    8'' QL80 DHD380 SD8 Mission80 Down The Hole DTH Drill Hammer for Coal Mining

    Product description
    A down-the-hole drill, usually called DTH by most professionals, is basically a mini jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small flakes and dust and is blown clear by the air exhaust from the DTH hammer.

    Product Advantages:
    1.Fewer internal components minimize service requirements.
    2.Valveless, high frequency design ensures smooth operation.
    3.Hardened wear sleeve for optimum wear resistance even in the most abrasive conditions.
    4.Multi-start threads on backhead and chuck ensure easy coupling/uncoupling of hammer.
    5.All critical internal components are heat treated under strict control to maximize tool longevity.

    Face shape Features
    Drop Center
    For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
    Concave Face
    The all-round application bit face special for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
    Convex Face
    For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
    Flat Face
    This kind of face shape is suitable for very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
    Double Gauge Face
    This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.

    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.

    DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
