    Abstract: A metal cutting insert that is primarily intended for turning operations includes an upper surface, a lower surface substantially parallel with said upper surface, and at least three side surfaces extending between said upper and lower surfaces. A transition between two adjacent side surfaces forms a rounded nose radius surface at a cutting insert corner. The cutting insert includes a peripheral land bridging the upper and side surfaces at least at the corner portion at a chamfer angle. An intersection of the land and the nose radius surface forms a nose cutting edge. The nose cutting edge is defined by at least one radius. The cuffing corner includes at least one curved wiper edge. The chamfer angle in a cross-section at the nose cutting edge is larger than the chamfer angle in a cross-section a distance away from the nose cutting edge.

    Abstract: The present invention relates to a threading tool, a threading insert, and a method of forming a thread. The threading insert includes a cutting edge. The insert includes an insert supporting surface and a clamping surface for clamping the insert relative to a toolholder such that the insert supporting surface supports the insert against an abutment surface of the toolholder. At least one layer of PCBN forms a face of the insert. The cutting edge extends at least partially around a periphery of the insert and is formed in the PCBN layer.
