摘要： An assembly for housing a beacon comprising a number of tools for tracking and locating a drill bit. The assembly is for use as part of a drill string for horizontal directional drilling applications. The housing allows the beacon to be loaded at an end, and provides a side window at an opposite end for viewing the orientation of the beacon within the housing. The housing comprises a locating tab for pairing with a locating slot of the beacon to provide proper orientation. The window has a removable cover to secure the beacon when the access window is not needed for inspection of the beacon.

摘要： A drill bit for use in horizontal directional drilling. In a preferred embodiment the drill bit has a connector section having a first axis of rotation. The connector section is used to connect the drill bit to a beacon housing for thrust and rotation therewith. A bit body is disposed next to the connector section and slopes from the connector section to a front nose section. The front nose section has a frontwardly facing surface that supports a plurality of cutting teeth. The front nose section and the bit body comprise a second axis of rotation about which the front nose section and the bit body are rotated. The first axis of rotation and the second axis of rotation are angularly offset at an offset angle of between four degrees and ten degrees.

摘要： An offset rock bit (12) has a steering face (28) and a shoe (30) provided by a recess formed into the steering face (28). A slot (66) formed into the shoe (30) for receiving a pull back adapter (50) in a centrally located position in the forward end of the offset rock bit (12). The pull back 5 adapter (50) has a pull back eye (52) with a central axis (62) which is aligned with a centrally disposed longitudinal axis (20) of the offset rock bit (12) and the tool string (10). This aligns the pull back eye (52) of the pull back adapter (50) with a borehole formed using the offset rock bit (12). The pull back adapter (50) also includes side edges (54, 56) which are configured for centering the pull back adapter (50) and pull back conduit within the borehole.
