NTW thin wall wireline rods for efficient core drilling

NTW thin wall wireline rods are designed for professionals who require accuracy, reliability, and efficiency on demanding drilling sites. At Technidrill, these rods are manufactured under strict quality controls to ensure consistent performance throughout their service life.

Thin wall wireline rods are widely used in mineral exploration and geotechnical drilling, where core recovery and penetration rates are critical. The NTW configuration offers an excellent balance between strength and reduced wall thickness, allowing smoother drilling operations with lower energy consumption.

Key characteristics of NTW wireline rods

NTW wireline rods are engineered with precise dimensional tolerances. Their thin wall design reduces overall weight while maintaining the mechanical resistance required for deep drilling applications.

The NTW rods feature a constant outer diameter of 73 mm and an inner diameter of 64.3 mm. This configuration supports stable circulation and efficient core extraction during wireline drilling operations.

Main technical characteristics include:

• Outer diameter: 73 mm (2”7/8)
• Inner diameter: 64.3 mm (2”1/2)
• Available usable lengths: 1,000 mm, 1,500 mm, and 3,000 mm
• Also available in imperial lengths of 5 ft and 10 ft
• Compatible NTW saver sub recommended at the top of the drill string

These thin wall wireline rods are supplied with precise threading to ensure secure connections and reduced wear during repeated make-and-break cycles.

Advantages of wireline rods in drilling operations

Using wireline rods improves drilling efficiency by lowering the total string weight. This reduction helps limit rig stress and enhances handling safety on site.

The NTW system allows faster penetration rates, particularly in soft to medium formations. Operators benefit from improved core recovery and reduced downtime during rod handling.

Additional advantages include:

• Optimised weight for easier transport and handling
• Consistent performance in wireline core drilling
• Compatibility with standard NTW tooling
• Controlled manufacturing and regular quality inspections

Technidrill recommends using an NTW saver sub to protect the rod connections and extend the overall lifespan of the drill string.

Packaging and logistics

NTW rods are supplied in standardised bundles to simplify transport and storage. Each bundle contains 19 rods, securely packed for international shipping.

For large projects, a full 20-foot container can hold up to 684 rods in 3,000 mm lengths, ensuring efficient logistics planning for drilling contractors.
