A surface treatment tool comprising an annular carrier substrate and a plurality of abrasive lamellae connected to the carrier substrate by their narrow sides in a contacting side-by-side arrangement or juxtaposition of their flat sides, at least some of which are fiber fleece lamellae. The carrier substrate is a flexible belt, the ends of which pointing in the longitudinal extension of the belt are connected to one another to form an annular shape. The fiber fleece lamellae are connected to the outward-facing surface of the flexible belt by means of an adhesive connection with flexible material properties in a state in which the lamellae are elastically compressed with respect to their thickness.
