The Sealey 10 Piece Step Drill Screw and Bolt Extractor Set is a professional-grade tool kit designed for removing damaged, broken or seized fasteners. This comprehensive set combines heat-treated Chrome Molybdenum steel screw extractors with fully ground step drill bits to tackle stubborn removal jobs efficiently. The step drill bits create precisely tapered conical holes that work in conjunction with the corresponding extractors to provide superior grip on damaged fittings. This matched system is ideal for removing right-hand thread broken or seized screws and bolts across a wide range of sizes, from small 2.5mm fasteners up to larger 14mm bolts. The extractors feature a special design that cuts into the side of the drilled hole, allowing increased torque application when removing heavily seized fittings. This side-cutting action provides greater leverage and grip compared to standard extractors, making it easier to remove fasteners that would otherwise require drilling out completely. The set arrives in a protective storage case to keep the tools organised and ready for use on site.
