The fast hammer action breaks hard rock into small flakes and dust and is blown clear by the air exhaust from the DTH hammer. The DTH hammer is one of the fastest ways to drill hard rock. Now smaller portable drilling rigs with DTH hammers can drill as fast as much larger truck rigs with this newer technology.
