The Spiral Extractor and Drill Bit 537 Series Combo Packs are designed to remove broken studs, bolts, socket screws and fittings. Its aggressive left hand spiral design is used for extra gripping power. The spiral flutes are designed to embed themselves deeper into the metal as you turn the tool, so as the fastener resistance increases, the extractor-Feet's grip increases.
