A supply of cutting wire is wound on the wire cylinder or, on a reel rotatably fixed to the wire cylinder. A length of the wire extends out of the housing to act as a cutting tool when the housing rotates. A sleeve member is axially movable in the housing and has helical coupling piece which are coupled to helical piece in the cylinder. Axial movement of the sleeve thus causes relative rotation …
