Center Rock RF60 Downhole Drill
May 28, 2018
Introducing Center Rock’s new RF60 downhole drill. Developed with the water well contractor in mind, this hammer utilizes a high productivity valved cycle, which can be tuned to operate on 900 cfm to 1,250 cfm with incredible efficiency. Heat- and wear-resistant steel air control valve maintains peak performance over the life of the hammer and a reversible casing helps maximize longevity of external components. According to Center Rock, testing has proven the RF60 to be an industry-leading performer, especially under high water volumes. www.centerrock.com
