Patent number: 10227832Abstract: 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.Type: GrantFiled: March 14, 2017Date of Patent: March 12, 2019Assignee: Vermeer Manufacturing CompanyInventors: Michael D. Langenfeld, Randy R. Runquist

Patent number: 9732560Abstract: A drilling apparatus including a rotary cutting tool having a proximal end and a distal end and further defining a rotary axis generally extending between the proximal and distal ends. The rotary cutting tool includes a proximally directed face located between the proximal and distal ends that face mainly in a proximal direction. The rotary cutting tool also includes an angled mounting face that extends between the proximally directed face and the proximal end. The angled mounting face is angled relative to the proximally directed face and the rotary axis where one of a mounting aperture and a mounting protrusion are provided at the proximally directed face. The one of the mounting aperture and the mounting protrusion have a mounting depth that extends generally in the direction of the rotary axis. The distal end includes a feature that is configured for at least one of cutting and grinding.Type: GrantFiled: August 15, 2014Date of Patent: August 15, 2017Assignee: Vermeer Manufacturing CompanyInventors: Christopher R.

Publication number: 20150114724Abstract: A drilling apparatus can include a sonde housing that is elongated along a central longitudinal axis. The sonde housing has a length that extends along the central longitudinal axis from a proximal end of the sonde housing to a distal end of the sonde housing. The proximal end of the sonde housing is adapted for connection to a drill string and the distal end of the sonde housing includes a distal end face. The sonde housing further defines first and second sonde-housing fluid-delivery passages. The first and second sonde-housing fluid-delivery passages extend fluidly separately from one another throughout substantially an entire length of the sonde housing. The drilling apparatus can also include a rotary cutting tool that mounts to the distal end of the sonde housing. The rotary cutting tool can further define distinct first and second cutting-tool fluid-delivery passages. The first sonde-housing fluid-delivery passage can be in fluid communication with the first cutting-tool fluid-delivery passage.Type: ApplicationFiled: January 6, 2015Publication date: April 30, 2015Inventors: Randy R.

Patent number: 8235142Abstract: A method and system for controlling a horizontal directional drilling machine having a boring tool. A rate of rotation and a rate of thrust are selected by an operator. Controls allow an automatic boring operation mode to be initiated to maintain the selected rate of rotation and thrust without further input from the operator. Periodically, when the rotation and thrust are interrupted, such as to modify the drill string, the automatic boring operation mode is interrupted. The automatic boring operation mode may be resumed without requiring the operator to select the rate of rotation and rate of thrust. The rate of rotation is resumed before the rate of thrust to reduce drill string shock loads and increase drilling performance.Type: GrantFiled: May 24, 2010Date of Patent: August 7, 2012Assignee: Vermeer Manufacturing CompanyInventors: Robin W. Carlson, Randy R. Runquist
