A dynamic steering tool for use with a horizontal directional drilling machine. The tool comprises and inner member, an outer member, a steering member, a drill stem, and a drill bit. The drill stem extends from within a borehole to the surface while the outer member only extends the length of the inner member within the borehole. The outer member is powered via the use of a progressive cavity motor. In operation, the drill stem, inner member, and drill bit rotate in a clockwise position while the outer member rotates in a counterclockwise direction. Rotating the outer member opposite the inner member allows the outer member to remain stationary and cause the tool to steer while the inner member continues to rotate.
