Beijing superior drilling equipment co., ltd is a comprehensive enterprise set pdc bits, tricone bits production sales. The company was founded in 1989, covers an area of 27 acres, is located in the vast expanse of hebei plain, is located in the central area of the major oil fields, unique geographical location, has a strong design, development and production capacity. Optional features c center nozzle: center jet can avoid bit balling, eliminate resorting area of fluid at bottom hole, expedite upward flow of the cuttings and improve rop. It is suitable for drilling in soft to medium soft formations with low compressive strength and high drillability. D gage protection by diamond enhanced cutters on head o.d the gage protection is significantly reinforced by adding diamond enhanced gage compacts on the head od. Bit with this feature is suitable for drilling in directional and horizontal well with high abrasive formation. e extend double nozzle the hydraulic system of extended double nozzle can expedite upward flow of cutting ,  reduce regrinding of the formation and eliminate resorting area of fluid at bottom hole to achieve effective drilling. g head od enhancement special insert are strategically arranged on head od to reduce effectively wear of the head and improve bit's gage protection in abrasive formation or directional and horizontal wells. Improved gage protection can extend service life of the bit. h gage protection by diamond enhanced cutters on cone diamond compacts arranged in heel row or gage row for the cone can enhance gage protection and increase its working life. It is suitable for drilling in high abrasive formation, hard or extreme hard formations.

Cutting structure:the durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit. Gauge structure: multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hard-facing on the shirttail increase gauge holding capacity and bearing life.

A.1. Journal bearing. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improved. 2. O ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal. 3. The bit bearing can be ball locked or ring locked. Bit with ring lock bearing can stand high weight on bit and bit with ball lock bearing can be applied to high rotary speed drilling. 4. 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. 5. New type of grease that can sustain high temperature up to 250C is utilized. 6. 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 shaped compacts. For steel tooth bit, the tooth surface is hardfaced with new type of wear resistant material and thus extended working life of the cutting structure while still maintaining high ROP.
