Stripped, broken, or stuck screws driving you crazy? This Raynesys extractor kit is your rescue tool. It includes 10 drill bits and 10 matching extractors in sizes from #6 to #10, covering screws and bolts from 2mm to 12mm. Also comes with a magnetic socket adapter and a quick-change bit holder for use with your standard electric drill (not a hammer drill). Here's how it works: First, select a drill bit slightly smaller than the damaged screw and drill straight down into it (using reverse rotation on your drill—these are left-handed bits). Then, switch to the matching extractor bit, insert it into the hole, and slowly turn counterclockwise; the fluted design bites into the metal and pulls the screw out. Important tips: Use low speed (under 200 RPM), don't force it, and avoid using on extremely hard, heat-treated screws. The bits are made from hardened steel for durability. Everything stores neatly in a compact case. A lifesaver for DIY projects, automotive work, furniture repair, or fixing appliances. Get that stubborn screw out and save the day.
