  • INQUIRY


A down the hole hammer, usually called DTH hammer is by far one of the fastest ways to drill hard rock. In DTH drilling, the percussive DTH hammer is located behind the drill bit, inside the hammer, a piston powered by compressed air gives the DTH bit its striking power, while the DTH hammer casing gives guidance to the drill bit; the drill string rotates while the drilling hammer continuously strikes down into the rock. The drill rods transmit the necessary feed force and rotation to the DTH hammer and bit, as well as compressed air for the DTH hammer, more drill rods are added to the top of the drill string as the hole gets deeper. The fast hammer impact breaks hard rock into small particles, which are blown up by the air exhaust from the DTH hammer.
