API Tricone Roller Cone Drill Bit 17 1/2" 444.5mm IADC535 /537g High Performance Tricone Drilling Bits

High-Performance tricone drill bits integrate advanced materials and precision design to maximize efficiency and durability. Featuring reinforced tungsten carbide inserts or diamond-enhanced teeth,

these bits deliver superior wear resistance in abrasive formations such as quartzite, basalt, and compacted sandstone. Their optimized cone geometry and sealed, lubricated bearing systems ensure smooth rotation under high axial loads, minimizing downtime in deep-well oil/gas exploration or geothermal projects. Enhanced heat dissipation channels and alloy steel components provide exceptional thermal stability in environments exceeding 300°C. Customizable with directional drilling compatibility and real-time wear monitoring options, these bits achieve up to 30% faster penetration rates compared to conventional models while maintaining borehole precision. Ideal for ultra-deep reservoirs, hard-rock mining, and complex stratigraphy, they redefine reliability through reduced

tripping frequency and extended service life in the most demanding operational scenarios.

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.
