Hardware installation tool

A device for drilling a series of holes in the face of a workpiece relative to a first edge and a second edge perpendicular to the first edge, comprising a generally rectangular base, a plurality of aligned drills mounted vertically movably on the base, a plurality of spring biased stop pins retractably mounted on the underside of the base, the row formed by the stop pins being parallel to the row formed by the aligned drills such that the drills may be located a fixed distance from the second edge by the stop pins, first adjustable stop means located on a first edge of the base adjacent and generally parallel to the stop pins for adjustably setting the distance of the drills from the second edge of the workpiece when the spring biased stop pins are retracted into the underside of the base, second adjustable stop means located on a second edge of the base, the second edge of the base being perpendicular to the first edge, the second adjustable stop means being selectively engaged or disengaged with the first edge of the workpiece, and at least one index pin on the base for insertion into a previously drilled hole when drilling new holes in line with previously drilled holes.
