AGT Professional Screw extractor set

You probably know this situation: When working with a cordless screwdriver, it's easy to damage a screw head, making it impossible to remove. Thanks to the extractor set made of hard HSS steel, this problem is now solved. Drill a hole into the damaged screw: Simply use the side with the drill bit and mill into the screw head until a sufficiently large recess is created. Then switch to the bit: Insert the extractor head into the previously milled hole of the screw head and turn slowly counterclockwise. This allows you to remove defective or damaged screws without damaging the threads. Designed for extracting defective and worn screws. Suitable for all common drills with a chuck. Extra-hard HSS steel for high wear resistance. Hardness grade according to Rockwell: 63 - 64 HRC. 4 sizes for different screw diameters: 3 - 5 / 4 - 8 / 5 - 10 / 6 - 12 mm. 4 screw extractors in a practical plastic box.
