An Air Angle Grinder is a pneumatically powered rotary grinding tool designed for cutting, grinding, deburring, surface preparation, and polishing of metal, stone, or composite materials. It is driven by compressed air, which spins an abrasive disc mounted at a right angle (90°) to the tool body — allowing high control, excellent visibility, and easy access to flat or cornered surfaces. Because it produces no electrical sparks and runs cool during long operation, it is ideal for industrial fabrication, shipbuilding, foundries, automotive repair, and maintenance in hazardous environments.
