The handle on these assorted ESD-safe screwdrivers drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. They meet IEC 61340-5-1 requirements for protecting electronic devices from electrostatic discharge. Press the rotating end cap on the handle to apply constant pressure with your palm while turning the body of the screwdriver with your fingertips.
