Abstract
A wear gauge confirms the acceptability of an outside diameter of a down hole drilling tool for down hole service. An embodiment of the wear gauge has two arcuate members pivotally connected in overlapping attachment, where each arcuate member has opposing ends and an arc length is defined between the two ends. Each of the opposing ends has an aperture penetrating through the width of the arcuate member. The free ends may be pivoted together into an overlapping configuration into a closed position. When in the closed position, the two arcuate members define a circle. The diameter of the circle is certified to be a specific value within a designated tolerance.
