This DeWalt ClicFix Bit Holder is a magnetic quick change bit holder ideal for accessing tight spaces and awkward screws. Its solid construction withstands abuse in impact applications, and it features a strong quick-release tip for a secure grip. The bit holder acts as an interface between the chuck and the screwdriver on your drill or impact wrench. The hexagonal steel bar end grips onto the chuck, while the chrome steel cylinder end connects to the screwdriver. A magnet in the bit holds the screw steady, and the tip locks into place to prevent the bit from coming off with the screw, with a quick-release mechanism for fast bit changes. The steel frame is robust, preventing damage and denting, and its chrome finish resists corrosion. With a compact frame, it's easy to store and compatible with most brands of corded or cordless drills. It has a quarter-inch hex bit holder size and is 60 mm in length.
