5. Describe DTH bits.
To drill holes in a range of rock types, down-the-hole (DTH) hammers are used in conjunction with down-the-hole hammers. The hammer drill bit is built with a splined drive to rotate the drill bit underground when used in conjunction with a down-the-hole hammer.
6. What is a hammer for down the hole?
In essence, down-the-hole drilling (DTH) uses a drill hammer at the drill string's base. Drilling is dependent on three factors: air, rotation, and bit load (weight). Together, these active components efficiently fracture rock.
7. How does down-the-hole drilling work?
A down-the-hole drill rig, commonly referred to as a DTH by most professionals, is basically a jackhammer that screws onto the bottom of the drill string. The rapid hammering action breaks the hard rock into small chips and dust, which are expelled through the fluid (air, water or drilling mud).
