WORKPIECE PERFORATING MACHINE ABSTRACT OF THE DISCLOSURE A machine for perforating workpieces, particular- ly corrugated plastic drain pipe or tile, to produce holes using drills is described. Multiple drills are radially mounted on a guide wheel so that the individual drills are sequentially extendable from the periphery of the guide wheel into the workpiece as the guide wheel rotates against a surface of the workpiece. A motor rotates a drive disc which as the guide wheel rotates sequentially contacts a cylindrical bushing on each drill to extend and rotate the drill into the work surface to create a perforation or hole and the drill is then extracted from the perforation by the rotation of the guide wheel.
