Abstract
A clamping device has a main body with a bore that extends from a back to a front end thereof. The bore has a fastening area proximate the back end, a front-end axial abutment surface and a central axial abutment surface. A centering sleeve is disposed in the bore and extends axially between a centering sleeve first and second axial end. A guide sleeve is disposed in the bore and partially in the centering sleeve. The guide sleeve extends axially between a guide sleeve first and second axial end. A locking member is removably disposed in the fastening area, has a tapered abutment surface and faces the front end. The centering sleeve is axially retained by and between the tapered abutment surface and the central axial abutment surface. The guide sleeve is axially retained by the tapered abutment surface and the central axial abutment surface.
