Abstract: A vibration damper for a drill tube of a hole machining apparatus includes a closed loop bi-directional adjustment mechanism, which operates from a single side of the damper. The closed loop mechanism ensures that the position of the clamping sleeve has a one-to-one relationship with the adjustment mechanism, which enables controlled adjustment of the clamping force to be performed. Locating the adjustment mechanism at one side of the clamping sleeve facilitates re-tooling, e.g. replacing the clamping sleeve if a larger diameter drill tube is to be used.
