This object is a woodworking miter gauge, a high-precision tool used to guide wood at specific angles across a table saw, router table, or band saw. It is constructed from a durable aluminum alloy and features a 450mm (17.72 in) miter bar designed to fit into standard 3/4" x 3/8" miter slots. The gauge allows for accurate cross-cutting with an adjustable angle range from 0 to 60 degrees, often featuring preset stops for common angles and an ergonomic handle for safe, controlled operation.
