This lightweight tool is designed for drilling blast, anchor and rock-splitting holes. Used for example by contractors, armies and utilities who want convenient and efficient drilling without large compressors. With standard integral steel, it drills diameters of up to 50 mm (2”) and depths down to approx. 6 m (33 ft) by using hydraulic power for impact and rotation. A small additional compressor is needed for flushing. Without air flushing, it can be operated wholly by hydraulics and can drill holes of down to 1 m (3.3 ft) with a spiral hammer drill.
