    摘要： A suction device for a handheld power tool that is adapted to be driven in oscillation and that is equipped with a gearbox extension housing for mounting of the suction device. The suction device having a body mounted on the gearbox extension housing of the handheld power tool via a mounting section and an air duct formed in the body, the air duct being delimited at one end by an air inlet and at an other end by an air outlet on which a suction apparatus or a dust exhauster is adapted to be detachably mounted. The mounting section of the body is formed essentially as a hollow cylinder and extends between a first plane and a second plane, which are substantially parallel.

    摘要： A tool attachment, in particular hole saw, for a power tool having a driving axle that is drivable in oscillation. The tool attachment including 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 has teeth, with the work area being at least partially circular in design and adjoining a hollow, cylindrical base. Openings are formed in the base, the openings constituting at least 60%, at least 80%, or at least 90% of the area of the base.

    摘要： A suction device for a hole saw of a hand-held power tool oscillatingly driven about an oscillation axis. A substantially disk-shaped base body has a first side that faces the hand-held power tool and a second side that faces the hole saw. A fastening section detachably fastens the suction device to an oscillatingly driven hand-held power tool; and a connecting piece connects the suction device to a suction apparatus.
