This is our largest and most powerful drilling machine. Specifically designed for drilling large diameter shafts up to 14 feet, this rugged crawler-based platform features a drill unit that will reach over and turn casing, making it a versatile tool for the most demanding job conditions. This advanced hydraulic rotary rig features a self-erecting mast to allow maximum torque value along its complete length.
The addition of the Watson 4400 to our fleet is evidence of our pursuit of the ideal drilling machine.
