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 for demanding hard rock drilling applications. Features a robust hexagonal body design, optional T38 / R32 / R38 threaded connections, and friction-welded MF heads with internal threading to prevent thread damage. Enhanced durability via advanced heat treatment and strict dimensional tolerances ensures optimal energy transfer, wear resistance, and service life in tunnel boring, underground mining, and quarrying operations.


MOQ: 1 PCS | Delivery: 20 workdays | Packaging: Export-grade wooden box | Payment: T/T

Key Advantages

  • 64 bar pressure rating — validated for high-intensity rock drilling in tunneling and mining
  • Hexagonal body design improves torque transmission and reduces slippage vs. round rods
  • Friction-welded MF heads with protected internal threads extend service life and prevent cross-threading
  • Forged from ISO9001-certified alloy steel with controlled heat treatment for superior fatigue resistance
  • Multiple thread options (T38, R32, R38) ensure seamless compatibility with leading rock drills
  • Tight tolerance manufacturing (±0.1mm) guarantees consistent coupling performance and minimal vibration

Applications

  • Tunnel boring machine (TBM) extension and face drilling
  • Underground hard rock mining (stoping, development, raise boring)
  • Quarrying and open-pit blast hole drilling in abrasive granite/basalt
  • Geotechnical investigation and deep foundation drilling
  • Drift and shaft excavation in high-stress ground conditions
  • Replacement rod for Atlas Copco, Sandvik, and Boart Longyear drill rigs

FAQ

Is this R25 drill rod compatible with Atlas Copco COP series drills?
Yes — the R32 and T38 thread variants are engineered to meet ISO 2147-1 specifications and are fully compatible with Atlas Copco COP 1238, COP 1838, and COP 2838 series drills.
Can I order custom lengths or non-standard threads?
Yes. We support custom lengths from 600–6400 mm and threads including R25, R32, R38, T38, T45, T51, and GT60 — all manufactured per your drawing or OEM spec.
What is the typical lead time for 1–5 pieces?
Standard lead time is 20 workdays after confirmed order and deposit; expedited production (12–15 days) available upon request and subject to capacity.
How is quality verified before shipment?
Each rod undergoes 100% dimensional inspection, thread gaging, hardness testing (HRC), and ultrasonic flaw detection. Full test reports and ISO9001 certificates accompany every shipment.
Does the 64 bar rating apply to continuous operation or peak pressure?
The 64 bar rating reflects maximum allowable working pressure under continuous duty at 25°C, validated per EN 13445-3 and internal fatigue cycling tests (>100,000 cycles).
Do you offer OEM branding and packaging?
Yes — we provide laser-engraved OEM logos, custom labeling, and branded wooden export crates with moisture barrier lining and fumigation certification (ISPM 15).
