Abstract: Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting elements may comprise multi-layer diamond tables that result in the formation of a shear lip during cutting. Earth-boring tools include such cutting elements. Methods of forming cutting elements may include selectively designing and configuring the cutting elements to form a shear lip. Methods of cutting a formation using an earth-boring tool include cutting the formation with a cutting element on the tool, and generating a shear lip at a wear scar on the cutting element. The cutting element may be configured such that the shear lip comprises diamond material of the cutting element.

Abstract: A rotary-type earth-boring drag bit with cutters oriented at varied rake angles and methods for designing such drag bits. Specifically, cutters that are located sequentially adjacent radial distances from a longitudinal axis of the drill bit have cutting faces that are oriented at rake angles that differ from one another. These cutters may be located on the same blade of the drag bit or on different blades of the drag bit. The rake angles at which the cutting faces of these cutters are oriented may be based, at least in part, on the relative radial distances these cutters are spaced from the longitudinal axis of the drag bit, on the vertical positions of these cutters along the longitudinal axis of the drag bit, or in response to actual or simulated evaluations of the use of the drag bit to drill a subterranean formation.

Abstract: Enhanced stabilization is provided for an eccentric reaming tool when a pilot borehole is undersized with respect to a following pilot stabilization pad (PSP). Alternatively, offset of a rotational axis of at least a portion of the assembly including the reaming tool is employed to accomplish stabilization of the reaming tool. In either case, a reamed diameter larger than a physical diameter of the reaming tool may be drilled. More specifically, an enlarged PSP relative to pilot bit diameter or PSP offset or even pilot bit offset is employed in order to engage a PSP with the wall of a pilot borehole of greater diameter than a physical diameter of the pilot bit. The PSP or pilot drill bit, or both, may be laterally offset, angularly offset, or a combination thereof in order to effect substantially continuous PSP contact with the pilot borehole wall.

Abstract: A rotary drag bit 10 comprises a bit body, the end face of which is embedded with cutters 150 of varying backrake angles. Specifically, cutters that are located at sequentially adjacent radial distances from a longitudinal axis of the drill bit have cutting faces that are oriented at rake angles that differ from one another. These cutters may be located on the same blade of the drag bit or different blades (20, figure 2). The rake angles at which the cutting faces are oriented may be dependent on the radial positions of the cutters, on their vertical distances along the axis, or in response to actual or simulated testing of the wear characteristics of the bit. Mathematical functions or a random number generator may also be used to determine the rake of the cutters.
