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.

Suction device

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.

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.

An electric power tool is disclosed. In an embodiment, the electric power tool includes a tool, a tool holder part and a main body with a plurality of rivets integrated with the main body. The rivets include rivet shafts of a cross section for producing a positive-locking rivet joint of the tool with the tool holder part, wherein the tool and the tool holder part have circular openings which are aligned with each other, and wherein the rivet shafts are positioned aligned with the openings on the main body and protrude through the aligned openings.

Component for establishing a form-locking riveted connection of a tool

A saw blade or a cut-off wheel for an oscillating tool machine includes a base body, wherein the base body has a cutting area and the cutting area is coated with a granulated carbide, wherein the base body is formed in one piece and includes martensitic stainless steel and/or martensitic steel.

The invention discloses a tool for grinding and polishing, comprising a drive motor, which has a given machine power (rated input power) and by which a work spindle can be driven about its longitudinal axis in rotatingly oscillating fashion, and further comprising a tool-mounting fixture on the work spindle intended to receive a tool that has a working surface for grinding and polishing operations. The quotient of the working surface (in square millimeters) and the rated power input (in Watts) is at least 35 mm/W, while the quotient of the working surface and the deadweight (in grams, without the tool) is at least 5.5 mm/g.

Grinding or polishing tool for an oscillating drive

A tool for parting, in particular for sawing, includes a carrier blade that has a toothing portion with a finite, geometrically determined toothing, and a receiver for fixing the carrier blade to a tool spindle of a power tool. The tool spindle can be driven in oscillation about its longitudinal axis. The toothing is disposed at a distance from the receiver and is configured to be advanced perpendicularly in relation to the longitudinal axis, such that the toothing is realized in a non-uniform manner along the toothing portion. The toothing portion has a middle region and end regions that adjoin the middle region and that are provided with strengthened corner teeth.
