Down-the-hole hammer drilling is a technique used primarily for drilling boreholes in hard rock applications. It employs a pneumatic hammer, situated directly at the drill bit, to deliver high-impact blows that effectively break up the rock. This method contrasts with traditional rotary drilling, where the drill bit operates at the surface and relies on torque and weight to penetrate the ground.

Furthermore, the dimensions of the 20mm drill rod provide a perfect balance, ensuring that it is neither too bulky nor too fragile. This balance allows for efficient drilling without excessive energy consumption. The weight of the rod also plays a crucial role in its transportation and handling, making it easier for workers to maneuver it on-site.

4. Manufacturing In manufacturing, spiral drill bits are frequently employed in creating holes for assembly fixtures and machinery setups, providing both function and precision.
