Material selection for integral drill rods is crucial to their performance and longevity. Typically made from high-speed steel (HSS) or carbide, these rods are heat-treated to withstand the stresses of high-speed drilling and the friction generated during thread formation. HSS offers a good balance of toughness and hardness, while carbide provides superior durability and cutting efficiency, making it ideal for drilling through harder materials.
