DeepRock Hydra-Drill for Heavy Duty Applications

The industry standard for portable drill rigs

The HD77 is our largest portable drill rig.  Every feature that experienced drillers look for in a compact, portable rig has been incorporated into the HD77.   The power source is a world-standard Honda 5.5 HP OHV engine with plenty of low-end torque coupled to a heavy-duty General 330 gearbox.

Designed for finished wells up to 4" in diameter and able to reach to depths of 300', the HD77 represents an extraordinary value in a very rugged,  portable drill rig.
