ABSTRACT:
A rotary tool is rotationally coupled to but axially slidable along a shaft that is driven by a motor. This tool is biased axially in one direction by a compression spring on the shaft and in the opposite direction engages via a thrust bearing on a force-transmission member. A spindle threaded in the machine housing engages this force-transmission member via a ball centered on the axis so that when the spindle is screwed relative to the housing it can axially displace this force-transmission member against the force of the spring to position it.
