Patent number: 10107040Abstract: An earth-boring tool includes primary and secondary cutting elements mounted to a tool body. The secondary cutting elements define a secondary cutting profile. The secondary cutting profile is recessed relative to the primary cutting profile, which is defined by the primary cutting elements. In an unworn condition, the primary cutting elements engage and cut a formation material while the secondary cutting elements do not. Each secondary cutting element includes a flat surface oriented at an angle relative to a longitudinal axis thereof and extending between a front cutting face and a peripheral side surface thereof. The secondary cutting elements are oriented on the tool body such that a surface area of the flat surface thereof will engage the formation material at least substantially simultaneously when the primary cutting elements reach a worn condition. Methods of forming the earth-boring tool and methods of using the earth-boring tool are also disclosed.Type: GrantFiled: November 11, 2015Date of Patent: October 23, 2018Assignee: Baker Hughes, a GE company, LLCInventors: Kenneth R.

Patent number: 8079429Abstract: Geometric compensation techniques are used to improve the accuracy by which features may be located on drill bits formed using particle compaction and sintering processes. In some embodiments, a positional error to be exhibited by at least one feature in a less than fully sintered bit body upon fully sintering the bit body is predicted and the at least one feature is formed on the less than fully sintered bit body at a location at least partially determined by the predicted positional error. In other embodiments, bit bodies of earth-boring rotary drill bits are designed to include a design drilling profile and a less than fully sintered bit body is formed including a drilling profile having a shape differing from a shape of the design drilling profile. Less than fully sintered bit bodies of earth-boring rotary drill bits are formed using such methods.Type: GrantFiled: June 4, 2008Date of Patent: December 20, 2011Assignee: Baker Hughes IncorporatedInventors: Redd H.

Patent number: 6568491Abstract: A graphite or silicate plug is coated with a refractory metal and positioned in the cutter pocket of a steel bodied bit as molten hardfacing material is applied to the bit surface under high temperature conditions. The refractory metal cooperates with the hardfacing material to act as a wetting agent that draws the hardfacing material into intimate contact with the body of the displacement plug. The plug is removed leaving a composite pocket opening formed by the steel body and the hardfacing material. A PDC cutter inserted into the composite pocket opening closely adheres to the sides of the opening to reduce the gap between the cutter and the hardfacing material to hereby minimize the effects of erosion in the area of the gap. The wetting material on the displacement plug permits the hardfacing material to flow into and remain in position immediately adjacent the displacement body and in the small surface area between adjacent cutter pockets.Type: GrantFiled: June 4, 2001Date of Patent: May 27, 2003Assignee: Halliburton Energy Services, Inc.Inventors: Oliver Matthews, III, David P.
