Pneumatic impact wrench, also known as ratchet wrench and power tool combination, is mainly a tool that provides high torque with minimum consumption. It uses a continuous power source to accelerate and rotate an object with a certain mass, and then instantly hits the output shaft, so that a relatively large output torque can be obtained.
Compressed air is the most common power source, but there are also electric or hydraulic sources, and battery-powered torque wrenches are also popular.
Pneumatic wrenches are widely used in many industries such as automotive repair, heavy equipment repair, product assembly (often called "impulse tools" and designed for torque output precise), major const projectsruction and installation of threaded screws. sets, and anywhere else where high torque output is required.
Pneumatic wrenches are available in all standard ratchet socket drive sizes, from small 1/4" drives for small tool assembly and disassembly, up to 3-inch drives, 5".
Pneumatic wrenches are generally not suitable for fixing installation parts whose fixing bodies are made of ceramic or plastic.
