About DTH Rock Drill

DTH Rock Drill is a type of drilling equipment used in mining, quarrying, construction, and exploration activities. It is designed to drill holes in rock formations by using compressed air to power a hammer-like mechanism that strikes the rock surface, allowing for efficient penetration. DTH Rock Drill employs a hammer mechanism, also known as a percussion system, to break the rock surface. This mechanism typically consists of a piston that strikes the back of a drill bit with high impact force, creating a series of rapid impacts that fracture and crush the rock.
