A face mill and a replaceable milling insert are disclosed. The front side of the milling insert is tilted at a clearance angle (epsilon) in relation to the reference plane (RP). The cutting edge of the milling insert extends between two end points, which move in circular paths of different radii. The cutting edge forms a negative radial angle (delta) with an imaginary radial line (A) that extends from the center axis (C1) of the basic body and intersects the first end point of the cutting edge. The front side and chip surface of the milling insert mutually form a nominal angle (beta) that amounts to at most 83° . The cutting edge is straight and in the entire length thereof situated in the reference plane (RP), the negative radial angle (delta) thereof amounting to at least 70°.
