HFDX-5
General Introduction
The new model HFDX-5 of hydraulic core drilling rigs is developed with advanced international technology. The onshore oil rig is easy to operate and maintain with superior performance compared to traditional core drilling rigs. This drilling equipment makes large diameter holes in exploration and prospecting projects in the fields of geology, metallurgy, and coal, petroleum, and natural gas mining.
