The dust collector includes a container connected to a flange (1) fitted on the drill housing and with ring seal (3) mounted rotatable in a circumferential indentation (26) of the flange part (1) opening towards the centre. The seal can be supported on the side walls of the indentation by felt rings (13,14). A pressure disc (19) and corrugated disc (20) can be arranged between a second side wall of the indentation and a second felt ring. The side of the pressure disc facing the second felt ring has projections (16).
