5. What is DTH Bit?
Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground.
6. What is DTH hammer?
Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock.
7. How does DTH drilling work?
A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud).
8. What is a hammer bit?
Hammer drills are designed to quickly drill through brittle materials like concrete by combining the rotary action of the drill bit with a hammer action that moves the drill bit in and out of the hole along the bit's axis to provide a pounding action along with the drilling motion of the bit.
