LST1+ Water Well Drill

Providing greater speed and power compared to the LST1, the LST1+ features a 3,000-psi hydraulic system for a rotary speed of 95 rpm at 10 gpm. The LST1+ is capable of drilling a 6-inch borehole to a depth of 300 feet. The drill’s robust hydraulic system generates up to 5,000 pounds of pull/push-back force for efficient drilling in rugged terrain. The convenient bypass flow system allows precise control and adjustment to achieve desired push-down force, while a three-way ball valve enables the operator to quickly bypass mudflow when adding pipe. The drill’s swivel base design swings the rotary aside for quick, easy access to the borehole.
