The N-WL drill rod type manufactured by Technidrill is designed to meet the demanding requirements of mining exploration and wireline core drilling. Each rod delivers precise torque transmission, excellent alignment, and high resistance to wear, ensuring maximum performance even in deep or abrasive formations.

Built with premium-grade steel, these rods undergo rigorous quality control to maintain dimensional accuracy and thread integrity. The result is a drill rod that combines durability, reliability, and smooth make-up—key factors for consistent productivity on your exploration site.

Available in 1000 mm, 1500 mm, 3000 mm, 5 ft, and 10 ft lengths, the N-WL rods can be configured to fit a variety of drilling setups. To adapt to different ground conditions, Technidrill offers optional steel treatments, improving tensile strength for demanding environments or increasing flexibility when the geology requires greater adaptability.

Designed for Mining Exploration Efficiency

When it comes to mining exploration, core recovery and drilling efficiency are everything. N-WL drill rods play a central role in wireline coring systems—transmitting torque from the surface to the bit while ensuring stable, safe operation.

Technidrill’s manufacturing precision guarantees smooth threading and perfect alignment, which minimizes energy loss, vibration, and fatigue across the entire drill string. This engineering precision directly translates to higher penetration rates, cleaner core samples, and reduced maintenance time on site.

Every Technidrill N-WL rod is tested to perform under pressure—literally. Whether you’re drilling hard rock, fractured zones, or deep mineral targets, these rods provide the consistency and reliability needed for accurate geological exploration.
