9-Piece Screw Extractor & Twist Drill Kit A professional-grade solution for removing stubborn fasteners, this kit combines durability, versatility, and efficiency—ideal for home repairs, DIY projects, and professional machinery maintenance. Product Parameters: 6-Piece Screw Extractor Set: Material: High-performance HSS 6542 (63-65HRC hardness) – far tougher than standard HSS 4341, with excellent wear resistance and anti-deformation properties, ensuring long-term use without breakage. Sizes: #0, #1, #2 , #3, #4 – covers everything from tiny electronic screws to large machinery bolts. 3-Piece Twist Drill Bit Kit: Material: Premium M35 carbide – designed for pre-drilling tough, hard-to-remove screws, with strong cutting power to destroy screw structures for easier extraction. Sizes: 2.0cm, 3.0cm, 3.5cm – perfectly matched to the extractors for seamless workflow. Instructions: Drill a Pilot Hole: Mount the M35 twist drill bit to your tool, rotate clockwise, and apply gentle pressure to drill vertically into the broken/stripped screw. Drill as deeply as possible—deeper holes enhance the extractor’s grip. Attach the Extractor: Swap the drill bit for the appropriate screw extractor. Extract the Screw: Rotate the extractor counterclockwise with steady pressure . If grip is insufficient, switch to a larger extractor size to ensure secure removal. Note: To prevent rust during storage, the extractors and drill bits are coated with rust-protection oil—you may notice slight stickiness upon unboxing; this is normal and does not affect performance.
