FAQ:
1. What is hole hammer?
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.
2. Is top hammer drilling vs down-the-hole drilling?
The fundamental distinction between top hammer and down-the-hole drilling methods is the location of the hammer. During the down-the-hole drilling method, the hammer in the industrial equipment makes contact with the bit. The action of the top hammer drilling method is concentrated at the very top of the drill string.
3. What is a top hammer used for?
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.
