Abstract
A bearing block (40) is provided that may be used with a drag bit body (1 0) or frame to limit depth of cut of cutters on a bit. The bearing block is designed so that it may be interchangeably replaced or repaired without nece ssitating alteration to a standardized bit frame. The interchangeable bearin g block may be used to provide a target depth of cut (TDOC) and/or a selecte d contact or rubbing area (32) to support weight on bit and limit depth of c ut (DOC) for improving drilling performance of a bit. The interchangeable be aring block brings manufacturing selectability by providing. a customizable product in terms of depth of cut selection and cutter penetration control fo r different formations, which is suitable for use with a common bit frame. A rotary drill bit assembly, a unitary cone insert bearing block for a drill bit, and a bit frame are also provided.
