Embodiments herein relate to a rotary attachment of a power driven garden tool, which rotary attachment (100) comprises a core member (110) having a cylindrical configuration and an envelope surface (111). The core member (110) is arranged to be rotatably coupled to a rotary attachment receiving portion of the power driven garden tool, so as to be rotatable about a central longitudinal axis of rotation (112). The rotary attachment also comprises a working tool (120), attached to the core member (110) so as to rotate therewith. The rotary attachment is characterized in that the core member (110) comprises at least one air gap providing element (115) extending between two axially spaced apart positions along the envelope surface (111) of the core member (110).
