Pneumatic tools are powered by:

Pneumatic tools are specifically designed to operate using compressed air as their power source. The compressed air creates a pressing force that drives various mechanisms within the tool, allowing it to perform heavy-duty tasks efficiently. This method of power is particularly advantageous because it offers a high power-to-weight ratio, making pneumatic tools lighter and easier to handle compared to many electric or hydraulic tools.

Using compressed air allows for rapid operation and can be more durable in rugged environments since they have fewer moving parts that can wear out under heavy use. This is a key reason why many construction and rescue operations favor pneumatic tools for tasks such as drilling, cutting, and fastening.

Other power sources like electricity, hydraulic fluid, and battery power relate to different types of tools but do not fit the definition of pneumatic tools specifically, as they do not rely on compressed air for their operation. This distinction highlights the unique characteristics and advantages of pneumatic tools in various applications.
