The disclosure relates to a power tool separation device, in particular a hand-held power tool separation device, comprising at least one cutting unit which comprises at least two interconnected cutter support elements. At least two cutter support elements are interconnected by means of at least one connecting element of the cutting unit, and the connecting element is essentially flush with at least one outer surface of the at least two cutter support elements.

Power tool separation device

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

Hand-held power tool having a tool receiver

A power tool system includes at least one power tool which has at least one workpiece support unit that is configured to support a workpiece during machining, and also includes at least one machining tool device which extends through a workpiece support surface of the workpiece support unit in at least one operating state. The machining tool device includes at least one cutting strand that is configured to be driven in circulation. A ratio of a maximum height of the workpiece support unit to a maximum cutting depth of the machining tool device is less than 4.1.

Power tool system

A cutting strand segment for a cutting strand of a machine tool separating device includes at least one blade carrier element, at least one blade element arranged on the blade carrier element, and at least one cutting depth limiting element arranged on the blade carrier element which is configured to limit a maximum cutting depth of the blade element to a value that is less than 0.5 mm.

Cutting strand segment

A method for producing a cutting unit segment of a cutting unit of a machine tool separating device, includes at least one cutter support element and at least one cutter element. In at least one step, the cutter element is molded on the cutter support element by a drawing process in an at least partially staggered manner relative to an outer surface of the cutter support element.

Method for producing at least one cutting unit segment of a cutting unit of a machine tool separating device

A machine tool separating device, in particular on a handheld machine tool separating device, includes at least one cutting strand and at least one guide unit, which form a self-contained system. The guide unit comprises at least one main guide unit element and/or at least one cutting strand holding unit, wherein at least the main guide unit element and/or the cutting strand holding unit has at least two guide surfaces, which have different alignments in relation to one another and which, when mounted, are provided to guide the cutting strand.

Machine tool separating device

A power cutting tool includes at least one cutting strand and at least one guide unit configured to guide the cutting strand. The power cutting tool further includes at least one cutting strand contact guard unit which has at least one cutting strand contact guard element. The at least one cutting strand contact guard element is movably mounted on the guide unit and is configured to at least substantially prevent, in at least one operating position of the cutting strand contact guard element, contact between the cutting strand and a user of the power cutting tool.

Power cutting tool having a guard unit

A separating device for a machine tool includes at least one cutting strand and at least one guide unit configured to guide the cutting strand. The guide unit forms a closed system together with the cutting strand. The separating device further includes at least one cutting strand tensioning unit that is positioned on the guide unit, and that is configured to compensate for at least one of play and tolerance in the cutting strand.

Separating device for a machine tool

A machine tool separating device, in particular a manual machine tool separating device, includes at least one cutting train that comprises at least one cutter-support element and at least one connecting element that is integrally formed with the cutter-support element. The cutter-support element has at least one transverse securing element that is configured to secure the cutter-support element against a transverse movement relative to another cutter-support element of the cutting train to the greatest extent possible in the assembled state.

A power cutting tool includes at least one cutting strand, and at least one guide unit that is configured to guide the cutting strand. The power cutting tool further includes at least one coding unit which has at least one coding element that is configured to encode at least one coupling interface of the guide unit.

Power cutting tool

A tool coupling device for a receptacle of a machine tool separating device formed as a closed system includes at least one cutting strand tensioning unit that has at least one tensioning element. The tool coupling device also includes at least one operating unit that includes at least one operating element. The cutting strand tensioning unit includes at least one gear unit that is configured to move the tensioning element as a result of an actuation of the operating element of the operating unit.

Tool coupling device

A closure device, in particular a tool-holder closure device, includes at least one movably mounted closure element and at least one securing unit. The securing unit includes at least one movably mounted securing element configured to secure the closure element in at least one position thereof. The closure device further includes at least one stop unit which has at least one stop element. The stop element, depending on at least one position of the closure element, is configured to stop the securing element at least largely against a movement relative to the closure element.

Closure device

A tool coupling device is configured to hold a machine tool cutting device. In particular, the tool coupling device is configured to hold a machine tool cutting device configured as a closed system, having at least one cutting train clamping unit for generating a cutting train clamping force and having at least one tool-holding unit comprising at least one movably mounted tool-holder element. The tool coupling device includes at least one movement-coupling unit by which the tool-holder element can be coupled with a clamping element for a movement of the clamping element of the cutting train clamping unit.

The invention relates to a hand-held machine tool, in particular a hammer drill and/or chipping hammer. The tool according to the invention has a transmission device with a drive bearing that has at least one torque-transmitting means with a transmitting contour for transmitting a torque onto the drive bearing. According to the invention, the transmitting contour of the torque-transmitting means is produced by axial machining and/or a stamping and/or planning process.
