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.

Attack inserts with differing surface finishes, assemblies, systems including same, and related methods

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.

Polycrystalline diamond bodies including one or more threads, apparatuses including the same, and methods of forming and using the same

Various drill bits, drilling systems and related methods are provided. In one embodiment, a drill bit comprises a bit body having a face and a shank, at least one insert having a convex engagement surface coupled with the face and at least one wear insert coupled with the shank. In one particular embodiment, the at least one wear insert may be positioned immediately adjacent a coupling end of the shank. The at least one wear insert may include a superabrasive table which may be bonded with a substrate. The at least one wear insert includes a wear surface defined in the superabrasive table. In one embodiment, the superabrasive table may comprise polycrystalline diamond. Similarly, the inset having a convex engagement surface may include a superabrasive material, such as polycrystalline diamond, bonded with a substrate. Such a drill bit may be used, for example, in a top hammer percussion drilling operation.

Embodiments described herein relate to material-removal systems and cutting tools that may be used in the material-removal systems. More specifically, for example, the material-removal systems, and particularly the cutting tools thereof, may engage and fail target material. In some instances, the material-removal systems may be used in mining operations.

Material-removal systems, cutting tools therefor, and related methods

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.
