A compressor rotor blade () includes a rotor blade (), a platform () that adjoins the rotor blade () and blade footing () that adjoins the platform (). The rotor blade () is embodied so as to be massive, without an internal cooling system, and exhibits a leading and a trailing edge (), a suction and a compression side, as well as a blade tip (). The compressor rotor blade () is distinguished by virtue of the fact that the rotor blade () of the compressor rotor blade () exhibits a recess () on the trailing edge () of the blade tip ().
