Dual Rotary drills feature a unique lower drive that advances casing independently of the top drive while simultaneously advancing the drill string. The Dual Rotary method has been proven to be effective in the most challenging overburden conditions. Advantages over conventional rotary include straighter cased holes, increased depth capability, increased rate of production, and ability to use threaded casing.
Our Foremost brand units advance casing strings as large as 24” in diameter. These units are commonly used for domestic and municipal wells, and construction applications such as foundation piles, industrial and exploration work.
