A mortiser device and method for applying a mortise or offset in the edge of a hollow metal door where a dead bolt or other latch is to be installed. The method and device comprises a die block adapted to be positioned inside of the door edge at a point adjacent where a mortise is to be formed in the door edge, a cavity in the die block, a mortising block operatively connected to the die block by a pressure application device, whereby the mortising block is disposed on the outer side of the door edge adjacent the die block and a portion of the door edge extends between the die block and the mortising block. The pressure application device extends between the die block and the mortising block through the aperture in the door edge, and the pressure application device is adapted to press the mortising block and the portion of the door edge extending between the die block and the mortising block into the cavity in the die block to form an offset in the door edge.
