Terex Reedrill's R20T is claimed to be the first track drill to provide 360-degree rotational capability, significantly improving its access and positioning capability when working in difficult areas. In addition, the ability to rotate completely on its undercarriage and safely tram down a steep embankment adds to the drill's safety and productivity. Nicknamed the “Texas Twister,” the R20T is a self-contained, hydraulic unit mounted on a Caterpillar 312 excavator undercarriage. It is fitted with Reedrill's HPR45 hydraulic rock drill, which is capable of sinking blastholes from 2½ to 3½ inches in diameter. The HPR45 is mounted on a newly designed cylinder/cable feed system that reduces noise levels and provides for smoother operation. The R20T is equipped with the hydraulically operated SmartDrill drilling system, which features self-adjusting feed force logic designed to reduce operating costs and extend the life of consumables.
