Abstract
Improved drilling unit; It consists of a drill stem, a blade, which is attached to the stem and is equipped with lateral cutting edges to perform a polishing inside a drilling drill, the drilling unit also carrying a stop rosette, movable and fixed on the Drilling and supportable stem, in order to constitute an oscillating bearing, in a half-shank of the stop plate which in turn is pierced over the drilling stem, characterized in that the drilling stem has, in several notches, made in the same at certain distances from each other, in which a latch can fit, which is guided by the wall of the stop rosette and is pressed by the force of a spring against the drill stem.
