The drywall die-cutting tool is comprised of a female plate having a center opening outlining a given size and shape with four corner holes to receive the legs of the extracting mechanism, and a male plate, being the cut-out of the female plate. The male plate has attached to the back face a convenient number of spring prongs to provide temporary fixation to an outlet box supported an a wall stud, said male plate also has, perpendicular at the center of the front face, a rectangular sharp pointy biade able to penetrate through a drywall board or any covering material when placed and pressed against it. The extracting mechanism, already engaged to the corner holes of the female plate, and having a sliding shaft which houses and engages the blade, has an arm lever that when pressed pulls the sliding shaft engaged to the blade, exerting a pressure between the interior male plate, the center drywall board, and the exterior femal plate, thus forcing the male plate through the female plate producing in this manner the desired hole in the drywall board. Once this is executed, the whole tool can be pulled out and disengaged for the next operation.

A die-cutting tool for locating and cutting openings of a given size and shape in installed drywall boards, to permit access to electrical outlet boxes, said die-cutting tool comprising: (a) an interior male plate having a lengthwise and widthwise perimeter of the same shape as the front face of the given outlet box, said plate having front and back flat surfaces, and, a plurality of spring prongs on said back surface that provide a temporary means of support to the outlet box for said plate by penetrating through the existing holes of the outlet box or friction against the inner walls of the outlet box if no holes are present; a rectangular knife blade attached perpendicularly at the center of the front surface of the plate, said blade terminating in a rectangular pyramidal sharp point having a hole across the width side to provide a connection with an extracting mechanism, (b) an exterior female plate having front and back flat surfaces with an interior opening of a slightly larger perimeter but identical shape as the male plate, with a plurality of fitting holes therein with which to secure the extracting mechanism; (c) said extracting mechanism having as a base, a table with a plurality of legs corresponding to said fitting holes on said female plate, and further including a handle with an interior rectangular guide, housing a rectangular sliding ratchet shaft, said shaft capable of moving back and forth and defining means for attachment to said knife blade; said handle having attached thereto a shaft-retaining pawl and an arm lever with a second pulling pawl co-operating with the ratchet shaft so that when the arm lever is pressed against the handle, a resulting backwards displacement is produced, pulling the male plate against the drywall board and the female plate, thus causing the said male plate to pass through the inside of the female plate, cutting out a piece of the drywall board in the same shape as the male plate and producing said opening in the panel in front of the outlet box.
