In the high-stakes industry of deep hole mineral exploration, structural integrity and tools reliability are paramount. Geotechnical and mining teams constantly face the challenge of drilling deeper while combatting severe mechanical stresses, abrasive geological formations, and costly operational delays. To address these extreme environments, the release of the new Zebra wireline rods introduces an unmatched standard of durability and engineering precision to modern wireline core drilling operations.
Induction heat treatment for unparalleled longevity of your wireline rods
The core innovation behind Zebra’s new wireline coring rods lies in its state-of-the-art induction heat treatment unit. We are one of fewer than five specialized heat treatment machines of this caliber in Europe. This technology is fully integrated directly into the production process. Consequently, this seamless integration drastically boosts manufacturing responsiveness, allowing for significantly shorter lead times and unparalleled quality control.
The localized induction treatment process follows a rigorous, engineered sequence:
- The tube ends undergo heating.
- The heated ends are immediately dipped and quenched in oil.
- Controlled tempering is executed on the rod ends over approximately 250 mm.
- Afterward, the process finishes with a uniform cooling cycle.
As a result, this localized treatment specifically increases the material hardness to 32 – 38 HRC at the critical connection zones. We transform these high-wear sections into high-strength alloy steel drill rods. So Zebra reinforces structural durability exactly where it is needed most: at the tapered thread drill rods joint and the jaw-grip areas.
Performance benefits: engineered for the field
Maximize Core Recovery Rate
In complex drilling conditions, any deflection or vibration can compromise core sample integrity. Zebra rods achieve a perfect balance between stiffness and flexibility through a rigorous selection of raw materials. This balance ensures performance and reliability in complex drilling.
Reduce Drilling Downtime with Zebra range
Pulling a damaged string out of a deep hole wastes valuable operational hours. Crews can safely run longer cycles and drastically reduce drilling downtime. Why? Thanks to the reinforced durability of the treated threads and an innovative single wear groove option to optimize the lifespan of drill rods.
Tailored specifications of wireline rods for complex projects
To support diverse exploration programs and adapt to standard global setups for diamond core drill rods, the new Zebra wireline rods are available in standard industry diameters and versatile lengths to fit drill rigs:
