A tool attachment for a power tool having a driving axle that is drivable in oscillation, the tool attachment comprising:
- a connecting device with which the tool attachment is attachable to the power tool such that the driving axle thereof and a tool axis essentially coincide;
- a work area having teeth, the work area being at least partially circular in design and adjoining a hollow, cylindrical base;
- and
- openings formed in the base, the openings constituting at least 60% of the area of the base,
- wherein the openings are spaced apart from the teeth, such that in a circumferential direction around the base, none of the openings overlap with the teeth, and
- wherein the openings are formed as circular areas and are arranged in rows, each of the rows extending around the base in the circumferential direction.
