ABSTRACT:
A roller reamer body is provided with junk receiving pockets that are downward extensions of the body cavities in which the rollers and their shaft mounting blocks are disposed. The slots have upwardly slidably openable or removable outside wall panels so that junk can be dumped from the slots while the reamer is still vertical in the drill string, making it unnecessary to disconnect the reamer to dump the junk.
