HT-4 is a new model core rig drilling with high speed diamond-bit designed and manufactured by Yongkang Hongtian Industry & Trade Co., Ltd. Basing on the exploration technique development in China, considering the geological condition of the country. The HT-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.
