Abstract
A pneumatic rotation grinder comprises a housing (10) with a throttle valve controlled air inlet passage, a rotation motor drivingly connected to an output shaft (12) intended to carry a grinding tool, a safety guard (17) adjustably supported on the housing (10) in a coaxial disposition relative to the output shaft (12), and a lock device (26-28, 33-38) for arresting the safety guard (17) in desired angular positions relative to the housing (10). The lock device (26-28, 33-38) comprises both a latch (26-28) for positive coupling by engagement of teeth (26, 28) of the safety guard (17) relative to the housing (10), and a pressure air activated clamping device (33-38) for frictional arresting of the safety guard (17) relative to the housing (10).
