Screw Extractor Kit | 22-Piece 1/4 Damaged Bolt Removal Set | High-Grade Drill Bits

This 22-piece 6.35mm (1/4-inch) damaged screw extractor set is engineered to remove stripped, broken, and seized fasteners with precision. The hardened steel extractor bits feature a reverse-fluted left-hand design that bites deeper under torque, providing maximum grip to back out stubborn screws and bolts without damaging the surrounding material. Features and Benefits - 22-Piece Comprehensive Set - Includes 11 extractor bits and 11 matching high-speed steel drill bits for every stage, from pilot hole to extraction, ensuring you have the right tool for the job. - 6.35mm (1/4-inch) Hex Shank - Provides a secure, non-slip fit in all standard hand drills, impact drivers, and drill chucks for reliable power transmission. - Heat-Treated Chrome Vanadium Steel - Offers superior hardness and wear resistance for extended tool life and consistent performance on hardened fasteners. - Reverse Spiral Flute Design - The left-hand threads engage the damaged screw head when turned counterclockwise, applying increasing removal force to extract the fastener cleanly. - Clearly Marked Sizes - Each extractor and drill bit is stamped with its size for quick, easy identification, saving time and reducing errors during critical repair work. Applications - Automotive Repair - Remove broken exhaust manifold studs, seized caliper bolts, or stripped oil pan screws without damaging engine blocks or components. - Furniture and Appliance Restoration - Safely extract stripped screws from antique wood furniture or modern appliances where surface integrity is paramount. - Machinery and Equipment Maintenance - Tackle rounded-off Allen bolts on bicycles, motorcycles, power tools, and outdoor equipment efficiently. - DIY Home Projects - The essential solution for common workshop frustrations like broken screws in decking, drywall anchors, or metal fixtures. Note For best results, always use a center punch to create a starter indent, select the correct size drill bit to create a pilot hole, and apply steady, firm pressure at low to medium speed during extraction.
