TCI Tricone Drilling Bit 17 1/2' 444.5mm High Drilling Efficiency Rock Drill Bit For Sale

TCI Tricone Drill Bit tricone bits are made from high-quality steel and carbide

materials for exceptional durability. They feature sealed bearing structures and

advanced vacuum oiling technology, ensuring longer bearing life and smoother

operation. Designed for performance in various rock formations, our tricone bits

deliver reliability and cost-effectiveness for your drilling needs.

Tricone drill bit features Tricone bits typically consist of cones, bearings, water passages,and nozzles. The core function is rock breakage through rotation and pressure.

The cones are studded with cutting teeth that alternately contact the well bottom, effectively

reducing wear and improving drilling efficiency. Tricone bits are classified by the number of

cones: single, double, triple, and multiple, with tricone bits being the most common due to

their good balance and high drilling efficiency. The bearing system is a crucial component of

the bit, typically using rolling or sliding bearings. The bearing inner race mates with the cone shaft,ensuring stability and wear resistance during high-speed rotation. The bit's locking system,

including ball locking and thrust bearings, secures the cones and withstands axial loads.

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.
