Non-Sealed Roller Bearing Tri-cone Bits
◆Cutting Structure
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
◆IADC
vary from 114--637 applicable for the hole drilling in the upper section with good drill ability.
