An endless abrasive article comprising a substantially constant width, a flexible backing, and an abrasive layer comprising a layer of abrasive grains fixed onto the backing by an adhesive make coat, wherein the abrasive layer comprises a plurality of cavities arranged in a series of parallel rows, the cavities being substantially free of the adhesive make coat and substantially free of abrasive grains fixed onto the backing, individual cavities in a row are separated from each other by a first distance, adjacent parallel rows are separated from each other by a second distance in a direction parallel with the width, and wherein the parallel rows defining an inclined direction wherein an angle between the inclined direction and the edges of the abrasive article is substantially 8, preferably in a range of 7.8 to 8.2, which provides inclined segments of abrasive layer uninterrupted by any cavity between adjacent parallel rows.
