The disclosure relates to an electric tool, particularly a hand-held power tool, comprising a control unit which has control software with control parameters, and is provided for the purpose of controlling a drive unit. According to the disclosure, said electric tool comprises an interface unit that is provided to fundamentally update and/or modify the control software and/or the control parameters.

Electric tool

The invention relates to a hand-held power tool, especially a rotary hammer and/or chisel hammer. The hand-held power tool is provided with a vibration dampening unit having a first absorber mass unit with a first vibration dampening direction and at least one second absorber mass unit with a second vibration dampening direction. The hand-held power tool in particular has the first vibration dampening direction of the first absorber mass unit disposed as substantially parallel to the second vibration dampening direction of the second absorber mass unit.

Hand-held power tool

The invention relates to a wobble drive of a hand-held machine tool, particularly a drilling or chipping hammer, having a drive shaft, a wobble bearing disposed on the drive shaft, and a wobble plate supported on the wobble bearing. At least two wobble fingers having wobble finger axes being provided on the wobble plate. The invention provides that the axes of the wobble fingers form an angle different from 180&#xb0;.

Wobble drive of a hand-held power tool

A machine tool and a tool include an automatic balancing device, with a first balancing mass located such that it is movable relative to the shaft of the machine tool in all radial directions and in the circumferential direction, that may be started rotating via the rotation of the shaft, and that, during rotation, exerts a force on the shaft in the radial direction.
