Product Description
Product advantage
One of the most used in oil drilling and geological drilling or tricone bit. Tricone bit in shock when it is rotating, crushing and shearing crushing rock stratum, so bit can adapt to all kinds of soft, medium and hard formation. Especially in jet cone bit and rock bit long nozzle, rock bit drilling speed is greatly increased, is a significant revolution in the history of the development of roller bit. Bit by teeth type can be divided into gear milling (steel tooth bit, insert (install) of hard alloy tooth on the cone with roller bit
Bit is one of the most widely used drilling bit. Bit cutting teeth while working alternate contact bottom hole, broken rock torque is small, the cutting tooth contact with the bottom area is small, the pressure is high, easy to eat into the formation; Work blade length, thus less wear and tear. Bit can adapt to various formation from soft to hard.
