating frames or joints. It holds the workpiece at a specific angle, allowing for accurate and repeatable cuts on a miter saw or table saw. This ensures that pieces fit together seamlessly, which is essential for projects like picture frames or cabinetry. Miter jigs can be simple or complex, depending on the design and intended use. Some jigs are adjustable, allowing for various angles, while others are fixed for specific cuts. Using a miter jig enhances efficiency and accuracy in woodworking tasks, making it a valuable addition to any woodshop.
