An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.

System and method for adjusting roller cone profile on hybrid bit

A reamer bit for use in earth boring operations comprising a body, four cutter mounts, rolling cutters on each mount, and cutting elements disposed on each cutter arranged so adjacent cutting swaths formed by the bit are created by cutting elements on cones of oppositely disposed cutter mounts. The swaths are generally curvilinear, wherein the outermost swaths are formed by cutting element rows on the outer portion of the cutters. The reamer bit can further comprise a pilot bit.
