What is an example of an air-powered tool?

A pneumatic-impact wrench is considered an air-powered tool because it operates using compressed air to generate rotational power. This tool is commonly used in various industrial and automotive applications, particularly for tasks that require high torque, such as fastening and loosening bolts and nuts. The use of compressed air allows for efficient power delivery and quicker operation compared to manual tools.

In contrast, the other options listed operate on different principles. Electric drills are powered by electricity rather than air, chain saws typically use gasoline engines or electric motors for power, and hydraulic power saws rely on hydraulic fluid to operate. Each of these tools functions effectively within its own context but does not fall under the category of air-powered tools like the pneumatic-impact wrench does.
