ABSTRACT:
The present disclosure relates to an oscillating cutting toolhead having an oscillating cutter comprising two blades which are prestressed radially inwardly, the blades bearing against opposite points of a spacer disposed therebetween, the device being characterized in that the spacer has a cross section of generally circular form with two opposed parallel, axially extending flattened portions, the spacer being axially non-displaceable yet rotatable about the longitudinal axis of the tool and arranged for limited oscillation relative to the cutter in the angular position in which the two flattened portions are parallel to the oscillating direction of the cutter, the spacer being operatively connected with a rotary dog guided in the toolhead for axial and rotatable displacement. The dog may be axially displaced and locked in a retracted position away from the spacer by insertion of a tool through an axial opening in the toolhead to facilitate cutter blade replacement.
