milled tooth rock bit parameters:
Tungsten Carbide Inserts: Various type high quality tungsten carbide inserts can be equipped on the bits, professional and scientific selection of the inserts as per the different application and drilling process to achieve high efficient drilling production.
Steel Tooth: Premium tungsten carbide hard facing on the surface, greatly enhance the wear resistance of the tooth.
Bearing Structure
Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling;
Balls lock the cone which reduces the probability of cone dropping to minimum
Seals and Lubrication
The advanced metal seals improve the reliability and stability of the bearing sealing. Pressure difference type compensating system assures a good greasing lubrication function.
