A hinge drilling jig for use in the '32 mm' or face-frameless system of cabinet construction for locating and drilling the hinge cup and the hinge cup mounting screw holes to be drilled in a cabinet door. A flat bottom drill bit is slideably retained in a jig body for drilling the hinge cup hole, and two thumbscrews locate the jig on the face of the cabinet door relative to its vertical edge. A collar retains the drill bit in the body and a shoulder on the drill bit and annular rings cut on the shank of the drill bit allow measurement of the depth of the hinge cup hole prior to being drilled by the drill bit. A plurality of countersinks on the body locate the position of the hinge mounting screw holes on the face of the cabinet door in predetermined positions. The jig is held in position on the door by a handle or a clamping arm having a clamping screw and a gauge assembly locates the jig on the face of the cabinet door relative to the second edge.
