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:
