摘要： The present invention relates to a threading tool, a threading insert, and a method of forming a thread. The threading insert (21) comprises a cutting edge (23). The insert comprises an insert supporting surface (25) and a clamping surface (27') for clamping the 5 insert relative to a toolholder (29) such that the insert supporting surface supports the insert against an abutment surface (31) of the toolholder. At least one layer (33) of PCBN forms a face (35) of the insert. The cutting edge (23) extends at least partially around a periphery of the insert and is formed in the PCBN layer.
