Abstract
An apparatus and method for first drilling a hole in a workpiece by utilizing a locating jig, and then inspecting the hole to insure it is drilled to the proper diameter. There is an inspection device having an inspection probe that is pivotally mounted about a universal mounting device so that the lower inspection end of the probe is able to deflect laterally to fit in the drilled hole so as to be centered therein. This arrangement compensates for any misalignment in the positioning of the inspection apparatus relative to the earlier alignment of the drilling apparatus.
