Drill Rods
High-strength drill rods engineered to transmit torque and drilling force reliably, forming the backbone of core drilling systems.
Role in the Core Drilling System
Drill rods are the primary load-bearing and torque-transmitting components in a core drilling system. Connected in series, they transfer rotational energy and feed force from the drilling rig to the downhole assembly.
Product Description
Wireline Drill Rods manufactured in AQ, BQ, NQ, HQ, and PQ sizes for mineral exploration and geotechnical drilling applications. Designed to ensure reliable torque transmission and dimensional compatibility within standard core drilling systems.
Standard Sizes, Lengths & Manufacturing
Drill rods are manufactured in standard sizes including AQ, BQ, NQ, HQ, and PQ, with standard lengths of 1.5 m and 3.0 m. Selection of size depends on drilling depth, formation conditions, and required core diameter.
All drill rods are manufactured from high-grade alloy steel with precision-machined threaded connections and controlled heat treatment processes to ensure strength, durability, and reliable field performance.

Selection Guidance
- Smaller sizes for shallow drilling and smaller core diameters
- Medium sizes for general exploration drilling
- Larger sizes for deeper drilling and unstable formations
Key Advantages
- Reliable torque transmission
- Secure threaded connections
- Manufactured to dimensional standards
- Suitable for continuous drilling operations
System Compatibility
Drill rods must be compatible with the selected core barrel, head assembly, and drilling rig. All drill rods supplied by Spenta Engineers are designed to integrate seamlessly with standard core drilling system components.
