Abstract
A gear head for a manually guided power implement is provided. Part of the tool shaft, which receives a rotatable cutting tool, is embodied as a cylindrical splined shaft having grooves for the positive transmission of torque to the cutting tool. An abutment plate is disposed on the tool shaft and has an abutment surface that extends essentially perpendicular to the longitudinal axis of the tool shaft. A centering cylinder extends through a circular central opening of the cutting tool and has inwardly directed longitudinal ribs that engage in the grooves of these splined shaft. A free end of the centering cylinder is provided with a beveled portion that extends from an outer contour of the cylinder to into the grooves.
