Applications & Performance
Also known as extension rod, extension drill steel, or MF rod (Speedrod), available in both hexagonal and round cross sections. Hexagonal rods provide greater rigidity, improved energy transfer, and enhanced flushing, while round rods are lighter and ideal for extension drilling applications.
Featuring a duplicate thread system on each end, these threaded drill rods significantly improve drilling precision when used as the first rod in a drill string. The speed rod design delivers straighter holes and increases penetration rates by at least 10% in optimal rock conditions compared to traditional rod and coupling sleeve systems.
