Earth-boring tools comprise a shank comprising a distal connector including a set of threads thereon and a bit body comprising a shank connector, also comprising at least one set of threads thereon. The set of threads on the distal connector and the at least one set of threads on the shank connector are at least substantially bound together. Methods of forming such earth-boring tools are also disclosed, as well as methods of securing a bit body of an earth-boring tool to a shank.
System, Method, And Apparatus For Reactive Foil Brazing Of Cutter Components For Fixed Cutter Bit
A reactive foil is used to assemble the components of rock bit cutters and to affix cutting elements to rock bit bodies. A small pulse of localized energy ignites the foil in a fraction of a second to deliver the necessary amount of heat energy to flow solder or braze and form a strong, true metallic joint. The reaction in the foil may be activated using optical, electrical, or thermal sources.
Hardfacing Materials Including Pcd Particles, Welding Rods And Earth-Boring Tools Including Such Materials, And Methods Of Forming And Using Same

Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 10/00 C23C 16/27
US Classification:
175374, 4272497
Abstract:
Hardfacing materials include particles of polycrystalline diamond (PCD) material embedded within a matrix material. The PCD particles comprise a plurality of inter-bonded diamond grains. Material compositions and structures used to apply a hardfacing material to an earth-boring tool (e. g. , welding rods) include PCD particles. Earth-boring tools include a hardfacing material comprising PCD particles embedded within a matrix material on at least a portion of a surface of a body of the tools. Methods of forming a hardfacing material include subjecting diamond grains to elevated temperatures and pressures to form diamond-to-diamond bonds between the diamond grains and form a PCD material. The PCD material is broken down to form PCD particles that include a plurality of inter-bonded diamond grains. Methods of hardfacing tools include bonding PCD particles to surfaces of the tools using a metal matrix material.
Methods Of Forming Polycrystalline Diamond Cutting Elements, Cutting Elements, And Earth-Boring Tools Carrying Cutting Elements
Methods of forming polycrystalline diamond elements include forming a polycrystalline diamond compact comprising a cavity in a surface thereof. A catalyst is at least substantially removed from the polycrystalline diamond compact, and the polycrystalline diamond compact is secured to a supporting substrate. Cutting elements include a diamond table formed with a cavity in a back side surface thereof and a supporting substrate secured to the back side surface of the diamond table. Earth-boring tools comprise a bit body carrying one or more cutting elements including a diamond table, a supporting substrate and an adhesion layer comprising a superhard material between and bonding the cutting table and the supporting substrate.
Bonding Agents For Improved Sintering Of Earth-Boring Tools, Methods Of Forming Earth-Boring Tools And Resulting Structures
Methods for forming earth-boring tools include providing a metal or metal alloy bonding agent at an interface between a first element and a second element and sintering the first element, the second element, and the boding agent to form a bond between the first element and the second element at the interface. The methods may be used, for example, to bond together portions of a body of an earth-boring tool (which may facilitate, for example, the formation of cutting element pockets) or to bond cutting elements to a body of an earth-boring tool (e. g. , a bit body of a fixed-cutter earth-boring drill bit or a cone of a roller cone earth-boring drill bit). At least partially formed earth-boring tools include a metal or metal alloy bonding agent at an interface between two or more elements, at least one of which may comprise a green or brown structure.

Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 10/43
US Classification:
166378, 175430, 175431
Abstract:
Earth-boring tools include combinations of shearing cutting elements and gouging cutting elements on a blade of the earth-boring tools. In some embodiments, a gouging cutting element may be disposed adjacent to a shearing cutting element on a blade of an earth-boring tool. Methods of forming earth-boring tools include providing such combination of at least one shearing cutting element and at least one gouging cutting element on a blade of an earth-boring tool.
Earth-Boring Tools And Cutter Assemblies Having A Cutting Element Co-Sintered With A Cone Structure, Methods Of Using The Same

International Classification:
E21B 10/36
US Classification:
175 61, 175263, 175425
Abstract:
Methods of forming cutter assemblies for use on earth-boring tools include sintering a cone structure to fuse one or more cutting elements thereto. In some embodiments, one or more green, brown, or fully sintered cutting elements may be positioned on a green or brown cone structure prior to sintering the cone structure to a final density. Cutter assemblies may be formed by such methods, and such cutter assemblies may be used in earth-boring tools such as, for example, earth-boring rotary drill bits and hole openers.
