    Abstract: An earth-boring bit has a rotating cutter of a hybrid design. The bit has a bit body and a bearing shaft which is cantilevered downwardly and inwardly from the bit body. The cutter is mounted for rotation on the bearing shaft and has a plurality of cutting elements arranged in circumferential rows on the cutter. These rows include inner rows and a heel row. The cutting elements in the inner row are formed of a hard metal such as tungsten carbide and are pressed interferingly into apertures in the cutter. The heel row is made up of steel teeth formed on the cutter.

    Abstract: A cutter and a drill bit having such cutters for drilling subterranean formations including a superabrasive table formed on an end face of a supporting substrate, there being an interface between the table and the end face including a topographic configuration including at least one, and preferably a plurality of, annular arcuate surfaces centered about the centerline of the cutter and at least one recessed region or groove extending across a substantial portion of the end face. The topographic configuration of the end face is of an orientation and radial width sufficient to accommodate resultant loading of the cutting edge of the cutter throughout a variety of angles with vectors normal to the surface at a variety of angles such that at least one normal vector is aligned substantially parallel to the resultant loading on the cutting edge. The topographic configuration of the end face, preferably including at least one recessed portion, further provides a cutter in which the superabrasive table and the substrate are less prone to cracking, spalling, and catastrophic failure.

    Abstract: Drilling assemblies include a drill bit and a reamer apparatus in which the drill bit is configured to rotate in rotational direction about a longitudinal axis of a drill string and the reamer apparatus is configured to rotate in an opposite rotational direction about the longitudinal axis. Methods of forming a drilling assembly include configuring a drill bit to drill a subterranean formation when rotating in a counter-clockwise direction and configuring a reamer apparatus to ream a wellbore within the subterranean formation when rotating in a clockwise direction. Methods of drilling wellbores in subterranean formations include rotating a drill bit in a first rotational direction about a longitudinal axis of a drill string to drill a wellbore and rotating a reamer apparatus in an opposite rotational direction about the longitudinal axis of the drill string to ream the wellbore.
