  • Pullback system for drilling tool
    Patent number: 10900294
    Abstract: A pullback system for installing product in a hole includes a rotary drill bit having a plurality of cutter elements, and a pullback device that is attachable to the rotary drill bit without disassembling the rotary drill bit or removing the rotary drill bit from a drill string. The pullback device includes a frame member and a plurality of anchor arms. Each anchor arm has a first end coupled to the frame member and a second end. Each anchor arm is configured to extend between adjacent cutter elements of the rotary drill bit. An attachment location can be used to attach product to the pullback device.

  • Dual rod directional drilling system
    Patent number: 10711520
    Abstract: A drill head includes a drive shaft that has an uphole end and a downhole end. The downhole end includes drive features that are torque transmitting and radial load bearing. The drill head also includes a coupling that includes drive features that are torque transmitting and radial load bearing. The drive features of the coupling are sized and shaped to mate with the drive features of the drive shaft. The coupling includes an axial fluid flow passage and a radial fluid flow passage. The radial fluid flow passage is in communication with the axial fluid passage, and fluid flow is permitted between the drive features of the drive shaft and the drive features of the coupling.
