Abstract: An automatic shut-off of a vacuum line for a tool having a first hose portion and a second hose portion, the portions of hoses being in fluid communication with each other. A first member is disposed in the first hose portion and the first member is moveable between a first position and a second position. A valve is disposed in the second hose portion, wherein the valve is movable between an open position and a closed position. A second member operatively interconnects the first member and the valve. The first member operatively moves said second member to open and close the valve. When the tool is being operated the first member will move, thus opening the valve, to allow a vacuum through the tool. Also, the automatic shut-off significantly reduces noise produced by the tool during operation.
