Large Downhole Drill
As the largest member of Ingersoll-Rand Co.’s Quantum Leap family of downhole drills, the QL200 offers the ability to drill 17.5-inch to 36-inch holes. The QL200 is a productive large-hole DHD specially designed for water well, construction, ground engineering, municipal and oil and gas applications. Its shank design and extra-large one-inch diameter inserts are said to increase bit reliability and life. Another benefit of the QL200 is that it works efficiently on high-volume single-stage compressors. Ingersoll-Rand Co.
