Our drilling bits manufacture are based on the extensive research and development in the field of mining. All the Rock Drilling Bits using the finest raw materials available, including Premium Steel and Tungsten Carbide. We ensure that our worldwide clients have quick access to our service, manufacturing and marketing expertise. Our vision is to become the industry's performance leader in tools that withstand the toughest rock drilling demands. That's why our products exceed industry specifications for performance and safety. When you work with TianYing, we are committed to your productivity and efficiency.

All of our bits 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).

This Series Of Rock Roller Bits Can Apply For Drilling Hard To Very-Hard Formation.
Application : For use in abrasive consolidated formations with compressive strength above 400 Mpa such as taconite, quartzite and banded iron formations
Cutting structure: These bits are characterized by closely spaced conical or spherical inserts with medium to low projection. This configuration promotes good penetration rates in hard, consolidated and very abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve performance.

• Compression Strength: 60,000 – 100,000 psi
• Drilling Speeds: 50 – 90 rpm
• Jet Circulation: All sizes
• Weight on Bit (WOB): 4,000 – 7,500 lbs/in of bit diamete

What is Tricone Drill Bit ?

Roller Cone Bit - a drilling method that uses a roller bits. In roller-bit drilling, rock is cut by hard-alloy 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.


CUTTING SELECTION GUIDE

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.
