  An der Oberfläche gehärteter Schlagkolben für Schlagwerkzeuge. 



   Die Erfindung betrifft einen an der Oberfläche gehärteten Schlagkolben, insbesondere für   Druclduftschlagwerkzeuge   mit in dem Aufschlagende angeordnetem Einsatzstück. 



   Dieses   Einsatzstück   ist gemäss der Erfindung als zylindrisches, hoch gehärtetes Kernstück ausgebildet, das in einem aus weichem Stahl bestehenden Sitz eingebettet ist. Hiedurch wird erreicht, dass der Kolben beim Betrieb nicht splittert, und verhindert, dass das Kernstück in den Kolbenkörper hineingeschlagen wird. 



   Die Erfindung ist in der Zeichnung beispielsweise dargestellt, wobei das im Kolben   I,   eingesetzte Kernstück mit a bezeichnet ist.

  Impact piston with hardened surface for striking tools.



   The invention relates to an impact piston with hardened surface, in particular for compressed air impact tools with an insert arranged in the impact end.



   According to the invention, this insert piece is designed as a cylindrical, highly hardened core piece which is embedded in a seat made of soft steel. This ensures that the piston does not splinter during operation and prevents the core piece from being knocked into the piston body.



   The invention is shown in the drawing, for example, the core piece inserted in piston I being denoted by a.
