  • High Air Pressure Down The Hole Bits - China

    price: contact company for price

    The down-the-hole drilling is used to produce large-diameter holes in

    rocks, usually in the initial stage prior to blasting, but it is also

    used in non-blasting applications. DTH drilling are used mostly in

    mining quarries but can be used in a variety of other construction

    applications. The DTH drilling method is growing in popularity, with

    increases in all application segments, including blast-hole, water well,

    foundation, oil & gas, cooling systems and drilling for heat exchange

    pumps. Applications were later found for the DTH method underground,

    where the direction of drilling is generally upwards instead of
