A practical angle finder for accurate measurement and angle transfer. Designed for mechanics, carpenters, and students, it helps transfer angles and set bevel angles on cutting tools such as saws. Key benefits Accurate measurements for transferring angles and setting bevels on cutting tools such as saws. Versatile 0 to 180 degree semicircle scale with clear, readable markings for all angles; adjustable forward and backward for flexible use. Stable, slippage readings thanks to a knurled wing nut that locks the metal arm in place. Durable construction using quality stainless steel for long term reliability. What it offers Protractor angle finder with a smart semicircle scale that covers 0 to 180 degrees, enabling precise angle measurement and easy readability. Attaches securely to workpieces or tools and can be adjusted in both directions to suit the measurement task. Metal arm locks with a knurled wing nut to maintain position and prevent movement during measurement. Specifications and build Material: stainless steel for durability and corrosion resistance. Scale: semicircle 0 to 180 degrees for measuring all common angles. Function: transfers angles and helps set bevel angles on cutting tools such as saws. Operation: attaches to objects, adjustable forwards and backwards, lockable with a knurled wing nut. Use scenarios Scenario 1: Transferring an angle from a drawing to a workpiece by attaching the finder, aligning to the angle, and marking for cutting or drilling. Scenario 2: Setting the bevel angle on a saw or other cutting tool by aligning to the desired angle, then locking the arm to maintain the setting during operation. Scenario 3: Verifying angles on metal brackets, joints, or other components during DIY projects, repairs, or hobby machining to ensure accuracy and fit. This angle finder delivers precise, reliable measurements with durable stainless steel construction, making it suitable for professional use in workshops and for educational purposes in classrooms.
