ABSTRACT:
A device for making or regenerating a water well, said well comprising a casing installed inside a borehole in the ground. The device comprises a operating head with angularly equispaced radial seats in which respective punch tools for forming holes, windows or shaped cuts in the wall of the casing are slidingly housable. The head is operated from the mouth of the well to a position at a preestablished depth inside the casing so that the radial seats are orthogonal to the wall of the casing. Operating means are integral with the head to axially move the tools inside the respective radial seats to and from the wall of the casing.
