Down-the-hole (DH) drill pipes are made of hollow, seamless steel tubing with threads at both ends—one internal and one external. They are primarily used to connect drilling rigs and drill bits, transmit torque and axial pressure, and supply compressed air to the impactor through their central hole. They can also be used to connect drill rods themselves. DH plays a crucial role in rock drilling operations and is widely used in mining, foundation engineering, and water well drilling.
