How to Use Metalworking Protractors with the Starrett C183 Steel Protractor

In setup for machining, layout and inspection, determining an angle is among the most common activities. Our bevel vernier protractors provide the highest level of precision. Also very precise is a protractor head and blade set from our combination square family. We offer a variety of tools with a sharply graduated 180 degree scales intersected by a movable blade, a bevel protractor, protractor/depth gages and special drill point gage.

When drawing an angle do use the inside or outside of the metal bar?
