Starrett 6" junior combination square set with square head and centering head and blade.
These squares are used by mechanics, toolmakers and patternmakers because of their compact, small size and light weight. Both blade and heads are smaller than on regular squares. Heads are drop forged, hardened steel and have smooth, black enamel finish.
Chris' Tips The combination square was invented by Leroy Starrett (yes, that Starrett) in 1877. It's one of those basic tools that should be in every machinist's (and woodworker's) tool box.The name combination square is truly appropriate for this tool, as it includes 7 basic components and can be used in hundreds of ways. In one package you get 90° and 45° squares, a protractor, a centering head, a precision scale, two levels, and a scriber.Here is some information on using a combination square from Starrett.We carry several Starrett 12" combination square sets. What's the difference? There are several features that affect the price. One is the protractor head. Squares with a reversible protractor head cost more. Another is the scale. Squares with satin chrome scales cost a little more.
