    摘要： A cutting insert having an insert body with an upper surface. The upper surface of the insert body has an exterior cutting surface having an exterior cutting edge and an interior cutting surface having an interior cutting edge. The exterior cutting surface extends peripherally around and is coplanar with the upper surface of the insert body. The interior cutting surface is also coplanar with the upper surface of the insert body and is positioned within and is concentric with the exterior cutting surface. An exterior chip break separates the exterior cutting surface from the interior cutting surface.

    摘要： A bit tip insert on a bit/holder, tool, and/or pick for road milling operations that includes a body including a tip and a base subjacent the tip The bit tip insert also includes at least one heat transfer bore extending from a distal end and/or bottom of the body to a bore termination disposed within the base and/or the tip of the bit tip insert. The at least one bore of the bit tip insert is adapted to allow inward contraction when the overlay transfers heat into the base during operation.

    摘要： A polycrystalline diamond structure comprises a first region and a second region adjacent the first region, the second region being bonded to the first region by intergrowth of diamond grains. The first region comprises a plurality of alternating strata or layers, each or one or more strata or layers in the first region having a thickness in the range of around 5 to 300 microns. The polycrystalline diamond (PCD) structure has a diamond content of at most about 95 percent of the volume of the PCD material, a binder content of at least about 5 percent of the volume of the PCD material, and one or more of the layers or strata in the first region comprise and/or the second region comprises diamond grains having a mean diamond grain contiguity of greater than about 60 percent and a standard deviation of less than about 2.2 percent. There is also disclosed a method of making such a polycrystalline diamond structure.

    摘要： Rotary drill bits may include on or more cutting element assemblies which include a cutter and a mounting system. In one embodiment, the mounting system includes a housing, a first bearing component disposed within the housing, and a second bearing component associated with the cutting element. In certain embodiments, the bearing components may comprise a table of superhard material bonded with a substrate. In one or more embodiments, the bearing components may include bearing surfaces that are arcuate. For example, the bearing surfaces may be substantially spherical (a portion of a sphere). The bearing components may be arranged to act as a radial bearing as well as a thrust bearing for the cutting element, enabling the cutting element to rotate about a longitudinal axis of the cutter, relative to the housing, while also enabling the longitudinal axis of the cutter to be displaced (change angles) relative to the housing.
