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.
