Spiral Extractor and Cobalt Drill Bit Set

• Designed to remove broken studs, bolts, socket screws and fittings
• Aggressive left hand spiral design for extra gripping power
• Spiral flutes are designed to embed themselves deeper into the metal as you turn the tool, so as the fastener resistance increases, the extractor's grip increases
• Extractor size and recommended frill bit size are etched on each tool
• Set includes metal index case

Set includes spiral flute screw extractors in sizes: Ex-1, Ex-2, Ex-3, Ex-4, Ex-5, and drill bits in sizes: 5/64", 7/64", 5/32", 1/4" and 19/64".
