The fully hydraulic open-pit rock drilling rig is one of the most widely used drilling machines in domestic construction departments, mainly used in open-pit mines, the cement and building materials industry, the stone market, construction, and road engineering quarry construction, etc. Currently, most of the machines used domestically are crawler-type, single-arm drilling mechanisms, mainly used for drilling downward blasting holes, with hole diameters usually ranging from 64 to 102 mm, and the maximum drilling diameter can reach 127 mm, with drilling depths mostly in the range of 15 to 20 m. They use D38 mm, D45 mm, and D51 mm diameter round coupling rods or MF drill rods, as well as ball tooth drill bits with diameters ranging from 64 to 112 mm.

Now, with the rise of infrastructure engineering construction projects and the building materials and stone market, the number of hydraulic rock drilling rigs purchased by domestic construction units is also continuously increasing. According to relevant data, domestic construction units purchase about 100,000 various hydraulic rock drilling rig drill rods each year. Therefore, further improving product quality will bring greater development opportunities for the domestic drill rod product market.
