- 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.
- Drill shanks are the connection point between the drill rod and the rock drill machine. They come in different sizes and shapes to fit various machine types. The quality of the drill shank is crucial for maintaining a stable connection between the machine and the drill rod during drilling operations.
