In parallel with material improvements, design optimization played a critical role in enhancing drill rod performance
mine 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.

Beyond the physical insertion, the positioning and orientation of the rock bits are equally crucial
insert rock bits. Engineers use advanced software to map out the drilling path, ensuring the bits are aligned optimally for maximum effectiveness. This not only enhances drilling speed but also reduces wear and tear, extending the lifespan of the bits.
