<p>The present invention relates to a rotatable tool having a replaceable tip (3), the tool also comprising a tool body (1) having a cutting seat (9), in which the tip (3) is intended to be received that the tool body (1) has helicoidal or straight chip channels (7), that the tip (3) has members (18) for chip removing machining, and that the cutting seat (9) and the replaceable tip (3) have mutually co-operating support surfaces (10, 12, 20, 21) extending both in the longitudinal direction of the tool and transverse to the longitudinal direction of the tool. The invention also relates to a tip separately. Characteristic of the tool according to the present invention is that the cutting seat (9) and the replaceable tip (3) have mutually co-operating guide surfaces (15, 22), which are rotationally symmetrical in respect of a longitudinal centre axis (2) of the tool, as well as members (12, 17, 21) for clamping the replaceable tip (3), when the same is assembled in the cutting seat (9), in the axial direction of the tool, that a locking screw (17) is received in the tool body (1), and that the locking screw (17) brings the replaceable tip (3) to co-operate with the members for clamping the replaceable tip (3) in the axial direction of the tool.</p> |
