ABSTRACT:
A directional boring apparatus is disclosed where the apparatus is controlled through a method which includes deviating a drill head from a straight path into a desired direction angled away from the straight path. The deviation is achieved by applying an axial force to the drill head when a drill head cutting member is positioned within an arc of rotation through which the desired direction passes. The drill head is retracted when the cutting member is outside of the arc of rotation.
