Abstract
A method of manufacturing, assembling, configuring, and/or using a hybrid drill bit is disclosed. An illustrative example includes inserting a rolling cutting structure into a central bore of a bit body through an upper connector section of the bit body toward a lower end portion of the bit body. The bit body has a rotational axis and a plurality of blades at the lower end portion. The upper connector section is configured to be coupled to a lower end of a drill string. Each of the plurality of blades extends radially from the bit body about the rotational axis at the lower end portion and includes a plurality of cutters embedded therein.
