Abstract

Pneumatic hammer intended to receive a drilling bit and consisting of a tubular rod at the end of which a sliding bit whose stroke is limited by a key can be applied, including the inside of the rod, also a compressed air distribution mechanism that commands the movement of a hammer acting on the end of the bit, characterized by the fact that, at the end that receives the bit, the inner surface of the tubular rod is cylindrical in shape with a regular polygonal section with at least six sides, and then cylindrical in shape with a circular section with a diameter less than the circle inscribed in the polygonal section, the two parts having a polygonal and circular section being joined by a conical surface of revolution, the axes of all the lower surfaces being confused with the axis of the hammer .
