A pneumatic tool includes a housing defining an air inlet and first and second exhaust passages and an air motor fluidly coupled to the air inlet and disposed in the housing. The motor produces exhaust air in operation and is fluidly coupled to the first and second exhaust passages. The tool also includes an exhaust valve carried by housing for selectively opening and closing only the second exhaust passage.

[ What is claimed is:] [1.] A pneumatic tool comprising:a housing defining an air inlet, a first exhaust passage, and a second elongated exhaust passage having a first axis and fluidly coupled to the first passage;an air motor disposed in the housing and fluidly coupled to the air inlet and the first and second exhaust passages, the motor producing exhaust air in operation; andan exhaust valve spaced from the first exhaust passage and carried by the housing for selectively closing and opening only the second exhaust passage, the exhaust valve including a valve seat and a valve member rotatable about a second axis fixed with respect to the second exhaust passage and transverse to the first axis, the valve member being moveable between a closed position, wherein the valve seat and valve member form a seal preventing the exhaust air produced by the motor from flowing through the second exhaust passage, and a fully open position, allowing maximum flow of exhaust air out of the second exhaust passage.
