In a method of manufacturing tools having attached thereto cutting plates with a cutting edge coated with a hard cutting material, the cutting plates are first positioned on the cutting tool body in a desired position and fixed on the cutting tool body in that desired position by electric spot welding. Subsequently, the soldering material is applied to each cutting plate. Soldering of the cutting plates to the cutting tool body is performed at a temperature of 720.degree. C. to 850.degree. C. in a vacuum of 10.sup.-4 to 10.sup.-6 mbar. In a final step, the cutting tool body with the cutting plates soldered thereto is slowly cooled in the vacuum oven.
