Abstract

The invention relates to an electric hand tool comprising a rotatably driven circular tool (22) and a protective cover (28, 32) mounted on the electric hand tool and rotatable about an axis (24) which is parallel or coaxial to a shaft (34) to a limited or partial extent. In a rest position of the protective cover (28, 32), a tool (22) is completely covered. A restoring device exerts a restoring force on the protective cover (28, 32) in the direction of the rest position and the protective cover (28, 32) comprises a stationary part (28). According to the invention, the protective cover (28, 32) comprises two (32a, 32b) or more movable parts that interact with the stationary part (28) to completely cover the tool (22) in the rest position.
