Pneumatic power tools, also known as air-powered tools, are devices that are powered by compressed air. These tools use the force of compressed air to perform a wide range of functions, from drilling and cutting to sanding and grinding.

Pneumatic power tools are commonly used in many industries, including construction, automotive, woodworking, and metalworking. They are popular because they are lightweight, durable, and require minimal maintenance compared to electric power tools.

Some common examples of pneumatic power tools include pneumatic drills, air hammers, impact wrenches, sanders, grinders, and spray guns. These tools typically have a trigger mechanism that activates a valve to release compressed air from an air compressor, which then powers the tool's motor.

One advantage of using pneumatic power tools is that they can be more powerful than their electric counterparts of the same size. This is because compressed air can be stored at a very high pressure, which allows the tools to produce more torque or force than an electric motor of the same size.

However, one potential drawback of using pneumatic power tools is that they require a source of compressed air, which means that an air compressor is needed. This can add to the cost and complexity of using these tools, especially if a large and powerful air compressor is required.
