Abstract

Improved perforator, characterized in that it consists of a bit element, formed by a rod of polygonal section to which an electric or manual drill can be coupled, and a cylinder-conical body finished in a toothed tip, which carries in its conical part two recesses diametrically milled opposite, which together with the conical surface, define cutting edges with an angle appropriate to the material, this drill is wrapped by a tubular body, which carries a helical groove, in which slides a key interlock, inserted in a drill of the body of the drill; in such a way that when sliding said locking key through the helical groove, the bit solidaria with it will vary its relative position with respect to the envelope tube projecting its conical part more or less, which when drilling will make the diameter obtained to make butt with the tube is larger or smaller, depending on the position in the helical groove of the interlock key.
