Description

The CMM2 in-the-hole (ITH) production drill, including a hydraulic rod lock, breakout wrench, and pipe clamp, is designed specifically for easy rod change-outs in the field. High performance and accuracy. The CMM2 features high-performance DHD cluster drills/reamers (up to 610 mm (24 in.)) for production stope slot raises and sublevel caving; these operating pressures up to 24 bar (350 psi) air pressure. The direct-connected rotary head and telescopic feed cylinder are standard. In addition, the CMM2 includes a hydraulic centralizer for accurate hole orientation. Mast and towers: The mast, with replaceable wear strips, features 360° tower rotation, which enables full-circle drilling without the need to repine. The CMM2 includes towers for rod lengths from 1.0 to 1.82 m (3 ft. 3 in. to 6 ft.), a 1.0 m (38 in.) tower slide, and dual-tower stabilizing jacks and hydraulic tower extension.
