Abstract

See full text

Methods for forming fixed-cutter earth-boring drill bits include retrieving a forged steel drill bit body from an inventory of substantially identical forged steel drill bit bodies including fixed blades and junk slots between the fixed blades. Cutter pockets are formed in the blades. Nozzle holes are formed in the drill bit body to provide fluid communication from an interior of the forged steel drill bit body to the junk slots. Additional methods include forging first and second steel drill bit bodies substantially identical in shape and configuration, forming first cutter pockets in the first steel drill bit body in a first configuration, and forming second cutter pockets in the second steel drill bit body in a second, different configuration.
