Installation Instructions
  • Well Bottom Check: Verify the previous bit for damage or diameter reduction. Ensure no hard particles (carbide or steel) remain at the well bottom.
  • Bit Inspection: Check cutters for abnormalities, ensure O-rings are in nozzle holes, and install nozzles as required.
  • Thread Preparation: Clean the bit's male or female thread and apply high-quality thread oil.
  • Makeup Process: Install the unloader on the bit and lower the drill string to contact threads.
  • Final Tightening: Place the bit and unloader in the turntable bushing; tighten threads according to recommended torque values.
