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
