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.
