The DTH hammer operates through compressed air, which is pumped through a series of valves and chambers within the hammer. When the air pressure builds up, it drives a piston that strikes the drill bit, creating a powerful force that breaks the material. This process continues in rapid succession, allowing the drill bit to penetrate the ground efficiently. The design of the DTH hammer allows for a larger drop height of the piston than traditional rotary drills, resulting in higher impact energy and better drilling performance.

A DTH hammer is a type of percussion drilling tool that functions by delivering a series of rapid impacts to the drill bit, which then breaks the rock or other materials beneath the surface. The term down-the-hole refers to the hammer being placed directly above the drill bit, allowing the energy from the hammer to be transferred efficiently into the drill bit. This method enhances the speed and effectiveness of drilling operations, particularly in hard rock formations.
