Foremost Dual Rotary (DR) rigs offer unmatched performance in unconsolidated formations. Foremost DR rigs feature 2 independent rotary drives for simultaneous drilling and casing. Drill string can advance ahead, behind or flush with the casing. No casing hammers, under-reamers or drilling mud required. Once the desired casing depth is reached, DR's continue to drill open-hole like a conventional air rotary rig.
