PURPOSE: An air grinder is provided to improve the space utilization by collecting dust with the impeller of a grinding plate which is rotated by high pressure air without a separate power supply. CONSTITUTION: An air grinder comprises a dust collection unit(130). The dust collection unit collects dust of an internal space(10) and discharges the dust to outside with the torque of a grinding plate(111). A sealing member of the dust collection unit seals a work part to form the internal space. The sealing member of the dust collection unit is freely transformed corresponding to the shape of the work part.
