Structure Features:

The teeth used in tricone rock bits are made of high quality cemented carbide alloy which possesses high strength and wear-resistance, and the shapes of teeth are designed to drill formations and break rock efficiently. Selected optimal teeth configurations allow the bits to have maximum coverage of bottom,as well increasing the drainage intervals of cuttings between cones,so that it can drill more smoothly and maintain high penetration rates.

The bearings used in tricone rock bits are made of excellent bearing alloy,and machined and heat-treated with advanced technique and equipment,so as to enable the bearings to have greater loading strength and higher wear-resistance,suitable for faster rotary speed, and have longer service life.

The tritons rock bits utilize air as drilling fluids. The compressed air, through the cooling air channel, is led into bearings to cool them,and,through the cooling air channel, is led into bearings to cool them,and,through nozzles, to blow the rock cuttings out of the hole. The reasonable angle of jet nozzle does not only increase the drainage rate of cuttings, but also minimize the erosibility of ejects against the cones.

To enhance the gage protection of bit, tritons tock bits is designed to achieve multi-protections of bit gage. The flat-ended tungsten carbide compacts are installed into the blackface of legs and the tungsten carbide particles are hard faced on the shirttail area of leg top to retard the gage wear.
