The Groz Craftsmen’s Spring Internal and External Calipers and Divider Set is useful for marking on metal, comparing internal/external measurements or transferring measurements from master templates, which are especially useful for craftsmen. Made from a high-grade steel, these calipers’ legs are machined to a smooth taper and coated with a black powder finish. Securing these legs are finely machined and polished nut run smoothly for a precise dimension and measurement. The fulcrum stud has a large bearing surface preventing side deflection of legs. This divider is overall precision made to rigid standards, valuable to toolmakers and mechanics. The divider points are hardened 50-55 HRC for increased wear resistance.

This set comes with a Spring Internal Caliper, a Spring External Caliper, and a Spring Divider, all 8” in leg length.
