CME-45C Drill RigCME-45C
This is one of our most versatile drill rigs. It can be mounted on a truck, trailer, skid, ATV or the CME-300 rubber track carrier. It can even be made helicopter-portable. A skid/trailer configuration gives you two options. You can use the drill as a conventional trailer mounted unit, or you can easily remove the drill from the trailer and skid it up or down steep slopes, or through narrow openings. The CME-45C has the same drilling capabilities as the CME-45B but can also be equipped for angle drilling.

CME-85 Drill Rig CME-85
This rig has big power. And it was built to handle that power. There are no compromises. Everything is heavy-duty. The right angle drive, the rotary box, the frame, every component was specifically designed to take the forces this drill can produce, and then some. Like all CME drills, the CME-85 is designed with many features for easy operation. A patented hydraulic kelly bar lift system, for instance, makes coupling and uncoupling the kelly bar to the right angle drive virtually effortless. The transmission has six forward gears so there’s a rotation speed and torque combination for just about any situation, from large diameter auger drilling to deep rotary jobs. With 22,900 foot pounds (31,048 Nm) of torque, the CME-85 can handle hole sizes up to 18.5 inches (47 cm) in diameter using hollow-stem augers.

CME-95 Drill Rig CME-95
Equip the CME-95 with a string of CME extra-heavy-duty augers and you’ve got the ultimate combination for really big drilling jobs. No other drill is going to do the job for you faster or more efficiently. The rugged mechanical rotary drive is available with up to 36,100 foot pounds (48,945 Nm) of torque for turning large diameter augers. The power shift transmission, with four gears in both forward and reverse, provides a rotation speed and torque combination for any situation. And an independent, hydraulically actuated low speed drive system gives you infinite regulation of spindle rotation from 0 to 100 rpm. It makes lining up auger connections and making or breaking drill rod connections easy. It also works exceptionally well in down-the-hole hammer drilling operations. In auger drilling applications, the standard CME-95 can drill up to 18.5 inch (47 cm) diameter holes. It can also be equipped for drilling up to 25 inch (63.5 cm) diameter holes.
