An electric handheld power tool, including a data memory and a data interface signal-connected to the data memory, via which tool-related data may be read out from the data memory with the aid of a terminal, the data interface including a system antenna for wireless radio data transmission, and the electric handheld power tool including an amplifier antenna which is different from the system antenna, the amplifier antenna being magnetically coupled with the system antenna and preferably mounted on or in the direct vicinity of the system antenna.

Handheld power tool and amplifier antenna

A hand-held power tool, in particular a hammer drill or combination hammer, is disclosed. The power tool includes a tool housing which has a receiving recess designed to replaceably receive a storage battery or a power supply unit. The hand-held power tool further includes an electric drive motor having a cooling fan and a first vent portion which is located on the tool housing outside the receiving recess and through which a volume flow generated by the cooling fan can be guided. The tool housing has a second vent portion which is different from the first vent portion and which is located in the receiving recess and through which the volume flow generated by the cooling fan can be at least partially guided.

Handheld power tool, fanless power supply unit and tool system

A rechargeable tool battery (), in particular for supplying a hand-held power tool (), including a rechargeable tool battery housing (), inside which a secondary cell battery () having a nominal cell voltage (UN) is situated, the rechargeable tool battery () including a rechargeable battery DC-DC converter (), integrated into the rechargeable tool battery housing (), which is electrically connected to the secondary cell battery (), and is designed for raising the nominal cell voltage (UN) to a supply voltage (UV) which is tappable at a rechargeable tool battery terminal () of the rechargeable tool battery ().

Rechargeable tool battery, mains-operable hand-held power tool, and tool system

A pneumatically striking hand-held power tool is controlled by the following steps. An acceleration (a) along a striking axis () of the hand-held power tool () is detected. A driving power is reduced if the detected acceleration (a) is greater than a threshold value (A), the threshold value (A) being selected to be greater than maximum acceleration values (a, a) that occur on a workpiece during the striking operation of the hand-held power tool ().

Control method and hand-held power tool

An electrical hand-held power tool includes an assembly () vibrating along a vibration axis (A) during operation of the power tool, at least one, transversely projecting, vibration-decoupled pivotal side handle (), a manual switch () having an actuation element () arranged in the side handle () and switchingly connectable with at least one sensor switch () which is located in the assembly () in vicinity of the handle pivot point (G), by a switching rod () having a switching element () and being pivotally supported on the side handle at a switching pivot point (S) spaced from the handle pivot point (G) and from the vibration axis (A).

Percussion hand-held power tool with contactless manual switch located in side handle

An electrical hand-held tool includes an electric motor () having a rotor shaft () extending transverse to the tool percussion axis (A), a rotor sheet stack () supported on the rotor shaft, and a pinion () supported on the rotor shaft, a percussion mechanism () including an eccentric (), and a drive gear () engageable with the motor pinion () for driving the eccentric (), with the rotor sheet stack () being arranged, with respect to the percussion axis A, completely diametrically opposite the drive gear ().

Percussion electrical hand held tool

An electrical tool includes a housing having inlet () and outlet () openings, a brushless electric motor () and an inverted rectifier () both arranged in the housing () between inlet () and outlet () openings in an air stream () of an air volume (), and a link condensator () located in the housing () in the air stream (), with the inverted rectifier () being arranged, in the air flow direction, downstream of the link condensator () and upstream of the electric motor ().
