Abstract: The present disclosure relates to a trimming and/or fin cutting tool for removing ridges, burrs and casting seams of the kind having interchangeable cutting edges, preferably made of hard metal, in which one or more cutting lines of the tool is or are formed by a number of cutting plates (1) detachably mounted on the vertical side (3) of a tool body (2). The tool enables the rational use of the detachable cutting plates and is characterized mainly in that the cutting plates are reversible and are attached to the tool body (2) in a plane directed in the working direction of the tool, the cutting plates having spaces between them to form gaps (6) for the passage of chips. Preferably, the cutting plates along the or each cutting line are attached to the tool body (2) in rows at different heights relative to a base, the separate effective cutting edges of the cutting plates (1) along a common cutting line being arranged to overlap each other.
