    Product details



    Core drill Fan type PDC drill bit diamond drill bit

    Suitable for sandstone rock formations, sharp bit, fast drilling speed and high efficiency.



    Geological exploration pdc core drill bit composite broken rock advantages:

    The rock breaking principle of diamond bit is the same as that of cemented carbide drilling, This is because when the hard alloy is initially drilled, the edge part is very sharp and the efficiency is very high. However, because the hard alloy is not wear-resistant, the edge part is quickly ground flat or the force is uneven and the edge collapses. At this time, the hard alloy is not shearing rock, but crushing rock. At this time, it is often due to insufficient WOB. The efficiency also drops rapidly and the service life of the drill bit is very low. However, because the wear resistance of diamond at the edge is much higher than that of hard alloy, the diamond drill bit is very slow in drilling and wear in the formation, and can always take rock in the form of shear, with little change in efficiency and long service life.
