DR DECK KITS All the versatility of the Foremost Dual Rotary Drill can be mounted on virtually any non-standard North American Chassis. Options for 700 HP onboard compressor models, or lighter 260 HP non-compressor models. Both configurations have the standard 3” air plumbing incorporated into the drill deck and mast. The DR Deck Kit is designed for many types of on-road and off-road conditions and the shipping frame is included with the drill purchase. 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 SHOE A carbide-studded casing shoe is welded to the casing bottom. The shoe I.D. is flush with the casing I.D. so that there is no reduction in the bore hole diameter when switching to open-hole drilling.
