The iGaging® Combination Square Set includes a 12" combination square, a 6" combination square, and a foam-lined protective hard case. This pair of popular square sizes is perfect for woodworkers on the go—just grab the case, toss it in your tool bag or box (or even the back of the car), and be ready to measure and mark with precision. Both squares feature hardened satin chrome blades for scratch resistance, and precision lapping on all measuring surfaces for smooth operation. The cast iron heads have vial levels and metal scribes. Graduations are marked in 1/8", 1/16", 1/32" and 1/64" increments for easy measuring, no matter how precise your requirements are.
