What kind of hole is created using percussion drilling?

Percussion drilling is a technique commonly used for creating deep holes, primarily in geological exploration and construction projects. This method involves repeatedly striking a drill bit against the material to break it up, allowing for efficient penetration into the ground. The action of rapid and repeated impact on the drill bit allows it to reach significant depths, making it ideal for applications where deep access is needed, such as when searching for groundwater or minerals.

In contrast, narrow, shallow, and wide holes are typically associated with different drilling techniques or applications. For example, a narrow hole might indicate a method designed for precision drilling, while a shallow hole often reflects light drilling techniques where extensive depth is not necessary. Understanding the characteristics of percussion drilling helps in recognizing its suitability for deep explorations, confirming that the appropriate term for holes created by this method is indeed deep.
