A nail set device is set forth wherein a housing comprises a central cylindrical cavity extending interiorly of the housing from one end to receive a punch therewithin. The housing is formed with a forward planar wall with an axial bore extending from the planar wall through the other end of the housing axially aligned with the cylindrical cavity. The punch includes a reduced section to receive an abutment screw to control axial punch travel within the housing. A forwardly mounted return spring between the conical forward wall and a central enlarged diameter portion of the punch maintains the punch in a retracted orientation relative to the housing. A forward resilient bumper is mounted overlying the forward reduced circular section of the housing to minimize damage to an associated work surfaces.
