Irwin 5 Piece Spiral Flute Screw Extractor Set

Features:

• 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
• The extractor size and recommended drill bit size are etched on each tool.
