This demo shows David drilling into a block of concrete with a drill hammer. The built in VSA enhance Davids mechanical robustness against external impacts. This allows him to handle the impacts due to the drill hammering with relative ease. The drilling task shown requires both, precise positioning of the tool center point and vibration damping.
