PD300 Hydraulic Rock Drill
The PD300 hydraulic rock drill is a compact yet powerful drilling solution designed for small to medium-scale mining, tunneling, and construction applications. With a nominal power class of 12 kW and an impact energy of 300 J, it offers efficient performance for hole diameters up to 76 mm and drilling depths up to 20 m.
Despite its lighter weight of 170 kg, the PD300 delivers high percussion efficiency and stable torque, ensuring reliable operation even in challenging rock conditions. The integration of Danfoss rotation motors guarantees smooth and precise rotation, while its air-oil mist lubrication system minimizes wear and extends service life.
The PD300 is also equipped with dual flushing options (air/water), enabling clean hole conditions and optimal drilling performance across different environments.
