I. EPT

HF-44A Main Drill, a new type of item with increased capacity, is a type of EPT-EPTn, spindle, diamond-bit, little-diameter core drill with relatively EPTful drilling force. It is mainly ideal for exploration of metal or non-metal reliable EPTral ore mattress. It is broadly utilized in main drill with diamond little bit or difficult tungsten-carbide-tipped little bit and diamond little bit in the subject of geology, metallurgy, coal EPT, hydrological and engineering drilling. It can also be employed in the fields of superficial-zone

petroleum and natural fuel mining, EPT workings air flow and water discharge tunnel drilling as nicely as basis EPT building in large diameter. It is in reasonable construction, ligEPT weight, EPTful capacity, multiuse, constant efficiency, higher duty and higher stXiHu (West Lake) Dis.Hu (West Lake) Dis.rdization and EPTization.
