Europe style for Forged Drill Rod - Steel Tooth Rotary Drill Bit – TDS
Europe style for Forged Drill Rod - Steel Tooth Rotary Drill Bit – TDS Detail:
Tricone bit is an important tool for oil drilling, its work performance will directly affect the quality of drilling, drilling efficiency and drilling costs. Oil drilling and geological drilling is the most used or cone bit. The cone bit has the effect of rocking, crushing and shearing the formation rock in rotation, so the cone bit can be adapted to soft, medium and hard layers. Especially in the jet cone bit and long nozzle after the emergence of cone bit, the cone drill bit drilling speed greatly improved, is the history of the development of cone bit a major revolution. The cone bit can be divided into teeth (tooth) by tooth type, tooth (bit) (tooth set inlaid with carbide teeth) cone bit; according to the number of teeth can be divided into single cone, double , Three-cone and multi-cone bit. At home and abroad use the most, the most common is the Tricone bit.
