Abstract: The invention provides an excavation bit, which is constructed from either a single or double carrier. If two carriers are present the carriers are contra-rotating. By the off setting of the axes of rotation of single or dual carriers from a longitudinal axis of the bit, and by driving to carriers to rotate, a ground engaging thrust is produced, as well as the rotation of the excavation bit in the ground as a consequence of the rotation of the carriers, and not vice versa as is the case with prior art. By the invention, there can result sufficient thrust on the bit, by the rotation of the carriers, so that the need to apply thrust down the bore via the drill rod is reduced or eliminated. As a result of the invention the number and or size of the ground engaging tools are not a function of the bore diameter to be drilled. Thus as the excavation bit is scaled up for larger diameter bores more ground engaging tools and or an increase in their size is not required.
