The mounted flap wheels FAPI-FLEECE consist of individual non-woven lamellae. The lamellae are fastened fan like around the tool’s axis. During operation, the mounted flap wheel works elastically – because of its non-woven web surface – and adapts easily to the shape or contour of the respective workpiece. The mounted flap wheel has a shaft diameter of 6 mm and can be used easily on hand grinders and satin finishers.
