IADC code explained


The first digit represents the hardness of rock formation the drilling tool buttons are suited for

Every drill bit is designed for a certain type of rock formation, ranked according to hardness.
The tool is assigned a number between 1 and 8 indicating the type of rock the teeth or buttons of a drilling tool are designed for:

1~3: Indicate a steel tooth.

"1" is engineered for soft rock formations , "2" for medium formations , and "3" for hard formations.

4 ~ 8: Indicates a tungsten carbide insert (TCI ).
"4" is designated for the softer formations , with 8 representing the hardest formations


The second digit represents further rock formation information
Regardless of tooth type, the second digit takes into account all factors of the bit and ranks the rock formations the drilling tool is best suited for on a scale from 1 to 4. 1 represents soft formations going up to 4 representing the hardest formations.


The third digit represents the bearing type of the drilling tool.

The fourth digit is a letter indicating the special properties of the drilling tool.
In addition to the buttons, intended rock formations, and bearings used, tricone bits can have numerous other special properties:


A – Air Application

B – Special Bearing

C – Center Jetted

D – Deviation Control

E – Extended Jets

G – Extra Gauge or Body protection

H – Horizontal/Steering

J – Jet Deflection

L – Lug Pads

M – Motor Application

S – Standard Steel Tooth

T – Two Cone

W – Enhanced Cutting Structure

X – Chisel Inserts
