Building on the proven design of our low profile and light weight raise drills, the Robbins 44RH C adds higher torque and thrust to a small diameter raise drill. The 44RH C is a versatile and high production raise drill, for raise requirements in the smaller diameter range.


Features & benefits

  • The sturdy worktable is available with a manual or a hydraulic wrenching system for fast and reliable pipe threading
  • The entire drive train features a hollow centre, enabling efficient transmission of any flushing media to clear the pilot hole
  • The Robbins raise drills apply to the well established and proven Atlas Copco Rig Control System (RCS) which adds reliability and user friendliness
