Abstract
A boring bit such as for horizontal directional drilling is provided which includes a hard faced layer that is preferably made by a laser cladding bead. The laser clad bead may be applied in some regions to a greater extent and in other regions to a lighter extent and with thicker coverage or longer regions of application in different regions of the boring bit. Additionally, circumferential segments of the hard faced layer bead may be applied to impart a spiral path on the outer periphery of the boring bit which may be overlapped upon more general hard faced layer application. Further, the hard faced layer may be applied in substantially complete coverage over carbide insert teeth that are embedded within the steel base of the boring bit body.
