The blade has one end of 45 degrees, and the other has an angle of 30 degrees so that 45 degrees & 30 degrees can be directly measured using these edges. When the blades are parallel to the stock, the zero of the Vernier scale corresponds to the zero of the main scales or the dial scale. These blades are either 150 mm or 300 mm, depending on the bevel’s protractor. It is divided into four divisions of 360 degrees, every 90 degrees. At this graduation, every tenth degree is counted. It has a graduated level of angle from a value of 0 degrees to 360 degrees. This dial scale is the core of the bevel protractor.

The main scale or dial scale is marked on this dial. This is the basis of the bevel protractor on which the other parts are present. This angle prevents the swivel plate from rotating in relation to the locking screw dial or dial scale. 229910052782 aluminium Inorganic materials 0.This angle locking screw is used to locks the bevel protractor at a fixed angle so that the locking angle can be measured without any disturbances.229910045601 alloy Inorganic materials 0.000 description 1.229910000831 Steel Inorganic materials 0.000 description 1.
