General Introduction:

Tricone bits are very widely applied bits in current industries like, mining, water-well drilling, oil-well drilling, and thermal drilling and so on. Besides AM and AX series bit, other series tricone bits are also what Superdrill people have been dealing with for very long time. Especially for small diameter ones, (diameter not up to 8 1/2), weve step into the position to ensure very good cost-effectiveness, including Steel Tooth (also referred to as milled tooth) bits and Tungsten Carbide Insert (TCI) bits.

TCI bits are much more durable than Steel Tooth ones, but carry a higher cost to manufacture. Both these two groups of Tricone Bits are available with

Open Bearing or Sealed Bearing;

Roller Bearing or Friction Bearing (Journal Bearing);

Gage Protected or Non-Gage Protected, etc.;

Bit IADC Code: ranging from 1 to 8 series, such as 111, 131, 124, 532, 642, 722, 832, 114, 125, 515, 545, 645, 735, 845, 126 117, 137, 437, 517, 537, 637, etc.;

Bit Size: cover size from 3 3/8”(85.7mm) to 26(660.4mm);

Application: water well drilling, oil well and thermal drilling.
