Down the Hole Hammer Drilling
Down the Hole Hammer drilling is a high-efficiency method used to penetrate very hard rock formations. The percussive drilling process delivers excellent performance where conventional rotary drilling methods are ineffective or impractical.
Application
DTH hammer drilling uses a percussive bit driven by high-pressure air, making it one of the most effective methods for drilling hard rock. It is commonly used in high-strength strata and can be applied to shallow or deep drilling. The method is also used in water well, oil, gas, and exploration drilling, and can be combined with large diameter bored piles to improve drilling efficiency in rock sockets.
Advantages
Extremely efficient in hard rock- Suitable for smaller piling and anchoring rigs
- Improves productivity when combined with bored piles
