Abstract

Die Erfindung betrifft ein Meißelwerkzeug mit einem Meißelkopf (1), Meißelschaft (2) und Einsteckende (3), die entlang einer Meißellängsachse (4) hintereinander angeordnet sind, wobei der Meißelkopf (1) an seinem freien axialen Ende eine Meißelschneide (5) aufweist. Es wird vorgeschlagen, dass der Meißelkopf (1) axial versetzt zu der Meißelschneide (5) mindestens eine Ersatzschneide (7) ausbildet, die durch den auf den Werkzeugverschleiß zurückgehenden Abtrag von Werkzeugmaterial freigelegt wird und dann zumindest einen Teil der Meißelschneide (5) ersetzt.
