The solid body design of Railhead’s EXTReam ™ makes it a true horizontal rock reamer. A variety of different size nozzles and plugs are available to re-configure the water ports based on the volume of mud being pumped and the conditions encountered during the pilot bore. The EXTReam ™ works best with low pullback pressure and low rotational torque.
