The CME fluted kelly provides a combined 11-foot feed stroke, allowing drillers to use 10-foot drill rods. This means fewer rod connections and less rod handling. The 2 5/8-inch fluted kelly and chuck assembly is available in either manual or hydraulically-actuated configurations. Or, if you’re using larger rods for larger diameter holes, a 3½-inch OD fluted kelly and hydraulic chuck assembly is also available. www.cmeco.com
