Abstract
Improved drill, characterized in that the head is rotatably coupled to the end of a horizontal axis which is the one that engages with the column on the opposite side, for which purpose it has mounted on its upper end a piece "T" embrace it is rotatably coupled on the column and which receives transversely to the horizontal axis carrying the head, but with a rack ratio of this engaging with a crankable drive sprocket included in the "T" part, so that with it displacement will occur of the head-holder shaft in one direction or in another to position said head by adjusting its distance with respect to the column, to which is added the possibility of angular positioning in rotation of the "T" piece on said column, (Machine-translation by Google Translate, not legally binding)
