Improved borehole, essentially characterized in that it consists of a hollow body, of a substantially inverted frustoconical structure, has a bottom, whose surface is symmetrically emphasized in oblique planes, forming a broken and symmetrical section, with a stepped shoulder superiorly and concentrically, that in two diametrically opposed points, it presents two supports of the transport handles and that they are constituted by prismatic parts in their upper part and truncated-pyramidal in the lower one, whose truncated vertex is entangled with the inner constructive line of the referred rim.
