ENG offers heavy duty Steel tricone drill bits to meet your customized needs.
We have classified the bits based on their diameter (footprint), American Petroleum Industry number (API Number) and International Association of Drilling Contractor number (IADC number).
The IADC number further classifies the tricone bits based on the tooth material of construction, suitability for drilling into soft, medium or hard rock and bearing type used.
ENG manufactures tricone bits for all possible combinations of IADC numbers.
Tricone drill bits include Steel Teeth (or milled teeth) bits and Tungsten Carbide Insert (TCI) bits, TCI drilling bits are much more durable than Steel Teeth bits, but come with a higher cost to manufacture.
Both these two groups of Tricone Bits are available with
(1) Open Bearing or Sealed Bearing
(2) Roller Bearing or Friction Bearing (Journal Bearing)
(3) Gage Protected or Non-Gage Protected, etc.
