New Drills for Underground and Surface Applications

Atlas Copco is now offering the COP 2238, a new 22-kW hydraulic rock drill for the 51- to 76-mm hole-diameter range in drifting, tunneling and extension drilling applications. According to the company, the new drill’s proven dual-damping system ensures that the bit maintains constant contact with the rock, re-tightening drillstring joints between each impact. This technology allows the rock drill to operate at a consistently high impact frequency, resulting in a higher penetration rate even during extension drilling of probe or grout holes. In addition, the damping system absorbs excess energy from each impact, reducing wear on both the rock drill and drill string. The COP 2238 is claimed to be easy to service, with several wear parts replaceable without having to demount the drill from the drill rig. The COP 2238 also has many parts in common with the COP 1838 series, which offers an opportunity for users to reduce on-site inventories. The COP 2238 can be used with both shortand long-shank adapters and with R32, R38 and T38 threads. Four different rotation motors are available.

Atlas Copco also introduced an upgrade to its popular COP 1238 rock drill. The new COP 1240 is specifically designed for surface drilling applications. It has a larger, more durable driver which helps to reduce wear and keep operational costs low, while allowing efficient drilling of holes in the 40- 102 mm range. The 1240’s design is uncomplicated, according to the company, and easily accessible parts make it easy to maintain. The new drill shares the same housing as the larger COP 1840 for improved robustness and durability. There are three shank adapters to choose from, depending on the drill steel being used; i.e., R32, T38 or T45. The latter two are also available with extractors.
