A tool and a cutting insert for chip removing machining, such as milling, turning or the like. The cutting insert includes a chip-removing main edge, which is separated from a center of the cutting insert and from which a clearance surface extends toward a transition to an underside in the form of a connecting surface, in which an elongate engagement means, e.g., a ridge, is included, which is situated nearer the transition than the center of the cutting insert, and includes a flank having the purpose of transferring cutting forces in the direction transverse to the length extension of the ridge. The ridge is the only active engagement means of an imaginary triangle between the center of the cutting insert and opposite ends of the transition, besides which the flank has a cross section-wise convex shape. In such a way, the active edge of the cutting insert is located in a desired exact position in relation to the tool, even if the cutting insert is impaired by minor form defects.
