Abstract

A manually guided electrical tool which is driven by a drive motor. The tool includes a device for metering and mixing at least two substances and for the feeding of the intermixed substances to a treatment place. The device includes: cartridges which contain the substances to be intermixed, receptacle pockets for receiving the cartridges, an extruding means associated with each cartridge for extruding the substances; a mixer for mixing the extruded substance which has an outlet through which the intermixed substances are fed, a feed duct connected to a each cartridge for transporting the extruded substances to the mixer, a gear unit driven by the drive motor, a drive element driven by the gear unit for activating the extruding means and the mixer; and a gear housing for housing the gear unit which is attached to the drive motor.
