ABSTRACT:
A pneumatic grinding machine provided with a dust collector which partly surrounds the grinding tool and which is connected to a suction source through a dust conveying conduit. The maneuverability of the machine is improved by utilizing rotatable connections for the dust conveying conduit as well as for the pressure air supply conduit and by arranging said connections rotatable relative to the machine for rotation about a common axis. The rotatability of these conduits is accomplished by swivel means disposed as the outer end of a machine handle. Alternatively, the connections are associated with the dust collector.
