This telescoping gauge set provides a measurement range of 0 to 6" (0 to 15.2 cm) for determining the internal diameter of holes, slots, and bores. The spring-loaded plungers expand within the workpiece and lock into position, allowing for the transfer of internal dimensions to a micrometer or caliper.
