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.
