Railhead EXTReam™

For cobble, soft to medium rock & hard rock

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.

Features:

  • Field replaceable teeth
  • Pointed teeth for softer rock & rounded teeth for harder rock
  • No moving parts, no bearings to fail
  • 8", 12" and 16" Pulling Eye threaded onto shaft and welded
  • 6" has removable Pulling Eye, through fluid hole and can be pulled in tandem
