The invention concerns a milling insert (4) and a milling tool (1) for the milling of a slot in a workpiece (2). The milling insert comprises an under side (11), an opposite upper side (12) that forms a chip surface and is parallel to an extension plane, and an edge side (13) between the upper side and the under side. A cutting edge, which extends between the edge side and the chip surface, comprises a primary main cutting edge (15), a secondary main cutting edge (16), and an end cutting edge (17). The end cutting edge (17) connects the primary main cutting edge and the secondary main cutting edge and borders on the primary main cutting edge at a primary transition point (15') and on the secondary main cutting edge at a secondary transition point (16'). A normal to the extension plane of the chip surface forms an acute clearance angle with the edge side along the cutting edge. The end cutting edge is curved from the primary transition point to the secondary transition point. |
