摘要： A drill bit includes a plurality of continuous segments impregnated with diamond that are each mounted to form a corresponding blade. The regions between the blades define a plurality of fluid passages on the bit face. The blades extend radially outwardly to the gage. The continuous segments may be either straight or spiral in design. Furthermore, the design of the segments supports varying one or more of: diamond content, width, back rake angle and/or relief angle along a length of the segment.

摘要： A target cylinder and a method for testing a superhard component thereon. The target cylinder includes a first end, a second end, and a sidewall extending from the first end to the second end. At least one of the second end and the sidewall is an exposed portion that makes contact with the superhard component to determine at least one property of the superhard component. The exposed portion comprises at least one synthetic material having at least one of a compressive strength raging from about 12 kpsi to about 30 kpsi, an abrasiveness ranging from about 1 Cerchars to about 6 Cerchars, and an iron content ranging from about 5 percent to about 10 percent. Optionally, the exposed portion further comprises a second material interveningly positioned between or within the synthetic material in a predetermined and repeatable pattern.

摘要： A front face of a diamond table mounted to a substrate is processed to introduce a material which comingles with or semi-alloys with or partially displaces interstitial catalyst binder in a thermal channel to a desired depth. The material is selected to be less thermally expandable than the catalyst binder and/or more thermally conductive than the catalyst binder and/or having a lower heat capacity than the catalyst binder.

摘要： A cutter is configured with a diamond table made from a thin hard facing material layer of polycrystalline diamond bonded to a backing layer made from cemented tungsten carbide. The face of the diamond table includes a concavity formed with a curved shape wherein at least a portion of the face in a center of the cutter is recessed with respect to at least some portion of the face about the perimeter of the cutter. This concave curved shape is formed in the diamond table itself such that the diamond table has a varying thickness depending on the implemented concavity.

摘要： A sectorial force balanced drill bit, including conventional and bi-center drill bits, having the true center of rotation the same as, or about the same as, the bit mass axis. The bit mass axis is a longitudinal axis located off-center to the geometric axis of the bit and comprises the center of mass point. This balancing allows a greater longevity for the cutters. Additionally, a method for sectorially force balancing drill bits is provided. The method includes dividing the drill bit into one or more sections, calculating the magnitude and direction of the resultant radial imbalance force for the cutters of each section, adjusting the cutters and/or blades until the magnitude of the resultant radial imbalance force is about the same for each section and the direction of the resultant radial imbalance force for each section is about 2π/n, where n is the number of sections, from the adjacent section.
