Pneumatic down-the-hole (DTH) hammer is a pneumatic drilling tool using compressed air as a power source. It is suitable for drilling in pebble, gravel, and hard rock strata. It is often used in building pile foundation construction, bridge, mining, geological exploration, hydrological wells, and other fields.

The primary difference between top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in the industrial equipment makes contact with the bit during the down-the-hole drilling method. The top hammer drilling method's activity is concentrated at the very top of the drill string.

Top hammer drills are primarily used in mining, construction and quarrying of rock material. Top hammer drilling, combined with the "drill and blast" method, makes the whole excavation process extremely efficient.
