About H.H. Drill-Tech

H.H. Drill-Tech Drilling Machinery Co., Ltd. is a high-tech enterprise specializing in the design and manufacture of geotechnical drilling equipment in China. Established in 2015, the company inherited all assets, staff, and expertise from the former Lianyungang Huanghai Machinery Co., Ltd.

Originally founded in 1970 as the Northwest Exploration Machinery Factory under the Ministry of Geology and Mineral Resources, the factory was relocated to Lianyungang, Jiangsu Province in 1995. With over five decades of accumulated industry knowledge, we have become a national leader in geological drilling technology.

Our 191,400 m² production base houses 103,700 m² of construction space and over 450 sets of advanced production and testing equipment. We are fully equipped for structural welding, machining, heat treatment, painting, and full assembly processes.
