Beimgraben, H W

An apparatus is provided for effecting a change in direction of a rotary drill bit relative to a work string. Two tubular components incorporated into the work string have a rotationally adjustable connection for angularly displacing the drill bit axis relative to the tubing string. One embodiment has the connection between a housing for the shaft of the drill bit and the housing for the motor which drives the shaft. The connection comprises a pair of cylindrically disposed interengagable surfaces formed on the adjacent ends of the motor shaft housing and the drill bit housing, which have axes that are slightly angularly displaced from the housing axes.
