[Digital Protractor Angle Finder] The new Woodworkers Edge Rule simplifies your life by wrapping around the edge of your stock and giving you an accurate scale on both sides. [Unparalleled Accuracy] Our latest precision ruler provides high accuracy for panel layout work. Set the desired angle and press the straight line. The tool adjusts between 0° and 70°, locking firmly every 5° to provide accurate reference angles and lengths. [Woodworkers Edge Rule] The T-Square features precisely machined indexing holes and a spring-loaded, tight-tolerance indexing pin that securely engages with the holes. The pin snaps into place, ensuring precise and reliable alignment. Both edges of the blade are laser engraved with an inch scale in 1/32 inch increments. Graduations are held to a tolerance of ±0.004 inch total accumulated error over the length of the blade. The thin, satin-finish stainless-steel blade is easy to read and minimizes measurement errors. [Perfect Woodworking Layout Tools] Even when not working with angles, this layout tool is ideal for nearly every project. The blade includes a "saw-tooth" design with scribing notches similar to those found in Stainless Steel Precision Woodworking Squares. Place your pencil in the notch and slide along the edge of your stock for perfectly parallel lines.
