A rotatable groove depth gauge is mounted on a support member of the apparatus adjacent a stop element which engages the support member to determine groove depth, and the gauge is displaceable relative to the stop element into and out of a gauging position in which the stop element can be set to control the groove depth in a given workpiece.
