We have many years of experience in manufacturing coring drill rods. With a large inventory always in stock, we focus on providing the most cost-efficient products without compromising quality.
Our drill rods and casings are manufactured using premium quality cold-drawn seamless tubes and high-grade tools for diamond core drilling. These alloy steel tubes ensure excellent tensile strength and elongation characteristics, processed via high-technology CNC machines.
By integrating the latest technological developments, we manufacture upseted drill rods. Using tubes with larger internal diameters where the wall thickness of both ends is increased for threading, the final product is significantly lighter. This results in rig depth capacity increases of up to 30%. The heat treatment process further ensures durable and resistant threads.
