PD380L Hydraulic Rock Drill
The PD380L hydraulic rock drill is a high-performance drilling solution designed for underground mining, tunneling, and construction projects that require efficiency, precision, and durability. With advanced hydraulic control and a robust structure, it delivers consistent drilling power even in the toughest rock formations.
Engineered for productivity, the PD380L combines strong percussion energy with reliable torque output, ensuring deeper penetration and reduced drilling cycle times. Its compact and lightweight design enhances maneuverability, while the integration of Danfoss rotation motors provides exceptional stability and reliability during demanding operations.
The air-oil mist lubrication system minimizes wear on internal components, extending the service life of the drill. Its dual flushing system (air/water) further improves hole cleaning efficiency, ensuring smooth and continuous drilling performance.
