Down the hole bits, DTH bits

Image
Product description：DTH bit, usually called down the hole bit, a piston of DTH hammer powered by compressed air gives the DTH drill bit striking power to break hard rock into small particles. 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 drill bit its striking power, while the DTH hammer casing gives guidance to the DTH drill bit; the drill string rotates while the drilling hammer continuously strikes down into the rock. The  DTH 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. We supply a comprehensive range of  DTH Drill Bits  in DHD, QL, SD and Missio...
