ABSTRACT:
A fixed blade assembly rigidly mounted adjacent the oppositely disposed ends of a 7 feet 4 inches of drill pipe with a spinner assembly mounted for rotation and linear movement therebetween. The spinner assembly, randomly rotating and assisting the fixed blade assemblies to center a drill stem in a vertical hole, is stopped by intersecting the side of a drill hole when the drill string starts to deviate from the vertical, and acts as a prize against the side of the drill hole to pry the lower end of the drill string back to vertical and return to random rotation. A jaw-lock assembly is provided between the spinner assembly and the lower fixed blade assembly for wash-over operation should the drill, tool or drill stem stick.
