Shandong Yanggu Zuanxing Drilling Tools Factory mainly produces stone drilling tools, hydraulic rock drills, pneumatic rock drill spare parts and soft-rock drilling tools. We also have all specifications of platy and post-type drill bits, drill shanks, drill rods and connecting sleeves. We imported French hyd200-type and hyd300-type hydraulic rock drill machines, which are widely used in China's stone drilling working lines. On this base, we have developed stone drilling machines and matching drilling tools used by tap holes of blast furnaces, which are widely applied in iron and steel enterprises in China. We initially passed ISO9001 quality system management certification, which ensured and proved the quality of our products.
