Four Piece Combination Measuring Set

12” Rule, Combination Square, Protractor, & Center Finder Set with Storage box

The combination square is one of the truly indispensable shop tools, used not only for checking angles for accuracy, but for marking, gauging, and transferring measurements. Our four-piece combination square set does all that and more, with great accuracy you can fully rely on for excellent results.

The glare free precision fully hardened steel blade is satin chrome finished, is graduated in 8th, 16th, 32nd, and 64th inches, and has an easily adjustable locking mechanism. The 12” blade is removable and works great on its own as a highly accurate standalone rule.

The cast iron square/miter head measures 45° and 90° angles and features a built-in bubble level in the handle, and a hardened scribe tool. Add to this a protractor graduated from 0°–180° in both directions to accurately set or measure any angle, plus a 45° center finder that will find dead center of square or round stock. Comes with a convenient plastic case for organization, storage, and protection of the pieces.
