What is a bevel protractor?
|A (universal) bevel protractor is used to measure angles of objects. You might see it used with various objects, including jigs, and when producing engineering/machine drawings.
|Unlike a regular protractor, a bevel protractor is adjusted to fit the angle.
|The base is placed on the bottom side of the angle, whilst the blade is moved to match the opposing side.
|In addition to a degree scale, many bevel protractors will have a vernier scale on them as well, normally found underneath the degree scale.
|Like combination square sets, some bevel protractors may be ground, made from steels such as stainless steel, and also have a satin chrome finish to help the user read the scales more easily.
|Likewise, they may come in boxes/cases in which they can be kept when not being used.
|Variants of the bevel protractor do exist; some use a dial to display the reading and are called “dial (or indicator) bevel protractors”.
|Some have a somewhat different design and are known by names including “universal precision protractor” and “precision universal vernier protractor”. These may be more technical in nature.
|Quite simply, designs may vary from manufacturer to manufacturer. Consulting your instructions will give guidance on how to use your product correctly.
