Tools powered by compressed air, known as pneumatic tools or air tools, include a variety of power tools used in construction, automotive repair, woodworking, and industrial applications. Common types of pneumatic tools are drills, orbital sanders, socket wrenches, air hammers, brad nailers, grease guns, angle grinders, impact wrenches, air ratchets, air chisels, needle scalers, and nail guns. These tools operate by using compressed air from an air compressor to generate mechanical action for tasks such as drilling, sanding, tightening bolts, nailing, grinding, hammering, and spraying. Pneumatic tools are favored for their high power-to-weight ratio, durability, and ability to run continuously without overheating, making them efficient and precise for various professional and home improvement projects.
