Abstract: A hand-held grinding machine includes a disc tool having a machining face for machining a workpiece; a motor for driving a holder holding the tool arranged in a machine housing; a port for removing dust during machining; and an energy-storage-device interface for detachably connecting, using a connection interface, an energy storage device for supplying electrical energy to the grinding machine that includes an energy-storage-device housing extending along an energy-storage-device longitudinal central plane; and a handle for grasping and guiding the grinding machine forwards along the workpiece in a working direction parallel to a machine longitudinal central plane of the machine housing extending transversely to the machining face.

Abstract: An electric tool, in particular a sawing device, including a tool, in particular a saw blade, for machining a workpiece. The electric tool has an operator-control device via which there can be input a parameter value of at least one parameter relating to an operation of the tool, for example a cutting depth and/or a cutting angle. The operator-control device has a setting element, which is configured as a turn/push switch, for inputting the parameter value, and a display unit for displaying the at least one parameter value.
