    摘要： A drill bit for drilling subterranean formations comprising a drill bit body including a group of primary cutting elements comprising a first primary cutting element and a second primary cutting element radially spaced apart from each other along a first radial axis. The drill bit body further including a group of backup cutting elements comprising a first backup cutting element in a secondary cutting position relative to the first primary cutting element and a second backup cutting element in secondary cutting positions relative to the second primary cutting element, wherein the first and second backup cutting elements are radially spaced apart from each other along a second radial axis different than the first radial axis and comprise a difference in cutting characteristic relative to each other of one of a backrake angle and a siderake angle.

    摘要： Earth-boring tools comprise a body having a face at a leading end. A plurality of cutting elements are disposed over the face and configured as a plurality of kerfing pairs comprising two or more cutting elements disposed at substantially the same radial position relative to a bit axis, wherein each of the at least two cutting elements follows substantially the same cutting path when the bit is rotated about its axis. Earth-boring tools are further configured so that a summation of a lateral force generated during drilling by each cutting element of the plurality of cutting elements is directed toward a side of the body.

    摘要： Method of making an earth-boring tool comprise forming a body comprising a face including a plurality of radially extending blades thereon and a cone region, a nose region, and a shoulder region. A plurality of cutting elements may be disposed on the blades at least in the cone region, the nose region, and the shoulder region. Some of the cutting elements may be configured to form kerfing pairs comprising at least two cutting elements disposed on different blades of the plurality of radially extending blades at least substantially at the same radial position from a central axis of the body. At least one of the blades and orientations and exposures of the plurality of cutting elements may be configured so that a summation of a lateral drilling force generated by each cutting element of the plurality of cutting elements is directed toward a lateral side of the body.
