The device enables the user to use rotational force instead of a direct force to remove the bit.

Abstract: The invention concerns an apparatus and a method for mechanically joining metal sheets, profiles and/or multi-sheet joints lying on top of each other, wherein joining tools are moved by power means towards the parts to be joined and a joint is made between the parts to be joined by the force effect of the joining tools. To make the joining tools easier to handle and widen the range of application for joints, it is proposed to reduce the reaction forces of the joining process by the fact that one joining tool applies the joining force to the joint at an exciting frequency which is above the characteristic frequency of the opposite joining tool, and the mounting of at least one joining tool is isolated from vibrations. The vibration isolation can also be arranged exclusively or in addition in the excited joining tool or the parts to be joined.
