Essential tool for accurate readings This protractor is an essential tool for mechanics, technicians, and students. It helps transfer angles and set chamfer angles on cutting tools such as saws, enabling precise setup and reliable results. Accurate angle rating Measures all angles from 0 to 180 degrees on a semicircular scale for accuracy and easy readability. It can also be attached to a workpiece and moved forward or back for angle measurement, improving versatility during measuring tasks. Precise angle measurement Features a metal arm that locks with a knurled wing nut, so you can determine your angle without slipping or moving. This locking mechanism supports repeatable marks and consistent cuts or joins. Better measurement Constructed from stainless steel, providing durability and stable measurements for DIY projects and repeated use. Common applications Woodworking and carpentry: set bevels and chamfer angles on saws or other cutting tools; transfer angles from drawings to workpieces with confidence. Metal fabrication and machining: align and measure angles on plates, brackets, and joints; transfer precise angles to parts before cutting or welding. Education and DIY projects: practice angle measurement, verify angles on project components, and support classroom or home learning with reliable tools.
