Description

The Starrett 12ME-300 Bevel Protractor is a non-reversible bevel protractor that has revolving turrets with direct-reading double graduations, 0 to 180° in opposite directions, for accurate reading of angles above or below the blade. The protractor has a 12″ (300 mm) tempered steel blade, with 1/2 mm and 1/32″ graduations on one side, and 1 mm and 1/64″ graduations on the reverse side. The protractor head is cast iron with a black wrinkle finish. A sprit level determines if the reference surface is level.

Protractors are tools that measure specific angles, which allow users to create and replicate desired angles. The tools include a stationary base and movable rule, usually connected by a scale that may be digital or manual. They are useful in a wide range of applications, such as measuring crown molding and installing baseboards. A protractor can be included as part of a combination set, along with a center and a square. A center accurately locates the center of a circle or cylindrical rod. A square is used to scribe right angles and parallel lines, calibrate miter and table saws, or as a miter, height gauge, or depth gauge.

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
