In top hammer drilling, the hammer produces a percussive force on the drill rods which is transmitted to drill bits. Feed device is attached with the hinged boom to a mobile unit. Striking and rotation make it possible to drill holes in hard rock. Cuttings are flushed up from the bottom of the hole by means of pressurized air or water. Top hammer drill are primarily used in mining, construction and quarrying of rock material.
