Drill Bit

FJ Series Metal Sealed Bearing Bit

  • New processes of head bearing hardfacing and cone bearing silver plating are used to improve the load capacity, anti – galling ability and stability of the bearing.
  • Various shapes of inserts can be equipped on this series of bits, including scoop inserts, wedge inserts, conical – spherical inserts and double spherical in serts, ect.
  • Drilling process & formation and bit are efficient integrated by scientific insert shape selection to realizesafety and high efficient drilling.

FR Series Rubber Sealed Bearing Bit

  • Journal bearing. Hardfaced head bearing surface. Inner hole of cone is silver – plated. The load capacity and seizure resistance of the bearing is greatly improved.
  • ring seal is made of the more wear resistant and high saturated buna – N with the increased seal section and precisely designed scaling flange in the cone sealing area has increased the reliability of the seal.
  • All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.
  • High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shape compacts. For steel tooth bit, the tooth surface is hard faced with new type of wear resistant material and thus has extended working life of the cutting structure while still maintaining high ROP.

ZS 1904 IADC: S122

  • Bit characteristics: suitable for soft and medium soft layers, high abrasive formation.
  • Bit performance: blade less, chip space is large, and the use of good abrasion resistance, strong anti impact properties of high quality PDC films, is conducive to the three – dimensional rotating spiral blade runner injection, fast cutting exhaust, improve the service life of drill bits. Using swirl channel change bottom flow field, avoid duplication of cuttings, greatly improve the drilling speed.
