Abstract: A hard facing is preferably accomplished with laser clad beads applied to horizontal directional drilling (HDD) component(s). These components may be subject to recirculating fluid regions associated to stepped geometries along a drill string, including various drill string coupling members. For example, laser cladding can be applied to a step region of the sonar housing and starter rod. A method applies a hard face coating such as laser cladding or other suitable hard facing in areas of tight geometric tolerances.

Abstract: A new horizontal directional drilling (HDD) bit comprising a bit body is provided with illustrated embodiments including a flat bit design and a cobble bit design. Cutter teeth may be cut (e.g. formed or machined) into the base steel material of the bit body. Additionally, a broken edge profile may be generated to avoid sharp corners for better receipt of hard facing material such as laser clad beads that may be applied in higher wear regions.
