ABSTRACT:
The roller reamer drilling tool includes an elongated body having a fluid circulation bore. A plurality of roller reamer units are mounted circumferentially about the body and are capable of being installed as units within a series of pockets machined within the body. The pockets include a central pocket to receive the roller reamer, a lower bearing block pocket and an upper bearing block pocket which has a width greater than the width of the roller so that the roller can be installed through the upper bearing block pocket, which allows the installation of the roller, shaft and upper bearing block as a unit.
