Driving head for pneumatic pile drivers

A driving head which can be used for pneumatic pile drivers, and which can serve as an attachment head for rods and pipes which are to be driven in by a pile driver;

• said driving head comprising an essentially circular front end, and a surface which essentially expands conically from said front end and which is provided with a plurality of longitudinal grooves that start from said front end, that have a V-shaped opening cross section, and that are uniformly distributed over the periphery of said surface;
• said surface of said driving head being formed of a plurality of conical sections which are offset from one another in the manner of steps as a consequence of jumps in the diameter of said surface, with end faces being formed thereby between respective conical sections, said end faces extending in a circular manner around said surface, being interrupted only by said longitudinal grooves;
• said end faces furthermore being disposed at an angle in a range of from 45.degree.-90.degree. relative to the longitudinal center line of said driving head.
