An Impact Screwdriver (sometimes called an Impact Driver) is a hand or power tool designed to drive or loosen screws, bolts, and fasteners that are difficult to move with a regular screwdriver. It delivers strong torsional impact force combined with a rotary motion, making it ideal for tough applications.
