A tool receptacle for a hand-held power tool, in particular for a demolition hammer or chisel hammer, includes—a receptacle element for receiving a tool, and a locking element which for locking the tool in the tool receptacle is mounted so as to be eccentric and rotatable on the receptacle element, wherein the locking element with the aid of rotating the latter about the receptacle element is capable of being moved from an unlocked state in which the tool is retrievable from the receptacle element to a locked state in which the locking element encompasses the tool in a form-fitting manner, and vice versa.

Tool receptacle and hand-held power tool

A flat chisel () having a longitudinal axis (), a shank () and a blade-shaped working section (). The shank () has a striking surface () perpendicular to the longitudinal axis (). The working section () has a cutting edge () that is crosswise to the longitudinal axis (). The cutting edge () is configured so as to be saddle-shaped.

Handle for tools

A combined electrical hand tool having an operating mode selection switch ( ) with additional special functions that can be switched using a displaceable linkage ( ) that can be displaced by the operating mode selection switch arranged between a lubricated assembly ( ) having a coupling ( ) and the external housing ( ), wherein in at least two separate lubricant-tight assemblies ( ) at least one switchable coupling ( ) is present, which can be moved over an outwardly extending actuator ( ) that is mounted lubricant-tight.
