It is the first step to know the selection and operation of drilling bits ,then we can know what type of drill bit is our best choice. Rotary drilling bit is classified according to the design rolling cutter bits.Our tricone bits cover almost all IADC code.Fast drilling speed is our target.We try to make reliable bearing system and long working. Tricone bit have two types of different materials, one is mill tooth tricone bit, another is TCI tricone bit. Tungsten carbide insert cutter of high strength and toughness is used to increase the impact resistance of cutters and decrease the breakage rate.Widely use in oil exploration ,mining prospecting, water well drilling,subterranean heat, hydrology,etc.| Basical Specification | |

16" IADC537G is the most regular sizes and hot selling model tricone bits in the world. Drill bits are used in the oil and gas industry as a component which produces holes of almost circular cross-section in the earth’s crust for the extraction of crude oil and natural gas. It is majorly deployed in the rotary drilling method to produce the hole in the fields. There are various types of drill bits of different shapes and sizes. These are used by the industry to remove materials in order to create holes. China Far Eastern provides tricone roller bits for oil well drilling contractors and government tenders, optimal solutions could be designed according to detailed geological information.With fast delivery time and warm after-sale service,Choose the correct model is important during the drilling project. Far Eastern Drilling will keep fast delivery time and after-sale-service.W have exported more 35 countires.We have many expericence to produce the drill bits .Our engineer have advanced drilling solutions for different drilling project. The application icnluding gas oil well drilling, natural gas drilling, geological exploration drilling, birectional boring drilling, water well drillig.
