Abstract: A cutting tool, such as a saw blade, has a carrier forming at least one cylindrical receptacle and at least one abutment jaw for a cutting insert. The cutting insert includes a cylindrical main cutting body and a cutting edge protruding radially therefrom, which on the back of the cutting edge has at least one abutment for the abutment jaw. The cutting insert can be inserted into the receptacle transversely to the cutting direction and, in the inserted position, can be rotated between an inserted position and a cutting position. The cutting insert is secured in the cutting position using an anti-rotation lock and is inserted into the cylindrical receptacle in the manner of a bayonet connection. Despite simple production and mounting conditions, the cutting tool ensures adequate stability and strength of interchangeable cutting inserts on the carrier such that thin-cut applications, such as carrier thicknesses of under 6 mm.
