    The DR-610C is a unique hydraulic foundation piling drill that incorporates Foremost's proven Dual Rotary technology to simultaneously drill and advance steel casing in difficult formations. It also provides added flexibility for continuous flight and kelly auger drilling applications.
    The DR-610C is designed to set steel casing up to 24" (610 mm) in diameter and has a long stoke via a rack and pinion system. The standard configuration is crawler-mounted, providing 360 degree rotation to quickly load drill pipe and casing from any angle. The DR-610C can also be fitted to other carrier configurations as well.
