A miter gauge is a tool used in woodworking and metalworking to make precise angled cuts. It typically consists of a flat base that slides along the table of a saw, with an adjustable arm that can be set to various angles, usually between 0 and 45 degrees. This allows users to create accurate miter joints, which are essential for projects like picture frames and furniture. Miter gauges are commonly used with table saws, band saws, and router tables. They help ensure that cuts are consistent and repeatable, improving the quality of the finished product. Proper use of a miter gauge can enhance safety and efficiency in the workshop.
