ABSTRACT:
A punching tool for producing weep holes in a sill can utilized for window installations is disclosed. The tool has pivotally mounted jaws operable by a handle assembly with a punch formed flush with an end of a first jaw and a die opening provided in an end of a opposed second jaw. The pivotal connection of the jaws maintains the punch and die opening in arcuate alignment as the jaws are pivoted. A throat of the tool receives the upstanding leg of the sill can with the formed punch fitting flush against the bottom of the sill can and thus the tool will produce a weep hole in the upstanding leg flush with the interior bottom of the sill can as the jaws are pivoted toward each other. A large surface area surrounding the die opening in the second jaw prevents marring of the sill can exterior surface.
