API newest kingdream IADC637 TCI tricone bit for hard rock/coal mining bit - HA637

1. Optimally designed bit profile for drilling soft to medium hard formations.

2. Cutting structure is force balanced, bit blade is asymmetrically designed, and spiral blade and spiral gage are also designed so that the load on bit is balanced that resulting better stability of the bit.

3. Multiple types of high performance PDC cutters are strategically arranged on the bit for improved service life of the bit.

4. Hydraulic system of the bit is optimized using CFD technology to enhance cleaning and cooling effects of the bit as well as the ability to effectively prevent bit from balling.

5. Erosion on bit surface is effectively prevented by utilizing hardfacing material of highly erosion resistant and applying advanced base metal enhancement technology.

6. Ports on bit are also optimally designed to prevent erosion of water courses inside the bit.

7. Up-reaming features are also designed to make the bit more suitable for various drilling processes.

IADC Codes make it easier for drillers to describe what kind of rock bit they are looking for to the supplier. Bit Brokers International follows the IADC bit classification system in which the first three digits classify the bit according to the formation it is designed to drill and the bearing/seal design used.

First Digit:

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, 2, 3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest.

Third Digit:

This digit will classify the bit according to bearing/seal type - see information on different bearing types - and special guage 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
6. Journal sealed bearing bit
7. Journal sealed bearing bit with gauge protection

Fourth Digit:

The following letter codes are used in the fourth digit position to indicate additional features:

1. 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
