FIELD: various technological processes; construction.
SUBSTANCE: invention relates to tools used in finishing works, in particular to tools for finishing plastered surfaces, in particular to a grinding device. Grinding device comprises a rigid abrasive plate in the form of a rectangular parallelepiped, to the first plane of which an abrasive material is attached, and to another plane, opposite to the first one, a rigid base is detachably connected, besides, ends of the abrasive plate are coated with a smooth polymer layer.
EFFECT: reduced sliding friction of abrasive tool end face and reduced damages caused by abrasive tool end face during grinding in corners and/or slopes of window or door openings caused by friction of abrasive tool end face.
