Abstract: A superabrasive element includes a substrate and a superabrasive table bonded to the substrate, the superabrasive table including a polished surface having a polished finish, the polished surface extending over at least a central, apical region of the superabrasive table, and an unpolished surface including an unpolished finish, the unpolished surface surrounding a majority of the polished surface. A method of manufacturing a superabrasive element includes providing a superabrasive element having a substrate and a superabrasive table bonded to the substrate and polishing at least a central, apical region of the superabrasive table to form a polished surface, without polishing an unpolished surface of the superabrasive table, the unpolished surface surrounding a majority of the polished surface.

Abstract: An example PCD body includes a top surface, a bottom surface opposite the top surface, and at least one lateral surface extending between the top surface and the bottom surface. The PCD body includes one or more threads that are configured to allow the PCD body to be threadedly attached to a component, such as a substrate, a drill bit body, or a support ring. In an embodiment, the one or more threads may be formed on at least a portion of the lateral surface.

Abstract: Embodiments of the invention are directed to roll assemblies configured to exhibit improved wear resistance of stud elements. Accordingly, the roll assemblies of may improve and/or increase the useful life of high pressure grinding roll apparatuses. In an embodiment, one or more stud elements may include superhard material, which may provide superior wear resistance characteristics and may increase the useful life of the rolls assemblies and high pressure grinding roll apparatuses.
