A method of manufacturing a composite chip-removing tool which includes a tool body of a material which is in its molten state above a predetermined melting temperature, and at least one tipping element secured to the tool body, comprises positioning the tipping element on a model of the tool body that consists of a material that melts at a temperature considerably lower than the predetermined melting temperature, in a position relative to the model which the tipping element is to assume relative to the body, and simultaneously forming the tool body and a durable mechanical connection of the tipping element to the tool body in a precision casting operation involving replacement of the material of the model with the material of the tool body in its molten state. The model may be produced prior to or simultaneously with the positioning of the tipping element on the model. For establishing the durable connection, the tipping element is provided prior to its positioning on the model with at least one aperture which preferably has at least one cross-sectional enlargement and which is subsequently filled with the material of the tool body during the formation of the tool body, so that the material of the tool body which has penetrated into the aperture establishes a durable connection of the tipping element to the tool body. The model has at least one projection received in the aperture of the tipping element.
