摘要： Bits configured for drilling rock that are of the type that includes a plurality of teeth supported in pockets that are on a cutting face that is driven to rotate. The pockets are configured to allow the teeth to passively rotate while in the pockets. The present disclosure provides a bit having hardfacing around the pockets and related methods.

摘要： Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as “torque-less” connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability.

摘要： A drilling apparatus is adapted for connection to a drill string such that the drill string rotates the drilling apparatus in a rotational cutting motion. The drilling apparatus includes a sonde housing having a distal end and a proximal end. The sonde housing includes a top platform positioned adjacent the distal end of the sonde housing and further includes a tongue positioned on the top platform. The drilling apparatus further includes a rotary cutting tool mounted to the distal end of the sonde housing.

摘要： A steerable reamer and method for use in horizontal directional drilling. The reamer includes a carrier frame rotatably coupled to a reaming body, a carrier frame housing slidably coupled to the carrier frame, and an hydraulic cylinder for tilting the carrier frame relative to the carrier frame housing. The reamer may also include sondes for monitoring the position and orientation of the reamer during operation or a laser guidance system for automatically steering the reamer along a pilot bore.
