Abstract

A tool for cutting and shaping a lower edge of a profiled unfinished concrete roofing tile manufactured using the extrusion method, having a tool holder, a cutting insert provided with a cutting edge, and a template. To create a tool which has a significantly increased useful life for cutting and shaping an unfinished concrete roofing tile, the invention teaches that the tool holder and the template are realized in one piece in the form of a support body with a recess for the adhesive and positive connection of the cutting insert, that the cutting insert is made of tungsten carbide and is fastened in the recess by means of adhesive, and that the cutting insert is in contact by means of its upper edge with at least one projection of the support body.
