Abstract: A material collection device for a hand-held power tool includes a material collection container for collecting material removed during operation of the hand-held power tool. At least one opening of the material collection container is for feeding the material into the material collection container and is arranged in an opening plane. At least one mounting unit is for mounting the material collection container on the hand-held power tool. The at least one mounting unit includes a channel element for connection to an ejection port of the hand-held power tool. A channel longitudinal axis of the channel element is arranged transversely to the opening plane of the material collection container in at least one section plane running perpendicularly to the opening plane.

Abstract: In a method for identifying a deflection or a breakdown of a machine tool, in particular a hand-held machine tool, with an oscillating output movement, in particular a linearly oscillating output movement, at least one physical characteristic of the machine tool, in particular of a motor, a powertrain component, and/or a machining tool of the machine tool, is detected continuously or periodically by means of a detection unit. The method further includes detecting a deflection or a breakdown of the machine tool with an analysis unit on the basis of at least two values, which are identified at different times, of the characteristic of the machine tool, wherein each of the at least two values of the characteristic are associated with at least one respective substantially identical value of a discrete position characteristic of the oscillating output movement, in particular the linearly oscillating output movement, of the machine tool.

Abstract: A machine tool device includes at least one motorized machining tool, at least one, particularly capacitive, sensor unit, configured to detect at least one foreign body in at least one detection area around the machining tool, and at least one closed-loop and/or open-loop control unit configured to trigger at least one action depending on at least one signal from the sensor unit. The sensor unit includes at least one antenna configured to emit at least one electrical and/or magnetic field, which defines the at least one detection area, and/or to detect the at least one foreign body depending on at least one change in the at least one electrical and/or magnetic field.

Abstract: A machine tool device includes at least one motor-driven machining tool; at least one sensor unit, in particular a capacitive sensor unit, which is configured to detect at least one foreign body in at least one detection area around the machining tool; and at least one open-loop and/or closed-loop control unit configured to trigger at least one action in accordance with at least one signal from the sensor unit. The sensor unit includes at least one antenna configured to emit at least one electric and/or magnetic field defining the at least one detection area and/or to detect the at least one foreign body in accordance with at least one change in at least one electric and/or magnetic field.

Abstract: A hand-held sanding machine includes at least one sanding device for receiving or configuring a sanding apparatus. The sanding device includes at least one fan for conveying away material subtracted in a sanding procedure, at least one drive device for driving the sanding device, and at least one connecting housing unit which at least partially receives the sanding device. An internal wall of the connecting housing unit that delimits a fan receptacle region is configured for guiding an air flow generated by the fan. The internal wall is funnel-shaped about a rotation axis of a driveshaft of the drive device.
