5. What are DTH bits?

DTH hammer heads are used with DTH hammers to drill holes in a variety of rock types. Used in conjunction with the drill hammer, the drill hammer bit is designed with a spline driver for rotating the bit underground.

6. What is a drill hammer?

Underhole drilling (DTH) essentially involves a drill hammer at the bottom of the drill string. It relies on three elements for drilling: bit load (weight), rotation, and air. These active elements combine to effectively break up rock.

7. How does subhole drilling work?

A submerged-hole drill, often referred to by most professionals as a DTH, is basically a jackhammer screwed into the bottom of the drill string. Rapid hammering action breaks the hard rock into small chips and dust, which are discharged by fluid (air, water, or drilling mud).

8. What is an impact drill?

The hammer drill is designed to drill quickly through brittle materials such as concrete by combining the rotary action of the bit with the hammering action, which moves the bit in and out of the hole along the axis of the bit to provide a striking action position while drilling motion.
