Abstract: The present invention relates to drilling equipment and more particularly to turbodrills, having a casing with multistage turbine stators fixed therein and a shaft mounted therein. The shaft is formed by a plurality of smaller shafts connected to each other in series, and including a spindle assembly the shaft of which drives a bit into rotation and is mounted in a ball bearing means. According to the invention, the shafts provided with rotors are mounted in ball bearing means and are connected to each other and the shaft of the spindle assembly with the possibility of relative displacement of said shafts. The present turbodrill is used for drilling deep and directional wells. The turbodrill provides a low dynamic load on the bit, elimination of axial and transverse vibrations of the turbodrill shaft, and a long bit life between overhauls.
