Abstract
A roller reamer/stabilizer apparatus for use on a drill string assembly. The apparatus includes a reamer body which has a number of pockets formed in the body. A cutter assembly is anchored in each pocket. The cutter assembly includes a bearing pin on which two bearing blocks are mounted with a reamer cutter mounted in between the two bearing blocks. The entire cutter assembly is first assembled and is then placed in a corresponding pocket of the reamer body. The cutter assembly is secured within the pocket by means of pull pins which are inserted transversely through the reamer body so as to engage corresponding holes which are formed in the bearing blocks of the cutter assembly. The pull pins are secured by means of snap rings that can be easily removed so that the pull pins can then be retracted to permit the cutter assembly to be replaced after it is worn.
