Abstract: A sanding plate for a hand-guided electric power tool includes a receiving element and a carrier element. The receiving element is configured to fasten the sanding plate to a drive shaft of the electric power tool. In particular, the receiving element is configured to connect the sanding plate to the drive shaft in a rotationally fixed manner. The carrier element is formed of at least one yielding material. The carrier element is at least partially supported by a support element that is connected to the receiving element. The ratio of the radii of a circumcircle to circumscribe the carrier element to at least one circumcircle to circumscribe the support element is in the range of from 1.3 to 2. An electric power tool system includes a sander that has an oscillating drive shaft and the sanding plate.
