3. Interpretation of IADC CODE

 
First Digit (1~8): 
-1, 2, and 3 designate STEEL TOOTH BITS with 1 for soft, 2 for medium and 3 for hard formations. 
-4, 5, 6, 7 and 8 designate TUNGSTEN CARBIDE INSERT BITS for varying formation hardness with 4 being the softest and 8 the hardest.
Second Digit (1~4):
-1, 2, 3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest.
Third Digit (1~7):
This digit will classify the bit according to different bearing/seal type and special gauge wear protection as follows:
-1. Standard open bearing roller bit. 
-2. Standard open bearing roller bit, air-cooled. 
-3. Standard open bearing roller bit with gauge protection which is defined as carbide inserts in the heel of the cone. 
-4. Sealed roller bearing bit. 
-5. Sealed roller bearing bit with gauge protection on heel of cones. 
-6. Journal sealed bearing bit. -7. Journal sealed bearing bit with gauge protection on heel of cones.
Feature Code:
The following codes are used in the fourth digit position to indicate additional features:
A: Air Application 
R: Reinforced Welds 
C: Center Jet 
S: Standard Steel Tooth 
D: Deviation Control  
X: Chisel Insert  
E: Extended Jet  
Y: Conical Insert  
G: Extra Gage Protection  
Z: Other Insert Shape  
J: Jet Deflection 


4. Details of Tricone Bit
   1) Significantly improve the drilling speed, and reduce the drilling cycle.
   2) The wearing-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel  tooth bit. The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
  3) Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capacity and bearing life.
  4) Apply to soft, medium hard and hard formation.
