3 7/8'' IADC537 TCI Tricone Bit Sealed Bearing for Soft to Medium Formation

The 3 7/8" IADC537 TCI Tricone Rock Bit is a tungsten carbide insert tricone roller bit manufactured in compliance with API Spec 7-1 and IADC standards. Model IADC537 is engineered for soft to medium formations such as shale, sandstone, and medium limestone.

Equipped with a sealed journal bearing and hard tungsten carbide inserts, this bit delivers a stable penetration rate, excellent wear resistance, and long service life. It is widely used in water well drilling, geological exploration, mining, and horizontal directional drilling (HDD) projects.

This versatile drilling bit is suitable for a wide range of drilling operations, including:

• Water well drilling
• Geothermal well drilling
• Mining drilling
• Geological survey
• Horizontal directional drilling (HDD)

Custom thread connections and gauge protection options are available upon request.

• Tungsten Carbide Cutters (TCI): High-toughness tungsten carbide cutters with a tooth surface hardness exceeding HRC85 and compressive strength suitable for formations of 15,000–25,000 psi, extending drill bit life by 40% compared to steel cutters.
• Cut Layout: Staggered cutter placement reduces vibration, while lateral nozzles (3–4) enhance cutting efficiency and reduce repetitive cutting losses.

• Double Thrust Bearing: Carbide journals with a silver-plated anti-friction coating offer temperature resistance up to 200°C and a speed range of 50–120 rpm.
• Rubber Seals + Elastic Compensation: Bimetallic seals and O-rings prevent mud intrusion, while a grease compensation system ensures long-term bearing lubrication.

• Gauge Protection: A tungsten carbide block is embedded in the tail of the cutter to prevent wear on the wellbore wall and maintain a stable borehole diameter.
• Modular Design: Supports adjustment of the number of nozzles (3–6) and spray angle, suitable for water-based or oil-based mud systems.

• Packing: Wooden box
• Delivery: Normally 5–7 days after down payment
• Shipping Method: By express, by air, or by sea
