Thrust / Pullback:
120,000 lbs of thrust and pullback force gives the AT120 unmatched power for long, challenging bores. Whether pushing through solid rock or pulling heavy product lines, the consistent linear force ensures productivity in all terrains.

Rotational Torque:
The inner pipe delivers up to 15,500 ft-lbs of torque, while the outer pipe provides up to 3,000 ft-lbs. This dual-pipe system isolates inner pipe rotation for better bit control in rock and high-resistance materials, minimizing vibration and increasing tooling longevity.

Spindle Speeds:
The inner pipe reaches spindle speeds of up to 200 rpm, while the outer pipe caps at 150 rpm. These high-speed capabilities allow for faster cutting and cleaner boreholes even in complex geology.

Drilling Fluid System:
Integrated fluid pump supports pressures up to 1,200 psi, ensuring consistent fluid flow for effective cuttings removal, bore stabilization, and cooling even on long-distance runs.

Engine & Powertrain:
Powered by a 280-hp Cummins® QSL9 Tier 4 Final diesel engine, the AT120 meets emissions standards while delivering high torque and fuel-efficient operation in demanding conditions.

Cab and Controls:
The cab features pressurized, climate-controlled comfort with ergonomic seating, full 360° visibility, and intuitive touchscreen displays. Operators benefit from advanced diagnostics, bore planning software, and real-time system monitoring.

Drill Pipe Compatibility:
Compatible with 15-ft drill pipe featuring a 3.5-inch inner pipe and 5.0-inch outer pipe. The extended length helps reduce makeup time and boosts overall jobsite productivity.

Onboard Fluid Capacity & Pumping:
Fluid system integrated with onboard mud pumps minimizes external equipment needs. This results in faster setup and teardown, especially beneficial for mobile or remote operations.

Transport & Mobility:
Weighing approximately 52,000 pounds and capable of travel speeds up to 3.2 mph, the AT120 offers better mobility between job sites than other large drills in its class.

This machine is ideal for utility installation, pipeline work, and rock-heavy bore paths that demand consistent torque and precision.

The AT120 is designed for drilling contractors who demand performance in extreme conditions—whether it’s hard rock, cobble, or long-distance runs. The dual-pipe system isolates inner and outer pipe rotation, giving operators fine-tuned control and extended tooling life. Combined with Ditch Witch's reputation for service and support, the AT120 is more than just a powerful drill—it's a long-term asset that increases uptime and jobsite productivity.
