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.
Another notable benefit is their compatibility with various drill rigs. Many modern drilling machines are designed to accommodate drill rods of different sizes, and a 20mm rod fits well within this spectrum. This compatibility reduces downtime during rig setup and allows for faster transitions between different drilling tasks.
