Foremost DR-24

Foremost_DR_24

The DR-24 will set casing up to 24 inches (610 millimeters) in diameter. The model is commonly used for domestic and municipal wells, construction applications such as foundation piling projects, and holes for hydraulic elevator jacks. The DR-24 is available in PTO or deck engine configurations and can be mounted on a truck, trailer or self-propelled tracked carrier. It is available in a stock tandem or tridem configuration. Foremost Dual Rotary drills feature a comparably lower rotary drive that is used to advance steel casing through unconsolidated overburden, such as sand, gravel, glacial till and boulders. Pullback, pulldown, and rotational forces are effectively transmitted to the casing via high-strength steel jaws with carbide inserts. An independent rotary top drive simultaneously handles a drill string equipped with a down-the-hole hammer, drag bit or roller cone bit. Cuttings are typically evacuated with air, but Foremost DR Drills can also be configured with pumps for mud or flooded reverse circulation drilling. The top and lower drives feed independently, meaning that the bit position can vary relative to the bottom of the casing. Once the desired casing depth has been achieved, the DR continues drilling open-hole like a conventional top drive drill. With a Foremost DR Drill, there is no need to trip out or change tools when transitioning to open-hole drilling.www.foremost.ca
