17 1/2"IADC 117 water well drilling steel tooth tricone bit

17 1/2"IADC 117 water well drilling steel tooth tricone bit

  Product specifications  IADC117G Diameter 17 1/2"(444.5mm) Bearing type Rubber Sealed Bearings Tooth Type Milled Tooth Circular Type mud Thread Connection 7 5/8 API REG Wheel diameter protection (diameter retention) Available Shirttail Protection Available Operating parameters    RPM 150-80 WOB 035-0.8 Application Formation very soft formations with low compressive strength,    Introduction Milled tooth(MT) tricone bit: it is suitable for very soft formation with high drilling efficiency and excellent diameter protection ability. According to different formation hardness and drill ability, the mill tooth bit can machine different height and width teeth on the outer line of the cone ,and weld a layer of WC wear-resistant material on the surface of theteeth to enhance wear resistance.   Features 1.Bearing Structure: High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed. 2.Cutter Structure： Steel tooth structure effectively improving the wearing resistance of the teeth and greatly increasing the rate of penetration. 3.Gauge protection: more tungsten carbide inserts are placed in the gauge to reduce the wear in the abrasive formation. It can protect gauge and increases the stability and life of the bit. 4.Nozzle：These nozzles are much sturdier and provide greater flow capacity and maximize fluid distribution to the cones.   Technology 1.Seal and Lubrication: The bearing seal is adapting the high quality HNBR O-ring. The best seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.  2.Six-point Gauge Stability: The design delivers near six-point contact with the borehole wall for unequalled bit stability that protects the cutting structure from damaging lateral blows 3.Motor hardfacing: Tungsten carbide particle hardfacing is applied liberally along the shirttail and extended up the leading edge of the bit leg for additional protection in high-speed, directional or abrasive applications   Application Very soft formations with low compressive strength,such as clay/shale/ sand stone/soft limestone.etc. Popular Models Operating parameters
