Starrett's 12" Combination Set includes both center and protractor heads; the square comes with a satin chrome blade. The blade is graduated in 64ths & 32nds on one side, 16ths & 8ths on the other. The blade can be reversed to read whichever scale is most convenient for a given job. The 12" Combination Square offers dependability for layout and checking cutoff accuracy. Heads are forged, hardened steel with a smooth enamel finish. This set includes the accessories to convert the 12" square into a center finder for round or square stock, or into a large precise 180° satin chrome reversible protractor for determining or laying out uncommon angles.
