Application: Screw removal kits are ideal for use with tools that require screws to be removed, including wall, wood, and metal plate bolts. The screw remover is compatible with most drilling and screwdriver handle tools. Suitable for bolts, machine screws, back cover bolts, wood screws, hex bolts, plate metal screws, and other types of screws. Material: The screw extractor is made of high-quality alloy steel material. This damaged screw extractor set is hard, reusable, efficient, durable, and resistant to high temperatures. The ultra-flexible drill extension is made of plastic and can be bent, twisted, and rotated at various angles. Easy to operate: Use this set to remove damaged screws and bolts in two simple steps. First, use a drill to make a hole in the fastener head, then insert the extractor to remove the fastener. Remove stripped screws in seconds. Be sure to run the drill in reverse direction during this process. Compatibility: Suitable for general sizes and various broken drill bits. Works with most electric hand drills. How to use the screw extractor: For sizes 6–10, install the extractor into the socket adapter first, then connect to the extension clip. (Other sizes can be directly connected to the extension bracket.) Set the drill to reverse mode and always use slow speed. Use a drill bit to drill a hole in the damaged screw. Place the extractor tip into the drilled hole. Slowly rotate the extractor counterclockwise while applying downward pressure until the extractor threads engage with the screw head. Turn slowly to loosen the screw from the material, then use pliers to remove it completely.
