    Abstract: Methods of forming bit bodies for earth-boring bits include assembling green components that have been infiltrated, brown components that have been infiltrated, or fully sintered components that have been infiltrated, and sintering the assembled components. Other methods include isostatically pressing a powder to form a green body substantially composed of a particle-matrix composite material, and sintering or hot isostatic pressing the green body or brown body to provide a bit body having a desired final density. Methods of forming earth-boring bits include providing a bit body substantially formed of a particle-matrix composite material and attaching a shank to the body. The body is provided by pressing a powder to form a green body and sintering the green body. Earth-boring bits include a unitary structure substantially formed of a particle-matrix composite material. The unitary structure includes a first region configured to carry cutters and a second region that includes a threaded pin. Earth-boring bits include a shank attached directly to a body substantially formed of a particle-matrix composite material.

    Abstract: Methods of forming cutting element pockets in earth-boring tools include machining at least one recess (52) to define at least one surface of a cutting element pocket using a cutter (56) oriented at an angle to a longitudinal axis of the cutting element pocket. Methods of forming earth-boring tools include forming a bit body (50) and forming at least one cutting element pocket therein using a rotating cutter oriented at an angle relative to a longitudinal axis (60) of the cutting element pocket being formed. Earth-boring tools have a bit body comprising a first surface defining a lateral sidewall (55) of a cutting element pocket, a second surface defining an end wall (66) 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 (18) to abut against an area of the lateral sidewall and end wall of the pocket.
