Impact wrench

Common card · No. 383760

An impact wrench is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing angular momentum in a rotating mass, then delivering it suddenly to the output shaft. In operation, a rotating mass is accelerated by the motor, storing angular momentum, then suddenly connected to the output shaft (the anvil), creating a high-torque impact. Compressed air is the most common power source, although electric or hydraulic power is also used, with cordless electric devices becoming increasingly popular since the mid-2000s. Impact wrenches are widely used in many industries, such as automotive repair, heavy equipment maintenance, product assembly, major construction projects, and any other instance where a high torque output is needed. For product assembly, a pulse tool is commonly used, as it features a reactionless tightening while reducing the noise levels the regular impacts suffer from. Pulse tools use oil as a medium to transfer the angular...
