Digital & Mechanical Protractors
Available2 products
Digital and mechanical protractors measure angles, inches, and bevels. Mechanical versions can be read manually with a vernier scale. Digital versions show measurements on a LCD display. Miter protractors are mechanical with two arms or wings that extend from a central hub that is graduated with angles and fractions of angles. A central dial points to the reading as the two arms are aligned with the surfaces being measured. Miter protractors can also transfer angle readings directly to a miter saw. Bevel protractors are used to check angles on machines or parts with a high degree of accuracy. They have a beam or base that is stationary and an adjustable arm or blade that rotates 360° with a locking mechanism that keeps measurements in place. Digital protractors and angle finders show readings on a LCD display. Protractors are commonly used in carpentry, molding, metalworking, plumbing, and general MRO applications.

Manual-Reading Protractors
These manual-reading protractors resemble basic school-style protractors. They have a square or round head with a 180° arc marked on the body. Select models include a blade that may be etched with graduations, while others may require a rule or straight edge to read accurately. These protractors are commonly used for woodworking and metalworking applications.

Manual-Reading Miter Protractors
Manual-reading miter protractors are used to find angles on corners. These protractors have two flat arms that extend from a central pivot assembly where angle scales are marked. These arms rotate to come flush with two adjoining surfaces that need to be measured. They typically have a single-cut scale and miter-cut scale, so when an angle is needed for a miter cut, there is no need to do extra math. They are commonly used in carpentry, plumbing, and general building trade applications.
