5 3/4 Inch 146mm JZ Tricone Rotary Drill Bits IADC617

During the operation of a three cone drill bit, the effect of drilling pressure also needs to be considered. Drilling pressure is the pressure applied to the drill bit through the drill pipe, which can help the drill bit better crush and break rocks. The size of drilling pressure needs to be adjusted reasonably based on the formation hardness and drilling depth to ensure the cutting efficiency of the drill bit and the safety of drilling.
