5 3/8" Sealed Bearing Hard Rock Tricone Drill Bit IADC 537

Size: 5 3/8 inches (about 136.5mm), IADC537, designed for hard to extremely hard abrasive formations (such as dolomite, quartzite, siltstone)

Efficient Drilling: The ROP (Rate of Penetration) can reach 8-12 meters per hour in mudstone-sandstone interbeds, a 25% improvement over similar products.
Cost Control: The bearing life reaches 200-300 hours, reducing tripping times and lowering overall drilling costs by 15%-20%.

Cutting Structure
Tooth Type:
Tungsten Carbide (TCI) inserts with weld overlay technology for enhanced wear resistance, suitable for high WOB and high-speed rotation.
Specially designed tapered spherical inserts for efficient hard rock crushing.
Gage Guard Design: Tip and back gauge guards ensure a regular wellbore and extend bit life.

Bearing and Sealing System
Bearing Structure:
High-precision plain bearings with dual thrust faces and silver-plated anti-friction alloy for enhanced anti-seizure resistance.
Ball-locking cones enhance drilling stability.
Seal Technology:
Rubber seals (HNBR O-rings) or metal seals, resistant to high temperatures and pressures. Compensation system maintains lubrication reliability.

Performance Features
Applicable Formations:Hard to extremely hard and abrasive formations, such as oil, gas, geothermal, and water wells.
Speed ​​and WOB: Suitable for 50-120 rpm, capable of withstanding high WOB operations.
Nozzle Design: Three standard nozzles optimize mud circulation and cuttings removal.

Packing: wooden box.
Delivery: Normally 10 days after down payment.
Shipping method: by express, by air or by sea
