Core barrels H-WL – Wireline core drilling

The H-WL wireline core barrel from Technidrill represents an essential tool for mining exploration drilling. Designed for high-efficiency core extraction, this model includes Technidrill’s advanced EZY-LATCH™ system. It ensures smooth operation and maximum safety during core retrieval. Available in 5 ft and 10 ft lengths, the H-WL core barrels use EUTALOY technology. It combines robust construction with a long service life in both standard and high-stress drilling environments.

Each H-WL barrel includes a complete knuckle head assembly, inner and outer tubes, locking couplings, and diamond reaming shells as accessories. It also offers compatibility with a wide range of coring bits. The modular design supports quick maintenance and part replacement, reducing downtime in the field. Optional features like Triplex configurations (H-WL 3) with split tubes, stabilized systems, non-coring kits, and underground variants (H-WL U) provide flexibility for different geological settings—from surface coring to subsurface exploration.

Technidrill’s H-WL barrels are compatible with diamond or carbide locking couplings, reaming shells of 10” or 18”, and specialized FULL HOLE connections. Operators can choose between slotted, fluted, or diamond-plated core lifters, depending on the hardness and abrasiveness of the formation. This adaptability makes the H-WL a trusted solution for both mining and geotechnical drilling projects.

The complete range of wireline core barrels by Technidrill

Technidrill’s wireline core barrel range offers a complete suite of tools engineered for performance and durability across drilling environments. The series includes models covering the full spectrum of borehole diameters and geological conditions such as:

  • B-WL,
  • BTW,
  • N-WL,
  • H-WL,
  • P/HWT,
  • GEOTECH S
  • and TCS 146.

Each series is designed to optimize recovery, safety, and operational speed. The EZY-LATCH™ head system, featured across the wireline product line, simplifies handling and ensures consistent latching under pressure. These barrels are compatible with Technidrill’s wireline drill rods. These tools are available in standard, thin wall, and heavy-duty configurations, providing complete drilling solutions from the surface to deep core retrieval operations.

Beyond core barrels, Technidrill offers a comprehensive selection of impregnated and coring bits, reaming shells, and stabilizers. Together, these components form an integrated system that maximizes drilling precision and core quality. Whether in mineral exploration or geological surveys, Technidrill’s wireline tools are recognized for its reliability and long-term value.
