As a premier Iranian supplier of drilling bits export from Iran, we proudly offer the IADC 537 TCI tricone bit from Tehran Rock Drilling Industries (TRDI), a pioneer in rock drilling tools since 1995. Engineered for demanding onshore and offshore operations, this bit delivers superior penetration rates and durability in medium-hard formations, making it a go-to choice for global oil & gas explorers, mining firms, and well drillers. With Iran’s advanced CNC manufacturing and rigorous quality controls, our Iranian tricone drilling bits comply with API 7-1 and ISO 9001 standards—ensuring seamless integration into your rigs while slashing costs by up to 25% compared to imports.

• Key Specifications:
• Size & Gauge: 8 1/2 inches (215.9 mm) diameter; API regular pin connection (2 3/8″ REG).
• IADC Code: 537 (medium formation, tungsten carbide inserts for enhanced wear resistance).
• Bearing System: Sealed journal bearing with O-ring seal; friction-reduced for high-temperature operations up to 250°F.
• Cutters: 46-52 TCI inserts (chisel-shaped for aggressive cutting); row distribution optimized for balanced load.
• Weight & Dimensions: 25 kg; body made from high-strength alloy steel (AISI 9310 equivalent).
• ROP & Durability: Rated for 50-100 hours in medium-hard rock; max WOB 20,000 lbs, RPM 50-120.

Features & Benefits: Advanced insert geometry minimizes vibration and bit balling; elastomeric seals prevent contamination for longer runs; computer-simulated designs boost ROP by 15-20%. Eco-conscious production uses recyclable alloys, supporting sustainable drilling worldwide.

Applications: Perfect for vertical/horizontal drilling in sandstone, dolomite, limestone, and shale. Suited for oilfield exploration, geothermal wells, mining shafts, and HDD projects across the Middle East, Africa, and Central Asia.

Export-Ready from Iran: TRDI’s bits are battle-tested in major Iranian fields (e.g., Ahvaz, South Pars) and exported to 20+ countries with full traceability, COA, and customs support.
