Abstract
A hand-held tool for driving a cutting or grinding disk includes a housing and a protection hood with a sleeve-shaped extension detachable connected to the housing. A receptacle is mounted on the housing for releaseably holding the sleeve-shaped extension. The receptacle is formed as a slotted sleeve so that it has a variable diameter. The diameter is changed by moving circumferential ends of the sleeve toward or away from one another. The displacement of the sleeve ends can be effected by a lever pivotly mounted on the ends.
