Abstract: A drill bit in one aspect includes a cutting device on a selected section of the drill bit, which cutting device is configured to cut formation on the high side of a wellbore during drilling of the wellbore. In one aspect, the cutting device comprises a cutting element disposed on a substantially non-rotating member placed around the selected section. In another aspect, the selected section may be a gage section of the drill bit.

Abstract: Drill bits for subterranean drilling comprising a bit body including at least one blade that includes a blade face comprising a contact zone and a sweep zone are disclosed. In particular, drill bits including at least one blade that extends at least partially over a nose region of the bit body, a shoulder region of the bit body and a gage region of the bit body and that include a sweep zone that rotationally trails the contact zone with respect to a direction of intended bit rotation about a longitudinal axis of the bit body and include a contact zone that defines a range of about 90% to about 30% of the blade face surface area is disclosed. Additionally, drill bits comprising a sweep zone located at least partially within a gage region are disclosed. Also, methods of off-center drilling and methods of manufacturing drill bits are disclosed.
