2076344 9206821 PCTABS00011 The invention relates to a rotary tool consisting of a drive hub (N) and an interchangeable tool sleeve (H), whereby the tool sleeve (H) can be connected solidly in rotation with the drive hub (N) and has projecting engagement means on its outer circumferential surface for machining equipment. Here, the drive hub (N) consists of a drive flange (1) and a securing flange (2), whereby on the drive flange (1) axially on the outside is coaxially fitted a central motor connection (3) and at least one of the flanges (1, 2) has at least one axial projection (A) axially on the inside. For each axial projection (A) there is an axially opposite second axial projection (A) or recess or aperture on the other flange (1 or 2) suitably arranged and at least one axial projection (A) can be arranged radially eccentrically. Here, at least one axial projection (A) forms an axial conveyor arm (4, 5). At least one axial projection (A) engages between the two flanges (1, 2) in a part of the opposite flange (1, 2) in such a way that the flange (1, 2) cannot rotate in relation to their shaped spindle. Here it is an essential part of the invention that the securing flange (2) engages closely with the driving flange (1) via at least one snap connector (9, 10) and can be released by release means.
