The Chicago Pneumatic, RediPower, Desoutter, and Ingersoll Rand impact wrenches we carry are of the highest quality available. These companies have many years experience in manufacturing and repairing these tools, and with proper maintenance these impacts can handle heavy extended usage. Impact wrenches differ basically from screwdrivers and nutrnunners in the method by which torque is applied to the fastener. Screwdrivers and nutrunners have high torque motors which deliver torque directly to the fastener until air is shut off or a limiting clutch in the tool functions. The operator must resist the tendency of the tool to rotate in the opposite direction. An impact wrench has a relatively low torque motor which imparts rotary inertia to a special type of clutch. The clutch converts this inertia into a series of rotary blows which gradually build up torque in the fastener. The effect is similar to that obtained when a hand wrench is placed on a nut and the opposite end is struck with a hammer. Torque reaction is not transmitted back through the tool to the operator, therefore fasteners can be safely tightened to high torques with hand-held tools.
