  • Application: Used for soft formation with low compressive strength and high drill-ability, such as shale, soft limestone, soft sandstone, gravel clay, soft dolomite, salt rock and coal seam, etc.
    Compressive strength: 50-90 Mpa
  • Lug protection (G feature): Hard-metal and wear resistant carbide were applied to shirttail and shirttail lip. The shirttail features a “ terraced design”, which increases escape area and the bailing velocity and decrease cuttings regrind and wear on the bit
  • Bearing structure (SGA): Bearing Type: RollerBall- RollerThrust Button/O ring seal
  • Shirttail lip protection (W): Radial surface of shirttail lip is processed by milling groove, and wear-resisting alloy is applied inside to strengthen shirttail lip protection and increase the bearing.
  • IADC: Code 515
  • Connection Thread: 6 5/8” API
  • Bit Diameter: 311 mm
  • Weight on Bit: 40000-72000lbs
  • Rotary Speed: 80-100pm
  • Air Pressure: 0.2-0.4MPa
