ABSTRACT:
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.
