Abstract
A tapered reamer bit which achieves a reaming function at least in part by tension fracturing a geographic formation such that the resulting fragments of the formation are forced upward and/or backward and without relying on multiple rotatably positionable cylinders disposed on the reamer bit. Because of the tooth placement of the tapered reamer bit, a rotational force applied thereto results in a downward/forward force while reaming out a hole through a geographic formation.
