Low Stress Drilling (LSD)


The HOC Low Stress Drilling Hole Opener features a unique one-cutter design that eliminates the risk of cone pocket failure and excessive side load, while
assuring a full gauge run under the most adverse hole conditions.

Features and Benefits

  • Fixed diameter.
  • Operates with significantly lower torque requirements than conventional hole openers because of its single nutating (wobble) Sealed Bearing cutter.
  • Integral body, coupled with extremely large, well-lubricated bearing surfaces in the cutter, allows for significant weight to be applied when drilling
    harder formations.
  • Cutting elements are located on the top and bottom sides of cutter, allowing the hole opener to backream as well.
