The CLAW™ is the most powerful motor in the nDURANCE® drilling motor series. It features industry leading even wall power sections coupled with a ruggedized bearing section to deliver greater horsepower and achieve outstanding drilling performance.


  • The CLAW delivers 50-90% more power than conventional motors
  • The CLAW’s proprietary design accommodates higher flow rates compared to conventional motors
  • The CLAW’s shorter bit to bend (B2B) design yields higher build rates and allows for rotation of motor through higher doglegs, enabling one-run verticals, curves, and laterals


  • Formations with poor build tendencies
  • Hard, aggressive, and unconsolidated formations
  • Monobore wells
  • Where operators want to leverage a rig’s higher pumping power


  • Increased horsepower and torque
  • Greater reliability and fewer trips
  • Greater weight on bit (WOB) capacity
  • Enhanced bit life
  • Greater yield strengths: driveline components constructed from ultra-high strength materials with yield strengths up to 200,000 psi
