Tricone bits are used in a wide range of applications, including:
Water Well Drilling: Tricone bits are also used for drilling water wells, particularly in areas with hard rock formations that require durable and efficient drilling tools.
Mining and Quarrying: In the mining and quarrying industries, tricone bits are used for drilling blast holes and exploration wells in hard rock formations.
Oil and Gas Drilling: Tricone bits are commonly used in the oil and gas industry for drilling through various formations, from soft sedimentary rocks to hard igneous rocks.
Geothermal Drilling: Tricone bits are used in geothermal drilling projects to access hot rock formations and extract geothermal energy.

Using a new formula of tungsten carbide inserts and insertion techniques, the mechanical properties of the cutting teeth are reinforced for better cutting performance.
The bearing structure of a tricone bit is critical for ensuring the bit's durability and high speed operation. It includes:
Hardfaced Head Bearing Surface: This provides a wear-resistant surface that can withstand the high pressures and friction encountered during drilling.
High Precision Journal Bearing: With two thrust faces, this design allows for precise rotation and load distribution.
Ball Locked Cone: This secures the cone to the bearing pin, ensuring stability during drilling.
Cone Bearing: Inlaid with a friction-reducing alloy and then silver-plated, this enhances the bearing's resistance to abrasion and seizure, makes it suitable for high rotary speeds.
The gauge structure is designed to protect and maintain the borehole size
