    High Performance DTH Drilling Tools DHD360 Down The Hole Hammers And Bits


    High Performance DTH Drilling Tools DHD360 Down The Hole Hammers And Bits

    Product description

    DTH hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling.
    Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs.


    Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes. Our variety of Down the Hole (DTH) bits is manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life. We offer a comprehensive range of standard and made to order drill bits on an extensive selection of shanks with a wide variety of head designs to suit every project.

    Product features

    DTH hammer:
    Valveless air distribution. More reliable.
    Simple design of the piston. Long life.
    More efficient energy transfer, fact drilling speed, lower air consumption and lower oil consumption.
    Fewer internal parts, simple structure, long life, less failure and easier to maintain because all the parts are heat treated.
    Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.


    DTH bit:
    Strict quality controlling
    Selected high quality special steels and carbide
    Produced by CNC machines
    Simple and reasonable design, Low problem rate
    Low air consumption, smooth drilling, Maximum impact power, High penetration rate




    Product application

    At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering. it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain. At the drilling hole of dia.105mm-dia.254mm, a plenty of the DTH drilling tools are used.
