A rock drilling rod, typically made from high-strength alloy steel, is a cylindrical shaft that connects the drill rig to the drill bit. Its primary function is to transmit the mechanical energy from the drilling machine to the bit, facilitating the drilling process. The rods' durability and resistance to deformation under immense pressure are crucial attributes, as they are subjected to rigorous forces during drilling operations.

In addition to extending the reach of the core drill bit, extension rods also play a crucial role in maintaining the stability and alignment of the drill bit during operation. This is especially important when drilling in hard or uneven surfaces, where maintaining a straight and consistent drilling trajectory is essential for achieving accurate results. The extension rod helps to absorb vibrations and ensure that the drill bit remains in place, reducing the risk of deflection or deviation from the desired drilling path.
