Publication number: 20140311809Abstract: Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. A matrix is formed that contains fibers made from carbon, glass, ceramic, polymer, and the like. The matrix is then sintered to form a cutting portion of a drill bit. The type and concentration of the fibers can be modified to control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may be added to the cutting section to weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting portion for the desired amount. As the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion.Type: ApplicationFiled: June 30, 2014Publication date: October 23, 2014Inventors: KRISTIAN S. DRIVDAHL, MICHAEL D. RUPP

Patent number: 8616303Abstract: A down-the-hole assembly includes a housing having a central axis and a mechanical gear box positioned within the housing. The mechanical gear box is coupled to the housing such that rotation of the housing at a first rotational rate provides a rotary input to the mechanical gear box. A rotary cutting bit is coupled to the mechanical gear box. The mechanical gear box is configured to rotate said rotary cutting bit at a second rotational rate in response to that rotary input from the housing. The second rotational rate is greater than the first rotational rate. The mechanical gear box is also further configured to cause the rotary cutting bit to orbit about the central axis of the housing.Type: GrantFiled: February 9, 2011Date of Patent: December 31, 2013Assignee: Longyear TM, Inc.Inventors: Michael D.
