Product Description

Product Description

 

IADC Codes - Tricone Rock Bits

IADC Codes are designed to make it easier for drillers to describe what kind of rock bit they are looking for to the supplier. 

Such as 12 1/4" IADC617, The first three digits classify the bit according to the formation it is designed to drill and the bearing/seal design used.

Bit Type and Hardness of Formation to be Drilled

First Digit:

1, 2, and 3 steel tooth bits (from softest to hardest).

4, 5, 6, 7, and 8 tungsten carbide insert bits (from softest to hardest).

Second Digit:

from softest (1) to hardest (9).

Third Digit 

Stand for bit feature as follows: 

Open Bearing 

Open Bearing, Air Cooled 

Open Bearing with Gauge Protection 

Sealed Roller Bearing 

Sealed Roller Bearing wih Gauge Protection 

Sealed Journal Roller Bearing 

Sealed Journal Roller Bearing with Gauge Protection.

Tricone bits included 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 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
