Abstract
A device for punching cutouts through sheets of drywall or similar wall covering sheets that are typically installed on framing members to which utility boxes are mounted. A cutting assembly is removably mounted over the utility or electrical boxes and the cutting assembly has substantially the same projected contour of these boxes with a puncturing member that cuts through the drywall. A pulling assembly engages with the protruding end of the puncturing member and adapted to pull it, and the cutting assembly to which it is rigidly connected, thereby producing a cutout that substantially follows the contour of the utility box that needs to be exposed through the drywall.
