3 7-8" IADC537 TCI Tricone Rock Bit for Hard Shale Drilling‌

3 7-8 " IADC537 TCI Tricone Rock Bit

3 7/8" IADC537 TCI Tricone Rock Bit
This is a tungsten carbide insert tricone roller bit complying with API Spec 7-1 and IADC standard. Model IADC537 is designed for soft to medium formations such as shale, sandstone and medium limestone. Equipped with sealed journal bearing and hard tungsten carbide inserts, it delivers stable penetration rate, good wear resistance and long service life. Widely used for water well drilling, geological exploration, mining and HDD projects.

It is a versatile drilling bit for water well, geothermal well, mining drilling, geological survey and horizontal directional drilling (HDD). Custom thread connections and gauge protection options are available on request.

1. Optimized Cutting Structure
Tungsten Carbide Cutters (TCI): Utilizes 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, and lateral nozzles (3-4) enhance cutting efficiency and reduce repetitive cutting losses.

2. Bearing and Sealing System

Double Thrust Bearing: Carbide journals with a silver-plated anti-friction coating offer a temperature resistance of 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.

3. Enhanced Adaptability
Gage 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
