The invention relates to a machine tool with a tool receiving device that is movable around an output shaft. The tool receiving device is designed to hold a tool device on the machine tool such that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region and a holding device. To transmit a driving force to the tool device, the torque transmission region has at least two output area regions arranged at a distance from said output shaft, with each having a multiplicity of surface points. The tangent planes to said surface points are inclined in regard to an axial plane including said output shaft. The tangent planes are inclined in regard to a radial plane extending perpendicularly to the output shaft. The machine tool thus transmits the output torque to the tool device via the tool receiving device.

Power tool

The invention relates to a tool device which is suitable for use with a machine tool, in particular a hand guided machine tool, having a driving device moving, in particular in an oscillating manner, around a driving axis. The tool device has an attachment device which allows it to be fastened on a machine tool such that its driving axis and an axis of rotation of the tool substantially coincide. The attachment device, for absorbing the driving force, has at least two driving area regions, which are spaced apart from said tool axis of rotation and each has a plurality of surface points. The tangent planes to said surface-area points are inclined in regard to an axial plane, which encloses the tool axis of rotation. Furthermore, said tangent planes are inclined regard to a radial plane which extends perpendicularly to the tool axis of rotation. This means that the torque introduced into the tool device by the machine tool, via the driving device, is reliably absorbed.

Tool 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.

Suction device

An oscillatingly driven machine tool having a housing in which a motor with a motor shaft is received, on which an eccentric element is accommodated, with a spindle head, with a tool spindle that is rotatably mounted about its longitudinal axis in the spindle head, on which a coupling element is non-rotatably received, which cooperates with the eccentric element for generating a movement of the tool spindle which oscillates about its longitudinal axis such that, in addition to the oscillating movement, a differing, superimposed movement is introduced into the coupling element.

Machine tool driven in an oscillating manner

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.

Tool attachment for a power tool

An oscillation drive with a drive and with an eccentric coupling drive for converting a rotary motion of the drive into an oscillating rotary motion of a tool spindle about its longitudinal axis is disclosed, wherein the eccentric coupling drive has an eccentric with a first eccentricity that is driven by the drive and that works together with a coupling element that is coupled to the tool spindle in order to convert the motion of the eccentric into an oscillating rotary motion of the tool spindle, wherein the eccentric is coupled to an additional eccentric with a second eccentricity so that the eccentricities are superimposed, wherein the relative position between the eccentric and the additional eccentric is adjustable to at least two different positions in order to change the amplitude of the oscillating motions of the tool spindle.

Oscillation drive with adjustable oscillation angle

The invention relates to a machine tool, in particular a hand held machine tool, which has a tool receiving device that is movable, in particular in an oscillating manner, around an output shaft. The tool receiving device is designed to hold a tool device on the machine tool in such a manner that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region and a holding device. In order to transmit a driving force to the tool device, the torque transmission region has at least two output area regions that are arranged at a distance from said output shaft and each have a multiplicity of surface points. Here, the tangent planes to said surface points are inclined in regard to an axial plane which includes said output shaft. Furthermore, the tangent planes are inclined in regard to a radial plane which extends perpendicularly to the output shaft. In this way, the output torque is transmitted reliably to the tool device by the machine tool via the tool receiving device.

The invention relates to a machine tool, in particular a hand held machine tool, which has a tool-accommodating device which can be moved, in particular in oscillating fashion, about a drive axis, in order to retain a tool device on the machine tool. The tool-accommodating device has at least one clamping device, at least one retaining device and at least one locking device. The retaining device can be moved from at least one first, open position into at least one second, closed position. It is also the case that the retaining device can be forced by a clamping force, by way of the clamping device, preferably in the closing direction from said first, open position in the direction of said second, closed position. The locking device can be moved between at least one first, locking position and at least one second, unlocking position. It is possible here for said locking device to block movement of the retaining device in at least one locking position. A force applied to the locking device directly or indirectly by the tool device moves said locking device from one of said locking positions into one of said unlocking positions. This allows the tool device to be inserted particularly quickly and straightforwardly into the machine tool.
