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.
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:
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.
Behind every Technidrill product is a dedicated engineering and design office focused on innovation and customization. The company’s in-house R&D team collaborates directly with clients to design tailor-made coring systems, adapting dimensions, materials, and mechanisms to meet specific field requirements.
Technidrill’s approach combines decades of drilling experience with advanced 3D modeling and prototyping, ensuring each core barrel system meets international quality standards and operational constraints. This capacity for custom or special project development allows Technidrill to serve clients across mining, geotechnical, and research sectors with unique, precision-built tools.
From feasibility studies to full-scale production, every custom wireline solution is engineered for optimal performance and longevity — reflecting Technidrill’s commitment to reliability and precision in core drilling technology.
Technidrill’s H-WL wireline core barrel stands out as a robust, high-performing tool engineered for accuracy, flexibility, and endurance. Combined with the brand’s full range of wireline systems and its in-house design expertise, Technidrill continues to push the limits of core sampling technology for professionals seeking efficiency and precision in every drilling operation.
