摘要

The broaching tool (1) has profiled inner surfaces, and multiple broaching tool inserts (6) arranged axially symmetric on a tool base body (7). The tool base body is formed by a hollow element i.e. hollow shaft. The hollow element comprises a reinforcement and/or a cushioning element in an inner side. The reinforcement is formed by bracing of variable reinforcement components in a hollow space of the hollow element in the base body. The cushioning element is formed by an arrangement of cellular structures i.e. metal foam.
