ABSTRACT OF THE DISCLOSURE The hole punch apparatus according to the present invention uses dies respectively mountable on the near and far sides of a workpiece, a housing engageable with the near die, and a shaft supported within the housing, insertable through apertures formed in the near die and workpiece, and engageable with the far die. A worm wheel is threaded on the shaft, and a worm is engageable with the worm wheel. A drive is engageable with the worm, whereby, when the drive is actuated, the far die is drawn against the workpiece, compressing the workpiece between the near and far dies, and the near and far dies cooperate to punch a hole in the workpiece. This apparatus is compact, light, easy to use and inexpensive. It is particularly suited for electricians and others who frequently punch holes of fairly large diameter in sheet metal for the passage of cable and the like.
