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.
