Product Description
Classification of tricone bit:
1. Bearing type: rolling bearing and sliding bearing
2. Seal type: rubber seal and metal seal
3. According to the fixed way of tooth: insert (hard alloy teeth) three-cone bit and milling teeth (steel tooth) three-cone bit.
The tricone bit is one of the most widely used drilling bits, which has the characteristics of wide adjustment and high speed. The tricone bit consists of two dozen parts, including cutting structure, bearing structure, locking device, oil storage sealing device and nozzle device.
The cone bit has the effect of shock, crushing and shear crushing formation rock during rotation, so the cone bit can adapt to soft, medium and hard layers. Especially, the drilling speed of the cone bit is greatly improved after the emergence of the jet cone bit and the long nozzle cone bit, which is a major revolution in the development of the roller bit.

Functions and features:
1. The service life of the bit is longer than that of cemented carbide and 4-5 times of that of ordinary diamond bit;
2. High drilling efficiency: the diamond outcrop is large (almost all the composite polycrystalline layers are exposed), and the bit can always keep sharp, thus greatly improving the footage speed;
3. It can drill with low pressure and low rotation speed: the bit breaks the rock by scraping and shearing, and its WOB only needs about 1 / 3 of that of the impregnated diamond bit of the same diameter;
4. Good diameter protection effect: diamond polycrystalline can be inlaid inside and outside of the drill bit of our factory, which has strong wear resistance and good diameter maintenance performance, It has been proved that the bit is suitable for drilling soft and medium hard strata (with drillability below grade 9) such as carbonate rock, limestone, Cretaceous, clay rock, siltstone, sandstone and so on. Compared with the general bit, especially in the 6-9 rock stratum, the effect is particularly remarkable;
6. Because of its high penetration rate and long service life, the number of trips and trips is less, the drilling cost is greatly reduced, and the performance price ratio is superior.
