Main Technical Specifications:

XY-4 is a new model core rig drilling with high speed diamond-bit designed and manufactured with the exploration technique development in China, considering the geological condition of the country.

The XY-4 core rig has 8 speed grades. Its highest speed can be 1588rpm; And it can also work at 101rpm, a very low speed. So the rig has a strong applicability and a large serviceable range. Besides mainly applied to earth surface and gallery exploration of solid deposits by using diamond or tungsten carbide bits, it could be applied to geological exploration and prospection, and it also could be used for superficial petroleum and natural gas exploration and for groundwater finding drilling. It could be applied to the projects drilling of dam grouting and sap ventilation etc.

XY-5 CORE DRILL, is the improved product based on XY-44 core drill and integrated with the advantages and characteristics of various core drills manufactured in China and abroad, is a kind of hydraulic-driven, spindle, diamond-bit, small-diameter core drill with fairly powerful drilling force. It is mainly suitable for exploration of metal or non-metal solid mineral ore bed. It is widely applied in core drill with diamond bit or hard tungsten-carbide tipped bit 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, mines’ gallery ventilation and water discharge tunnel drilling as well as large-diameter hole foundation stake drilling.
The machine is fit for engineering works of inclined and vertical hole drilling.
