A support with pneumatic advance for hammer drills essentially constituted by an apparatus composed of a cylindrical body through which a piston connected to a piston rod can slide when it is penetrated by governing its entrance by means of a key placed within reach of the hand of the air operator to the pressure in the cavity of the cylindrical body closed by the plunger so that there is a displacement of one relative to the other that varies the length of the device to one of the two elements of which is preferably fixed at the end the hammer that has of being held hammer that is by the action of the compressed air displaced to the place of action and there pushed against what it has to drill resulting in not only a relief of the effort of the operator who governs the hammer but a progressive advance of the latter in the appropriate direction to the perfect performance of it.
