multifunctional borehole drilling rig HF-42A for core drilling ,water well, piping

Applications of the HF-42A borehole drilling rig

HF-42A borehole drilling rig is a kind of core drill driven With tungalloy-carbide-tipped  bit and diamond-bit, small-diameter. It is mainly suitable for exploration of metal or non-metal solid mineral ore bed. It is Widely applied in the 

field of geology, metallurgy, coal mine, hydrological and engineering drilling. It can also be used in the 

fields  of  superficial-zone  petroleum  and  natural  gas  mining,  mine  Workings  ventilation  and  Water 

discharge tunnel drilling as Well as foundation pile construction in large diameter.
