Sandvik DL421 is an electro-hydraulic, longhole drill rig engineered for large-scale production drilling in underground mines. This versatile rig has been designed for vertical and inclined rings and fans, as well as parallel long production holes and long single holes with a diameter of 64 to 115 millimeters, and a depth of up to 54 meters. The 360° drilling module rotation, wide boom swing and tilt angles make the unit suitable for most mining applications.
