ABSTRACT:
A marking tool assembly includes a plurality of marking punches for stamping alpha
umeric indicia into a workpiece. The punches are adapted to be indexed selectively to an active punching position beneath a striker which causes one of the punches to stamp the workpiece during the downstroke of the tool, the remaining punches resting idly on the workpiece. A stripper ring holds the striker rotationally stationary and also prevents rotation of a retaining ring for permitting up and down sliding of the punches in a holder and for guiding the punches to the active punching position.
