<p>The present invention relates to a tool, a tool body and a tool tip for chip removing machining, wherein the tool in operative position preferably rotates about its longitudinal center axis. The tool comprises a tool body (12), a tool tip (10) and a pull rod, said tool body having a front surface and the tool tip having an end surface provided to detachably face each other. The body has a shank portion (40). The tool tip consists of injection molded cemented carbide and comprises a central blind hole (14) that cooperates with the means for retention, and at least one cutting edge (19). The blind hole and the cutting edge are integral with the tool tip (10). The cutting edge extends from the tool periphery to the area of the axis (22) of rotation of the tool. The front surface (24) and the end surface (16) comprise cooperating projections (30) and recesses (26), which are provided to substantially alone transfer cutting forces directed towards the shank portion appearing during machining. The cooperating projections (30) and recesses (26) are substantially X-shaped.</p> |
