Drill Down on Productivity.
As the industry’s go-to machine, the DD-440T maximizes your productivity wherever you drill. This unit gives you up to 60,000ft lbs of rotary torque and 440,000lbs of maximum thrust/pullback, so it’s always ready for tough drilling. For especially tough conditions, you can spec your machine with an optional maximum of 80,000ft lbs of rotary torque. And, you get the widest range of thrust/pullback power of any track-mounted drill for optimum performance in any other conditions.

- American Augers’ standard slip spindle that can be easily changed when needed, minimizing costly downtime.
- Full-length traveling wrenches to assist with stubborn tool joints and allow pulling tooling up on the drill frame.
- New 3.5” fluid course for up to 825gpm of drilling fluid flow allowing faster drilling for longer.
- Standard telematics for service information and office communication with daily work progress.
Reliability
- Simple system design maximizes durability and makes maintenance easier.
- Backspin-resistant motor is more reliable in difficult conditions that can cause other motors to fail.
- Redesigned metal engine enclosure prevents costly downtime by safeguarding critical components.
- Adjustable torque-limiter protects the machine and prevents costly downtime.
Safety
- Cab designed for open operator sightlines to maximize jobsite safety.
- Standard ZAPALERT electrical detection device alerts crew to the possibility of striking an underground powerline.
- Easily-accessible emergency shutdown switch at operator’s controls.
- Equipped with Quiet-Pak technology to minimize noise, protecting the crew’s hearing and preventing noise pollution.
