Abstract
A cutter head for a brushcutter has a base member with top and bottom base member parts and rotates about an axis of rotation in operation. The top base member part is fixed to the brushcutter shaft end. The bottom base member part is screwed by a screw element to the shaft end. A bearing element is arranged in the base member radially spaced to the axis of rotation. A cutting tool is secured by the bearing element to the base member between top and bottom base member parts. The bearing element is secured either to bottom or top base member part and arranged relative to the other one such that the bearing element is constructively unhindered to move relative to the other base member part at least circumferentially and such that the bottom base member part for mounting or demounting is rotatable relative to the top base member part.
