A cutter insert for disc-milling cutters, in particular, for milling crankshafts. The insert has upper and lower surfaces and circumferential lateral surfaces, which connect the upper and lower surfaces to one another. The insert includes raised swellings and/or projections on the upper surface, at least in the region of two corners, which preferably extend over the entire length of one side of the cutter insert, so that, in a view perpendicularly toward a cutting face formed by at least one of the lateral surfaces, the edge which defines the transition from the upper surface to the cutting face, has a portion projecting relative to the central edge section in the region of each of the two ends of this edge.
A cutter insert for a disc-milling cutter, comprising upper and lower surfaces joined by peripheral side surfaces, the side surfaces intersecting one another to form corners, the upper surface including a center portion and two raised projections, the projections extending along an upper portion of two opposite ones of the peripheral side surfaces, each projection extending the complete length of the respective side surface from one corner to an adjacent corner, another of the side surfaces defining a cutting face, wherein a transition edge defined between the upper surface and the cutting face includes a central portion and two raised edges disposed at opposite ends of the transition edge and defined by respective ones of the projections.
A cutter segment adapted to be mounted on a disc-milling cutter, the cutter segment including a body curved about an axis arranged to coincide with an axis of rotation of the disc, the body including a seat for accommodating a cutter insert, the seat including a radially outwardly facing insert support surface extending from an axially facing end face of the body, the support surface inclined at an acute angle relative to the axis, wherein an end of the support surface spaced remotely from the end face is located closer to the axis than is an end of the support surface situated at the end face.
