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.
Claims40
An apparatus for boring holes, comprising:
- a horizontal directional drilling (HDD) bit comprising a bit body of a metal material, the bit body including a mounting region defining at least one mounting aperture, and an engaging region extending forwardly from the mounting region, the engaging region being fixed relative to the mounting region, the horizontal directional drilling (HDD) bit including a cutting face along the engaging region, and wherein at least one cutter tooth of the metal material is integrally formed into the engaging region providing a toothed profile to the cutting face.
An apparatus for boring holes, comprising:
- a horizontal directional drilling (HDD) bit comprising a bit body of a metal material, the bit body including a mounting region defining at least one mounting aperture, and an engaging region extending forwardly from the mounting region, the engaging region being fixed relative to the mounting region, the horizontal directional drilling (HDD) bit including a cutting face along the engaging region, wherein the bit body comprises opposed first and second side faces and a peripheral border edge extending transversely between the opposed first and second side faces;
- a hard face coating comprising a hard face material harder than the metal material of the bit body to provide for increase wear resistance;
- and
- wherein the peripheral border edge is joined to at least one of the first and second side faces through at least one broken corner edge defined in the bit body, the hard face coating covering the at least one broken corner edge.
