Moreover, advancements in drill rod technology have led to the development of specialized rods for specific tasks. For example, down-the-hole (DTH) drill rods, with their improved efficiency and penetration rates, have revolutionized hard rock drilling. Similarly, rotary-percussion drill rods, combining rotation with hammer action, have proven effective in soft to medium-hard rock conditions commonly found in coal mines.
