Seamless interchangeability across the range keeps crews productive and minimizes downtime on site.
Built for deep projects
Engineered to withstand the axial loads, torque, and vibration of deep wireline drilling, the H-WL mining drill rod maintains alignment under stress, preserving borehole quality and improving run efficiency. Its geometry and thread integrity help reduce coupling wear and extend service intervals—key for remote or long campaigns.
Mining exploration drilling
In mining exploration, where core quality drives resource modeling and investment decisions, the H-WL mining drill rod delivers. High torsional capacity supports aggressive bit programs in hard, fractured lithologies; verified concentricity protects against core jamming and deviation; and precise threads enable quick rod handling for faster trip times. Whether you’re delineating ore bodies, confirming grade continuity, or expanding targets at depth, H-WL rods help increase core recovery, data reliability, and overall meter-per-shift performance.
Quality that holds up in the field
Technidrill applies rigorous quality assurance at every stage—dimensional verification, hardness testing, and visual weld/finish inspection—to ensure consistent performance and long service life. Manufactured to international drilling standards, H-WL rods combine proven French engineering with field-tested reliability for geotechnical, environmental, and—above all—mining exploration programs.
If your priority is deep, accurate, and efficient wireline coring, the Technidrill H-WL mining drill rod offers the strength, precision, and compatibility you need—shift after shift.
Technidrill supplies end-to-end mining exploration drilling tools, from reverse circulation (RC) systems for fast, low-contamination sampling to wireline coring solutions (A-WL, B-WL, N-WL, H-WL) that maximize recovery at depth, plus conventional core barrels for versatile setups in mixed formations. Engineered and made in France, these tools deliver durability, tight concentricity, and reliable sample integrity across demanding terrains.
