    Abstract: A plurality of passages transmit fluid end to end in the reamerstabilizer body. Individual cutters are mounted on hollow shafts affixed to the reamer-stabilizer body. A circular passage transmits fluid to the center of the hollow shafts. Holes connect the outside of each shaft with the hollow central portion. Spiral grooves are located longitudinally on the inside diameter of the cutter.
