Zusammenfassung:A quill is rotated in a spindle and carries a tool which is rotated with the quill about a common axis. The tool is held in a bore in the quill by a combination of a tool receiver, a drawbar and an attachment member which is shrunk fit to the tool. The overhang of the tool is greatly reduced and tilting takes place through the base of the attachment member rather than through edge loading of the tool in a bore.
