64 Bar R25 Drill Rod 3660mm

Engineered for Extreme Conditions: 64 Bar Pressure-Rated R25 Drill Rod, 3660mm Length

High-strength R25 drill rod (3660mm) rated for 64 bar operating pressure, precision-forged from ISO9001-certified alloy steel. Features a robust hexagonal body, friction-welded MF heads, and optimized heat treatment for exceptional fatigue resistance and wear life in hard rock drilling.

Available with T38, R32 or R38 thread configurations, fully compatible with standard rock drilling rigs. Designed for demanding applications including tunnel boring, underground mining, and quarry excavation — where reliability, torque transfer, and dimensional accuracy are non-negotiable.

Key Advantages

  • 64 bar pressure rating — validated for high-intensity hard rock drilling cycles
  • ISO9001-certified alloy steel with proprietary heat treatment for extended service life
  • Hexagonal body design ensures superior torsional rigidity and anti-rotation stability
  • Friction-welded MF heads with internal thread protection — minimizes head separation and thread damage
  • Precision CNC-machined threads (T38/R32/R38) meeting tight tolerance standards (±0.05mm)
  • Fully traceable batch documentation and 100% dimensional inspection prior to shipment

Applications

  • Tunnel boring machine (TBM) extension and feed systems
  • Underground hard rock mining (stoping, development, raise boring)
  • Quarry drilling for granite, basalt, and quartzite extraction
  • Foundation piling and geotechnical exploration in abrasive strata
  • Drill-and-blast operations requiring high-torque energy transfer
  • Retrofit upgrades for aging R25-compatible drill rigs

FAQ

Is this R25 drill rod compatible with Atlas Copco and Sandvik rigs?
Yes — the R25 thread specification complies with ISO 2173:2002 and is fully interoperable with Atlas Copco COP, Boomer, and Sandvik DR series rigs when matched with corresponding R25 couplings.
Can I order custom lengths or non-standard threads?
Yes. We support custom lengths (600–6400 mm) and thread variants including T45, T51, GT60, and proprietary configurations — lead time extends by 5–7 working days.
What is the typical delivery time for 1–5 pcs?
Standard delivery is 20 working days after confirmed order and T/T deposit; expedited production (12–15 days) is available upon request and subject to capacity.
How is quality verified before shipment?
Each rod undergoes 100% dimensional inspection, hardness testing (HRC 38–42), ultrasonic flaw detection, and thread engagement validation. Full EN 10204 3.1 certification provided.
