Abstract
A drilling stabilizer having a body and a plurality of blades integrally cast from tungsten carbide particles bound together with a heated metal binder, for use in drilling oil and gas wells, has a first box end and a second pin end at the distal end of the stabilizer. A plurality a PDC cutters are mounted on the top end of the stabilizer to allow the stabilizer to be used as a reamer when pulling the stabilizer out of the borehole. A steel tube is formed within the interior of the stabilizer in the molding process and which allows the pin end to have steel threads and the box end to also have steel threads to facilitate the makeup of the stabilizer with either the steel threads of a drill bit or the steel threads of joints of drill pipe.
