摘要: A pad is disclosed comprising a monobloc body (10, 11), traversed by a plurality of peripheral through holes (3) for aspirating dust, wherein channels (4) are formed that extend parallel to the lower surface of the pad connecting a lower central aspiration hole (33) of the pad with peripheral holes (3C). The channels (4) intercept lower internal holes (101) of the pad that do not pass through the monobloc (10, 11) that are suitable for conveying the abraded dust from the central part of the pad to the peripheral holes (3C) through the channels (4).
