Abstract: A cutting insert and a shoulder milling tool are disclosed. The cutting insert includes a surface-wiping secondary cutting edge inclined in relation to a median plane of the cutting insert such that a distance to the median plane decreases in a direction toward a corner cutting edge. The corner cutting edge, as seen in a side view along the median plane and towards a main cutting edge, has a concave curve.

Abstract: A cutting insert and a shoulder milling tool are disclosed. The cutting insert includes a surface-wiping secondary cutting edge inclined in relation to a median plane of the cutting insert, such that a distance to the median plane decreases in a direction toward a corner cutting edge. A circumferential surface includes a clearance surface extending along a main cutting edge. The clearance surface along the main cutting edge extends at an acute angle to the median plane, such that the clearance surface forms a negative nominal clearance angle, and wherein the circumferential surface includes first and second abutment surfaces configured for abutment against axial and/or radial support surfaces of the milling tool, the abutment surfaces extending along at least part of the main cutting edge and the surface-wiping secondary cutting edge.

Abstract: A cutting insert for a shoulder milling tool has a trigonal shape and includes a first surface, a second surface, and a circumferential surface extending between the first surface and the second surface. The circumferential surface includes a countersunk circumferential waist portion. The circumferential surface has a first and a second clearance surface extending along a first and a second main cutting edge. Each of the first and second clearance surfaces forma a negative nominal clearance angle. Each of the first and second main cutting edges is arranged inside the countersunk circumferential waist portion, as seen in the view towards the first and second surfaces, respectively.
