    摘要: A rigid composite structure includes a tubular body made from a metallic material and having a first bore formed therein along a longitudinal axis, and one or more segments formed from a super hard material disposed within the first bore. Each segment has a hole formed in the center thereof, and the segments may be positioned end-to-end and adjacent to one another to align the center holes about the longitudinal axis and form a second bore. The segments can be held under compression within the first bore of the tubular body. The segments may be made of super hard materials such as natural diamond, synthetic diamond, polycrystalline diamond, single crystalline 10 diamond, cubic boron nitrate or other superhard composite materials which exhibit low thermal expansion rates and are generally chemically inert. The resultant rigid composite structure may possess higher tolerances to high pressures and high temperatures within the second bore.

    摘要: In one aspect of the invention, a superhard insert has a carbide substrate bonded to ceramic layer at an interface. The substrate has a generally frusto-conical end at the interface with a tapered portion leading to a flat portion. The central section of the ceramic layer may have a first thickness immediately over the flat portion of the substrate. The peripheral section of the ceramic layer has a second thickness being less than the first thickness covering the tapered portion of the substrate. The ceramic layer may be formed using HPHT technology.

    摘要: In one aspect of the invention a rotary drag bit has a bit body intermediate a shank and a working surface. The working surface has a plurality of blades converging at a center of the working surface and diverging towards a gauge of the working surface. At least one blade has a cutting element with a carbide substrate bonded to a diamond working end with a pointed geometry. The diamond working end has a central axis which intersects an apex of the pointed geometry such that the axis is oriented within a 15 degree rake angle.
