Working theory of TCI tricone bit
The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.
Tricone bit is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air.

What is Hard Rock Drill Bits
 
 
All bits the above are manufactured according to strict standards, set forth by the American Petroleum Institute (API).
And classified according to characteristics set forth by the International Association of Drilling Contractors (IADC).

Hard Rock Drill Bit is cut rock by Tungsten Carbide teeth projecting from rolling cutters, which rotate on the drill-bit bearings. Inturn, the drill bit rotates at a high rate, and presses against the bottom hole with a high axial force. The teeth of the rolling cutters roll over the bottom hole and, owing to the large stresses that develop in the area of contact between the teeth and the rock, cut the rock by crushing and chipping. As the hardness of therock increases, the rotation rate decreases and the axial force increases. Destroyed at the mine the rock is removed to the surface by air compressor, mud pump, or a combination of these methods.All bits the above are manufactured according to strict standards, set forth by the American Petroleum Institute (API). And classified according to characteristics set forth by the International Association of Drilling Contractors (IADC).

Advantage:

1. Optimized cutting structure and bearing geometry to distribute load .
2. More uniformly distributed load over bearings.
3. Smoother bit performance .
4. Sustained penetration rate over longer periods of time .
5. Reduced risk of bearing failure .
6. Streamlined lug manages.
7. larger drill cuttings.
8. Higher penetration rate Less regrinding of cuttings to smaller pieces.
9. Less bit wear.
10. Full body armor minimizes wear on bit body and shirttail.
