A hand-held pneumatic grinding tool is provided with two angularly spaced handles (12, 13), one containing an air supply passage (16) and a throttle valve, the other an air exhaust passage (17) and a silencer (15). Both handles (12, 13) are adjustably mounted on the tool housing (10) by means of arc-shaped mountings. These comprise opposed arc-shaped V-grooves (22, 23 and 37, 38), resp. on the housing (10) and mating V-ridges (24, 25 and 35, 36), resp. on the handles (12, 13). Arc-shaped wedge elements (27, 43) are retained by clamping bolts (28, 44) to engage one of the V-ridges (24, 25 and 35, 36 resp.) on each handle and, thereby, locking the handles (12, 13) in desired positions relative to the housing (10). |
