Pneumatic tools are powered by compressed air. Common types of these air-powered hand tools that are used in industry include buffers, nailing and stapling guns, grinders, drills, jack hammers, chipping hammers, riveting guns, sanders and wrenches.
A pneumatic tool is one that's driven with the assistance of compressed air rather than electricity. Generally speaking, all pneumatic tools require an air compressor to provide a pressurized burst of air to perform their operation.
Air ratchets, mechanical devices for controlling rotational motion, also come in standard sizes. Airbrushes are trigger-activated pneumatic tools that use nebulization to spray paint, ink, or dye. Pneumatic tools include grinders, sanders, drills, screwdrivers, hammers, and hack saws.
