Device applicable to machines used to open holes in rocks, characterized by the application of a constant and adjustable pressure of the tool on the rock, using a piston and a cylinder, both pushed by a fluid under adjustable pressure, and because a motor started at each end of the stroke by the piston or by the cylinder, by means of an automatically operating valve, causes a forward movement of the cylinder or of the piston which allows re-sealing and which contains the pressure on the tool, whatever the length of the guide column that the machine supports.
