A fluid metering device for a compressed fluid operated tool is incorporated in a compressed air operated, vibration dampened percussive tool which has a handle assembly (1) and a cover (4) surrounding a barrel (5) and piston assembly (12) which are caused to oscillate relatively to the handle assembly (1). The barrel assembly (5) receives a tool retainer (11). A trigger (2) controls primary air supply through a line (3). To reduce air consumption when the tool is not actually applied to a workpiece and thereby to reduce exposure of the operator's hand/arm to vibration, an air metering device is provided. The device includes a tube (16) slidably mounted in a bush (17) and having a bleed hole (21) in an end of the tube which enters the bush (17). In one position of the tube within the bush, a series of apertures (22) in the wall of the tube are sealed by the bush and in another position of the tube within the bush are exposed. The tube (16) connects the air line (3) with the piston assembly (12) and moves within the bush responsive to pressure applied by the actual tool on the workpiece.
