A pneumatic power tool comprises a housing ( 10 ), a motor, a pressure air inlet passage ( 11,15 ), an exhaust air outlet passage ( 12,17 ), and an exhaust air outlet flow deflector ( 14 ) including an outlet piece ( 20 ) with radial as well as axial outlet openings ( 25, 26 ) and a valve element ( 21 ) with radial as well as axial apertures ( 30, 28 ), wherein the outlet piece ( 20 ) and the valve element ( 21 ) are rotatable relative to the housing ( 10 ) as well as to each other to bring alternatively a radial opening ( 25 ) of the outlet piece ( 20 ) into or out of alignment with a radial aperture ( 30 ) of the valve element ( 21 ), and at the same time bring the axial apertures ( 28 ) of the valve element ( 21 ) out of or into alignment with the openings ( 26 ) of the outlet piece ( 20 ), thereby shifting the exhaust outlet flow direction as desired between a radial direction and an axial direction.
