Wide application: suited for calibrating workshop machines like table saws and drills; an essential tool for every woodworker. Wear resistant material: Made from stainless steel that has undergone temperature quenching; offers exceptional wear resistance and durability. Accurate and sensitive: Delivers clear readings to enhance your calibration process. Adjustable length: Innovative sliding head design; measuring length adjustable from 130 to 220 mm (12 to 8.66 inches), providing flexibility for various applications. Use scenario 1: Calibrate a table saw by aligning the blade with the fence and checking for parallelism to ensure precise crosscuts. Use scenario 2: Set and verify drill press depth stops and travel limits to achieve consistent hole depth. Use scenario 3: Use as a reference for stop positions on other tools such as bandsaws or routers that require exact measuring lengths.
