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 effi cient 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 fl ushing. Without airflushing, it can be operated wholly by hydraulics and can drill holes of down to 1 m (3.3 ft) with a spiral hammer drill.
