API Drill Bit Structural characteristics

　　1.The thrust bearing is made of materials with high wear resistance, high hardness, and high temperature resistance to improve its load-bearing capacity.

　　2.The air-cooling system can improve the air circulation conditions in the bearing cavity andreduce the temperature inside the bearing cavity.

　　3.The cutting structure adopts circular arc hard alloy ball teeth to improve compressive strengthand wear resistance and reduce tooth breakage rate.

　　4.The palm back is equipped with hard alloy teeth and welded with wear-resistant alloy toreduce wear on the palm back and extend bearing life.

　　Drill Bits from Shengtian Group are produced and processed according to , with the materials of steel grade including J55, K55, N80, N80-1, N80-Q, L80, P110 and so on. The couplings have three types, namely STC LTC and BTC. By numerically controlled lathe and import molding cutter, the processing of thread can be finished in one time, which ensures its commonality and interchangeability. We have complete testing abilities, adopting a whole set of single testing apparatus of thread, including tape, pitch, tooth depth, profile and so on. Our products have already passed the identification of the Quality Testing and Inspection Centre of Oil Pipe of CNPC (China National Petroleum Corporation).
