Horizontal Directional Drills (HDD)

TERRA’s HDD drill rigs are designed to pack serious performance into a compact, jobsite-friendly package—covering a broad spread of directional drills (6–20 tonnes) with all-terrain options and dual-rod rock-drilling variants for tougher ground conditions, plus pit-launched machines for tighter launch locations. On the S-Series rigs, the hydraulic system is set up so you can apply strong pullback and torque simultaneously under full load, helping you maintain steady production in mixed or demanding geology. Add in an operator-focused cab and control layout, plus service-friendly access to key components, and you get a rig that’s built to stay productive and straightforward to live with on site—day after day.
