摘要：
The present invention relates to a tool and a tool tip for chip removal, wherein the tool in operative position preferably rotates around its longitudinal centre axis. The tool tip (10") contains two hard metal grades, a tough, less wear resistant grade in the inner portion (40") and a more brittle, more wear resistant grade in the external portion (41"). The tool tip is made from two grades that have the same shrinkage. The inner portion (40") is entirely surrounded by the external portion (41") except for in the feed direction and the retraction direction. The tool tip has a thread (25) formed in the tougher hard metal such as to endure high tensions.
