摘要： A cutting and dust or slurry collecting assembly that comprises: a) a circular saw blade (4) b) a blade guard (5) c) a cover device (6), and the cover device (6) has a front end (31), a rear end (32), a top surface (34), a bottom surface (36), elongated sidewalls (35), and a longitudinal passage (45, 46) for the saw blade, d) the blade guard (5) and the cover device (6) being pivotally connected or connectable to one another via a hinge (40) in or adjacent to a lower rear corner of the blade guard (5), such that the cover device and the blade guard can be turned in relation to each other, e) a discharge member (52) is provided at the rear of said hinge and has an outlet (58) which can be connected to a vacuum source, f) a connection member (12) connects the discharge member (52) with at least one of the longitudinal passage (45, 46) and the cut created rear of the longitudinal passage, g) that the direction of rotation of the saw blade (4) is such that a circumferential part of the blade whiRch has passed beyond the bottom surface of the cover device will move in a direction upwards-rearwards towards the bottom surface In particular a rear arm distance (Lr) between the hinge (40) and the rear end (32) is bigger than 0,2R and preferably bigger than 0,25R, thereby enabling a turning of the cover device (6) by pressing the rear end (32) towards the structure to be cut.
