A pneumatic hand grinding tool has a supporting plate and a compressed-air pipe to be connected to a source of compressed air for driving the supporting plate. The supporting plate has a flat surface to which an abrasive sheet is to be attached by suction. For this purpose the supporting plate has ducts leading into the flat surface, which are connected to an ejector unit that forms a source of suction. The ejector unit is arranged on the tool and has members which connect the ejector unit to the compressed-air pipe. |
