    Abstract: The invention relates to a nailcare device, comprising a housing (1) and a discoid grinding body (4), driven by an electric motor, sitting on a driveshaft (10), connected to an electric motor (6). The essentially discoid grinding body (4) is arranged in the upper part of the device housing (1), beneath a cover or plate (3), parallel to the upper side (4a) of the grinding body (4), fixed to the housing (1) of the device in an easily detachable manner and with at least two slots (3a) for the fingernail of the user as close as possible to the grinding body (4) at differing radial separations from the driveshaft (10). The cover or plate (3) can be funnel- or cone-shaped with relation to the grinding body (4), such that the axial separation between the upper side (4a) of the discoid grinding body (4) and the slots (3a), arranged at various radial separations from the driveshaft (10), increases or decreases with increasing separation from the driveshaft (10).
