Protractor angle finder for carpenters, mechanics, and students. Easily transfer angles and obtain precise measurement values for bevel angle settings, suitable for any project or assignment. Smart angle detection: Features a 0 to 180 degree semicircle scale for accurate measurement of all angles. It can be fixed to an object in both backward and forward directions, enabling flexible angle inspection and assessment. Angle finder advantage: Measure any angle with accuracy. Lock the metal arm in place with a knurled wing nut to ensure stability and prevent slippage or movement, delivering reliable readings. Better measurement: Made of quality stainless steel, helping DIY enthusiasts achieve improved measurement results. Use scenarios: Woodworking: accurately set bevel cuts and transfer angles from templates to workpieces for precise joints. Mechanical maintenance and assembly: align components and verify angle orientation during installation. Education and DIY projects: verify angles for geometry assignments or home improvement tasks.
