Methods of forming earth-boring tools include assembling a plurality of head sections about a longitudinal axis to form a bit body, rotatably mounting a cutter to a cutter bearing shaft of each head section, and forming at least one groove on an outer surface of a bit leg of at least one head section, causing the at least one groove to extend along a curved path from a leading side of the bit leg to a trailing side of the bit leg between an upper sidewall and a lower sidewall.

Methods of forming earth-boring tools having features for affecting cuttings flow

An earth-boring bit has a bit body having a plurality of bit legs extending longitudinally therefrom, each bit leg comprising one or more groove regions formed along a laterally outer surface thereof. Each groove region comprises a fluid course for drilling fluid and cuttings to pass across the outer surface. A ridge may be disposed adjacent a lower edge of one or more of the groove regions. Each groove region may also be positioned at differing heights on the bit legs. Methods of forming earth-boring bits are also disclosed.

Earth-boring tools having features for affecting cuttings flow

An earth boring drill bit comprising cones, each cone having a land on its mid portion with at least two rows of compacts that are staggered with respect to adjacent compacts on another row. The compacts of these two rows may also have the same size. The compacts of these two inner rows are closer to each other than to any other compacts on the cone.
