Beschreibung
Zusammenfassung:	Improvements in the devices for drilling different hardness masses, such as plaster and/or concrete, composed of a drilling rod, which has a stop projection, as well as by a drilling knife that is attached to the drilling rod and having lateral cutting edges intended for the realization of a depulladura inside the drilling hole, characterized in that the stop projection, located in the central part, seen in the longitudinal direction, can be supported, in order to constitute a swinging support, inside a mold located below the stop projection disposed in a stop square that has been placed above the drilling rod located in the central part of the plane, forming its line of symmetry, and resting on the surface of wall.
