Fragmenting devices for shredding paper and breaking compact discs, comprising a compact disc cutting tool set configured at a side of and linked up by means of a connecting gear to a cutting tool set of a conventional paper shredder. The compact disc cutting tool set is constructed to include two juxtapositioned cylindrical rotary cutters, and pressed grains are defined on surfaces of the two rotary cutters. A compact disc is inserted between the two rotary cutters through a compact disc insertion opening defined in a top surface of a top cover, and thereupon the pressed grains on the surface of the cutting tools mash and break up the compact disc.
