ST180 It is widely used for water well drilling, geothermal air-conditioning project and other boreholes, especially applicable to mountain area and rock formation water engineering.Much higher efficient than the traditional mud rotary drill rigs, creating the considerable economic benefit for users. Especially solve problems to drill hard rocks that the traditional rotary drilling rig meet and it can work with both air compressor and mud pump
