Lightning Rod drill rods feature a quick-change male and female rod and is designed to work in surface drill and blast applications. With a diameter range of 33 to 60 mm, and lengths ranging from 8 to 14 feet, the rods from Boart Longyear can cover multiple project-specific needs with a wide range of sizes and thread forms. The male and female ends have been treated for high wear-resistance and they eliminate conventional coupling to allow quick, automated subtractions and additions to the drill string, the company says. The premium mid-body steel design gives the rod a strong foundation with efficient energy transfer and has been optimized for air flushing.
