CUSTOM HOLE OPENERS

Atlas Rock Bit's Custom Hole Openers are designed to handle big-hole driller projects, offshore well conductor holes, and other drilling needs where speed and reliability are important.

  • "Nail-Lock" retained nozzles can be changed quickly and easily for matching particular pump capacities or hydraulics programs.
