Publication number: 20100089660Abstract: Implementations of the present invention include drilling tools having axially-tapered waterways that can increase flushing and bit life, while also decreasing clogging. According to some implementations of the present invention, the waterways can be radially tapered in addition to being axially tapered. The axially-tapered waterways can include notches extending into the cutting face of the drilling tools and/or slots enclosed within the crown of the drilling tools. Implementations of the present invention also include drilling systems including drilling tools having axially-tapered waterways, and methods of forming drilling tools having axially-tapered waterways.Type: ApplicationFiled: December 15, 2009Publication date: April 15, 2010Applicant: LONGYEAR TM, INC.Inventors: Cody A. Pearce, Christian M. Lambert, Michael D. Rupp

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. Drivdahl, Michael D. Rupp

Publication number: 20100012386Abstract: Core drill bits with long crown heights are described herein. The core drill bits have a series of slots or openings that are not located at the tip of the crown and are therefore enclosed in the body of the crown. The slots may be staggered and/or stepped throughout the crown. As the cutting portion of the drill bit erodes through normal use, the fluid/debris notches at the tip of the bit are eliminated. As the erosion progresses, the slots become exposed and then they function as fluid/debris ways. This configuration allows the crown height to be extended and lengthened without substantially reducing the structural integrity of the drill bit.Type: ApplicationFiled: September 25, 2009Publication date: January 21, 2010Applicant: LONGYEAR TM, INC.Inventors: K. Shayne Drivdahl, Michael D. Rupp

Publication number: 20100008738Abstract: 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: September 17, 2009Publication date: January 14, 2010Applicant: LONGYEAR TM, INC.Inventors: Kristian S.

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: ApplicationFiled: November 24, 2008Publication date: March 19, 2009Applicant: LONGYEAR TM, INC.Inventors: Kristian S.

As the erosion progresses, the slots become exposed and then they function as fluid/debris ways. This configuration allows the crown height to be extended and lengthened without substantially reducing the structural integrity of the drill bit. And with an extended crown height, the drill bit can last longer and require less tripping in and out of the borehole to replace the drill bit.Type: ApplicationFiled: December 14, 2006Publication date: June 19, 2008Inventors: K.
