ABSTRACT:
In order to improve a grinder comprising a grinding tool which is oscillatingly driven through a small pivot angle about a pivot axis fixed on the grinder and which has a grinding surface with at least one corner region, with at least one suction channel extending throughout the grinding tool from an aspirating port to an exhaust port located on a side facing away from the grinding surface, so as to obtain an effective, reliable and, in particular, subsequently attachable dust exhaust system which is designed as simply as possible and does not impair handling of the grinder, it is suggested that the exhaust port be arranged outside of the corner region and that an exhaust hood which can be immovably fixed on the grinder be provided so as to cover the exhaust port in all pivoted positions and allow the corner region of the grinding tool to protrude in an uncovered manner.
