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 primary difference between the 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.
3.Can you directional bore through rock?
One of the most significant milestones in the evolution of HDD, however, was the development of the technology. As technology has advanced, midsize drilling equipment now has the capability of effectively drilling and steering in rock.
