Audited Supplier This small-sized type of HFY-500 is the all-hydraulic core driller, which can achieve the drilling functions of hydraulic drive, hydraulic feed, hydraulic pullout. HFY-500 could fulfill the demand of variable speed in a proper range of rotating speed. HFY-500 has the ability to adapt the diferent accessoris for the different requirements of drilling parameters under the different operating conditions. This driller is mainly suitable for the technological requirements in fixed deposits diamond and cemented carbide situations' surfaces or tunnels , and for the all the process wire line coring requirements during drilling process. HFY-500 can be used in various drilling holes construction of geological exploration, hydro geologic drilling holes, anchorage, dam grouting, cofferdam grouting and pile foundation.
