  • The advancements in material science have led to the development of advanced rock drilling rods with improved properties. High-tensile steel, titanium alloys, and even composite materials are being explored for their potential in enhancing rod performance, durability, and efficiency.
  • In parallel with material improvements, design optimization played a critical role in enhancing drill rod performancemine extension drill rod. The introduction of tapered threads reduced stress concentrations at thread connections, minimizing the risk of fractures. Additionally, the implementation of advanced coatings such as titanium carbonitride (TiCN) provided an extra layer of protection against abrasion and wear, extending the service life of the rods significantly.
