Home and Crafts in 1 Digital Protractor 300mm Digital Angle Measuring Scale with LCD Display and Lock Function for Woodworking [2 in 1]Combination of ruler and protractor for easy measurement. Used simultaneously as a digital protractor and protractor to measure all workshop angles. The digital angle gauge has laser-etched metric and imperial sizes on the edge of the ruler, as well as an accurate digital display, and can measure both angle and length, which is very suitable for carpentry, construction or drawing. [High Accuracy]The accuracy of this digital angle ruler is ±0.5 degrees. Measuring range: 0-360° or 0.00°-999.9°. Folded length: 11 inches or 300 mm. Total length 600 mm. It is a great choice for most projects and daily use, for DIY family projects, woodworking, decorating, and machining. [Lightweight and Durable, LCD Display] Digital glass bevel angle finder made of thickened nylon, wide, high-strength nylon fiberglass material, good rigidity, wear resistance, no deformation. When measuring an angle, the protractor has a large, easy-to-read LCD display, and you no longer need to look and guess the angle and length. [360-Degree Inversion] The digital protractor tool has a reversal function. Place the angle finder gauge where you need to measure the next cut, lock it in place with a knurled locknut, mark it, and then use a miter saw to cut. The display has a hold function that can freeze the movement to ensure accuracy. You can save a lot of time and energy.
