A miter gauge is an accessory used with band saws, table saws, or other cutting tools to guide and position the workpiece during miter cutting. Miter gauges typically feature an adjustable protractor head, a fence, and a guide bar that slides in a slot on the cutting tool’s table. The miter gauge allows the user to set and maintain a precise cutting angle, ensuring accurate, repeatable miter cuts. Some miter gauges also include stops or extensions for added convenience and accuracy.
