Abstract
A tool system is provided that has a stamp or punch adapter including eccentrically positioned stamp receptacles. This system permits a simple exchange of tool inserts in the stamp adapter. These tool inserts are also usable in another tool system. The system also permits combining the stamp adapter with a stamp shaft, which can also be used in another tool system. These features permit stamping (and punching) with minimal tooling and retooling efforts.
