Tricone Drill Bit Metal Sealed Roller Bit High Performance Tricone Bit for Geothermal Drilling

Known for their adaptability to changing ground conditions, roller cone bits enhance drilling efficiency, reduce operational time, and lower costs across these critical sectors. Their design—featuring rotating cones with hardened teeth or carbide inserts—ensures consistent performance even in abrasive and challenging environments.

Cutting Structure:
The wear-resistance of the teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for the steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

Gauge Structure
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hard facing on the shirttail increases gauge holding capacity and bearing life.

Bearing Structure
High precision journal bearing with two thrust faces,Balls lock the cone.Hard faced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure of the bearing are improved.and suitable for highrotary speed.

Oil and Gas Exploration:
Roller cone bits are extensively used in drilling petroleum and natural gas wells. They excel in crushing and fracturing diverse rock types—from soft shale and sandstone to hard limestone and dolomite—enabling efficient wellbore creation for extraction and production.

Mining and Mineral Exploration:
These bits facilitate core sampling and blast hole drilling in mining operations. They are ideal for excavating mineral deposits, coal seams, and ore bodies, providing precise cutting performance in both surface and underground mining environments.

Geotechnical and Water Well Drilling:
In geotechnical engineering and hydrogeology, roller cone bits help construct water wells, monitoring wells, and foundation boreholes. Their ability to handle unconsolidated sediments, clay, and mixed rock layers ensures reliable performance in aquifer exploration and civil engineering projects.

Products Description

Notes for the use of roller cone bits:
1 .Before the drill bit is down, it is necessary to confirm that the bottom of the well is clean, free of grit, and no metal falling.
2. Check if the thread connection screw of the roller cone bit is intact and the nozzle is installed properly.
3. Run in hole needs to be stable, avoid stress and prevent drilling.
4. The last joint needs a large displacement to start the rotary table and keep reaming to bottom of the well., fully wash the well to prevent the debris from clogging the nozzle.
5. The shape of the bottom hole should be lightly pressed and slowly turned into contact with the bottom of the well, smalldrilling pressure, low speed, large displacement, small torque, and the speed is 40~60 rev / min, at least 30 minutes.
6. Determine the weight on bit and speed in combination with the actual conditions of the formation.
7. During drilling ahead, the operation should be smooth, drill feeding should be uniform, it is strictly forbidden to lift and release the drill sharply,drill string not well braked and drill string free fall.
8. If it is found that the drill bit stops making progress, the pump pressure increases and decreases obviously, the rate of penetration is suddenly decreased, and the torque is increased, lift the drill to check without delay.
