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).
