Publication number: 20170087693Abstract: 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: December 14, 2016Publication date: March 30, 2017Inventors: KRISTIAN S. DRIVDAHL, MICHAEL D. RUPP, CHRISTIAN M. LAMBERT, CODY A. PEARCE

Patent number: 9267332Abstract: Impregnated drilling tools include elongated structures that provide enhanced properties. The drilling tools contain a diamond-impregnated cutting section that contains elongated structures made from carbon, glass, ceramic, and the like. The elongated structures can comprise tubes, fibers, or rods. In one or more implementations the elongated structures are nano-sized. The elongated structures can control the tensile strength and/or the erosion rate of the drilling tools to optimize the cutting performance of the tools. Additionally, the elongated structures may also weaken the cutting section in one or more implementations; thereby, allowing higher strength binders to be used. Such higher modulus binders can cost less and allow for tailoring of the cutting section to retain the diamonds for the desired amount of time. As the cutting section erodes, the elongated structures may also increase the lubricity at the face of the cutting section.Type: GrantFiled: August 24, 2011Date of Patent: February 23, 2016Assignee: LONGYEAR TM, INC.Inventors: Michael D.

Patent number: 7975785Abstract: Diamond-impregnated cutting tools including fibers and drilling systems incorporating such tools are described. The cutting tools contain a diamond-impregnated cutting portion that contains fibers made from carbon, glass, ceramic, polymer, and the like. The fibers may be used to both control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may also 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. Using the fibers allows the cutting tools to last longer and make them safer and more economical because they need to be replaced less often.Type: GrantFiled: November 24, 2008Date of Patent: July 12, 2011Assignee: Longyear TM, Inc.Inventors: Kristian S.

Patent number: 7695542Abstract: Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. The cutting tools contain a diamond-impregnated cutting portion that contains fibers made from carbon, glass, ceramic, polymer, and the like. The fibers can be in any form, including chopped and milled fibers. The fibers may also be coated with metal, ceramic, or other performance-enhancing coatings. The fibers may be used to both control the tensile strength control the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may also 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. And as the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion.Type: GrantFiled: November 30, 2007Date of Patent: April 13, 2010Assignee: Longyear TM, Inc.Inventors: Kristian S.
