Abstract

See full text

The invention discloses a portable tool having a housing with a gearhead, having a motor shaft which can be rotationally driven by a motor and which can be coupled via an eccentric coupling drive to a tool spindle for the drive thereof, wherein the tool spindle can be driven in a rotational oscillatory manner about the longitudinal axis thereof and is configured for accommodating a tool, wherein a motion-reversal drive is provided which is configured for converting an oscillating drive movement produced by the eccentric coupling drive into an oscillating output movement which has a direction of oscillation opposed to said drive movement. The motion-reversal drive is configured as an epicyclic gearing.
