Abstract
A rotary chip-removing tool includes a rotary tool body and a tool tip fastened on a front end thereof. The tool tip is formed of an injection molded body which has an integral cutting edge at its front end, and a coupling structure at its rear end. The coupling structure can be in the form of a threaded hole, or a rearward projection, for coupling the tool tip against the tool body. The tool tip is formed of first and second materials. The first material forms at least part of the cutting edge, and the second material forms the coupling structure. The first material is more brittle than the second material, and the second material is tougher than the first material.
