    Abstract: Earth-boring rotary drill bits including a bit body attached to a shank assembly at a joint. In some embodiments, the joint may be configured to carry at least a portion of any tensile longitudinal and rotational load applied to the drill bit by mechanical interference at the joint. In additional embodiments, the joint may be configured to carry a selected portion of any tensile longitudinal load applied to the drill bit. Methods for attaching a shank assembly to a bit body of an earth-boring rotary drill bit include configuring a joint to carry at least a portion of any tensile longitudinal and rotational load applied to the drill bit by mechanical interference. Additional embodiments include configuring a joint to carry a selected portion of any tensile longitudinal load applied to the drill bit by mechanical interference.

    Abstract: Methods of forming cutting element pockets in earth-boring tools include machining at least one recess to define at least one surface of a cutting element pocket using a cutter oriented at an angle to a longitudinal axis of the cutting element pocket. Methods of forming earth-boring tools include forming a bit body and forming at least one cutting element pocket therein using a rotating cutter oriented at an angle relative to a longitudinal axis of the cutting element pocket being formed. Earth-boring tools have a bit body comprising a first surface defining a lateral sidewall of a cutting element pocket, a second surface defining an end wall of the cutting element pocket, and another surface defining a groove located between the first and second surfaces that extends into the body to enable a cutting element to abut against an area of the lateral sidewall and end wall of the pocket.

    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.
