A pneumatic impact wrench is a powerful tool commonly used in automotive and construction industries. It uses compressed air to deliver high torque output, making it ideal for loosening or tightening bolts and nuts quickly. This tool is especially useful for tasks that require a lot of force, such as changing tires or assembling heavy machinery. The design of a pneumatic impact wrench allows it to work efficiently without overheating, as the air supply cools the tool during operation. Many professionals prefer it over electric wrenches because of its lightweight nature and ability to provide consistent power, making jobs easier and faster.
