    Abstract: Cutting elements for an earth-boring tool include a substrate base and a cutting tip. The cutting tip may include a first generally conical surface, a second, opposite generally conical surface, a first flank surface extending between the first and second generally conical surfaces, and a second, opposite flank surface. In some embodiments, the cutting tip includes a central axis that is not co-linear with a longitudinal axis of the substrate base. In some embodiments, the cutting tip includes a surface defining a longitudinal end thereof that is relatively more narrow in a central region thereof than in a radially outer region thereof. Earth boring tools include a body and a plurality of such cutting elements attached thereto, at least one cutting element oriented to initially engage a formation with the first or second generally conical surface thereof. Methods of drilling a formation use such cutting elements and earth-boring tools.

    Abstract: Geometric compensation techniques are used to improve the accuracy by which features may be located on drill bits formed using particle compaction and sintering processes. In some embodiments, a positional error to be exhibited by at least one feature in a less than fully sintered bit body upon fully sintering the bit body is predicted and the at least one feature is formed on the less than fully sintered bit body at a location at least partially determined by the predicted positional error. In other embodiments, bit bodies of earth-boring rotary drill bits are designed to include a design drilling profile and a less than fully sintered bit body is formed including a drilling profile having a shape differing from a shape of the design drilling profile. Less than fully sintered bit bodies of earth-boring rotary drill bits are formed using such methods.
