In this project, the drill head to be analysed is the Sandvik Coromant CoroDrill® 880 (Figure 2). This tool is commonly used in industry to drill holes in metallic bodies with a high accuracy and small hole tolerances (Coromant, 2018). This drill has two replaceable inserts; one located partly eccentric of
Sandvik DL311-7 is an el ectro-hydraulic longhole drilling rig for small and medium scale production drilling in underground mines. The rig is capable of drilling 64-89 mm holes up to 38 meters. The rig has been designed for vertical and inclined plane rings and fans and also for parallel long pro- duction holes as well as for long single holes.
