Abstract

Walzenförmiger Schneidkörper, insbesondere für eine Schrämmaschine oder Straßenfräse, mit zumindest einem auf der Mantelfläche des Schneidkörpers angeordneten Grundkörper, mit dem jeweils ein Meißelhalter oder dergleichen durch eine Sicherung fixiert auswechselbar verbunden ist, die durch eine sich durch den Grundkörper erstreckende Bohrung und einen darin angeordneten Sicherungsbolzen ausgebildet ist, der eine zugeordnete Ausnehmung des Meißelhalters zumindest bereichsweise durch- oder hintergreift, wobei der Sicherungsbolzen am Grundkörper gewindelos klemmend oder rastend gehalten ist.
