Pneumatic Screw Driver is a handheld power tool that is powered by compressed air and used for driving screws into various materials. It features a motor that rotates a screwdriver bit, which is designed to fit different types of screw heads. The tool also typically includes an adjustable torque setting, which allows the user to adjust the amount of force applied to the screw, and a reversible mechanism for easy removal of screws. Pneumatic Screw Drivers are commonly used in industrial and manufacturing settings, as well as in automotive repair, where high volumes of screws need to be driven quickly and accurately. They are often preferred over electric screwdrivers for their reliability, durability, and ability to operate at high speeds without overheating.
