2025 American Augers Maxi-Rig DD600
The future of directional drilling isn’t coming. It’s already here.This drilling machine has 600,000 lbs of thrust and pullback and 100,000 ft·lbs of torque, so you can take on big jobs in tough soil conditions—but this directional drill is about more than raw power. With a design based on customer feedback, it also boasts state-of-the-art, industry-leading HDD features, making it the best high-torque directional drill for long-distance boring.
Features may include:
- Cable and hose connections are waist-high for yet another way to make setup quick and simple.
 
- With a weight of just 95,000 lbs—including wrenches and full fluids—it meets standard permitting, saving you time and money
 
- A hydraulic catwalk allows for one-person setup, and fold-down handrails don’t have to be removed for transport.
 
- The front foot design offers a simple pinned retention foot that’s both strong and easy to connect and disconnect.
 
- Diesel exhaust fluid (DEF) isn’t required, simplifying the engine, making maintenance easier, lowering costs, and eliminating downtime.
 
- A new, spacious cabin gives you a wide-angle, unobstructed view of the drill.
 
- Interior red lights allow for nighttime operation without glare, and jobsite LED lighting is included on the exterior of the cabin.
 
- Ducted heating and air conditioning in the cabin make things comfortable in any weather conditions, and sliding windows provide improved airflow
 
- An improved steering location offers even better control to auxiliary crew members.
 
- Designed to transport without removing the wrenches, you’ll save hours in disassembly time every time you need to move the DD600.
 
- Route blow-down through the foot and into the pit, increasing comfort for both the operator and the crew.
 
- An open-top wrench design offers better visibility and makes things easier than ever to service. Plus, floating die heads that conform to the pipe offer better grip and reduce die wear.
 
- Dual rotation cylinders guarantee even and higher breakout force for extra reliability.
 
- Patented, free-spin capability allows the DD600 to operate as a catch rig for breakout, increasing jobsite versatility.
