Abstract
This invention is directed to a stabilizer-reamer which is useful in drilling oil wells and holes in mineral formations. The stabilizer-reamer extends the life of the drill bit by maintaining the diameter of the hole to original specifications. The stabilizer-reamer comprises a stabilizer portion which reduces excessive lateral movement of the drill bit, a reamer portion which reams away undersize portions of the walls of the hole and a rock chip grinding portion which breaks down oversize rock chips in the hole.
