The LHD series is the premier drill in this class, offering the most capacity in a road-legal unit that does not require permits to move.
The unique crowd design allows the mast, winch, Kelly, and rotary gearbox to feed the drill tool simultaneously, making it easier, safer, and more efficient, too. The LHD is available in several different models, including a “Short Mast” road-legal truck-mounted unit, a crawler-mounted unit, and now, this special configuration with PowerBully.
This versatile unit has the increased capacity and ability to drill larger diameter holes in even the toughest soil conditions.
Whether you prefer square or round Kelly bars, our multiple mast-height configurations on the LHD will give you the confidence you need for every job.

“In most construction projects, jobs are performed under fixed-price estimates, so productivity is what makes your money. Spiradrill rigs have provided me with way more productivity than any other hole digger we’ve used”
