A cutting tool assembly wherein a cutting head is releasably retained by a tool holder by means of interacting coupling members, with one of the coupling members being inserted into a cavity of the other coupling member, with radially extending abutment wings of said one coupling member passing respectively between successive support wings of the other coupling member, rotation of the one coupling member resulting in the abutment wings abutting and resting on the support wings, thereby effecting a retaining coupling between said cutting head and said tool holder. |
