DR 40 Dual Rotary Drill The DR-40 handles casing up to 40” (1,016 mm) in diameter. The DR-40 excels in large diameter construction and industrial water well applications. Standard configurations include tracked undercarriage or crane carrier with deck engine and on-board air compressor. FEATURES Since acquiring the Dual Rotary technology from Barber Industries in 1993, Foremost has continually updated, refined and expanded the DR line with the goal of enhancing its functionality and extending its range of applications. Today, Foremost offers several DR models, each packed with features that deliver heightened safety, productivity, and profitability across a variety of drilling activities. CYCLONE COLLECTOR The optional cyclone sample collecting system slows discharge velocity to allow accurate and continuous sampling of the formation. DISCHARGE SWIVEL All drill cuttings rise to the surface between the drill pipe and casing, and exit through the discharge swivel attached to the top of the casing. The discharge swivel directs cuttings to a safe dumping point or to an optional cyclone collection system CASING JAWS Rotation and feed forces are effectively transmitted from the lower drive to the casing via a set of three carbide inserts. Casing jaws are available for all common casing sizes and can be changed out quickly in the field.
