Hydraulic Underground Roof Bolter KDH-3
The KDH-3 roof–bolting drill is designed for drilling anchor holes and for anchoring in rocks of varying hardness using a rotary method with the application of a water-based drilling fluid.
The depth of the anchor depends on the tool diameter and the method of anchoring. When installing Ø28 mm steel rock bolts, the maximum drilling depth is 3 m.m.
