The Mole was initially designed as a hollowstem drill rig, but we added direct push technology to make it more versatile. The rig is equipped with high and low torque drill heads, plus a cathead for standard ASTM sampling. The Mole is also ideal for pushing Shelby Tubes. Its compact design and rubber tracks fit through a 54 in. opening and allow the rig it to track lightly—at only 7 lbs. P.S.I. under the treads. The Mole can also drill under a 9 ft. over head. With an onboard air compressor, a grout pump, and a water tank on the support truck, the Mole brings unparalleled speed, power, and versatility to limited-access drilling.
