Forney Welding 20497 Stubby Left Hand Drill Bit 5/16 Inch HSS

The Forney 20497 is a high-speed steel (HSS) left-hand twist drill bit designed specifically for extracting broken studs, bolts, and screws. This stubby screw machine length drill bit features a 118-degree split point for precise starting and reduced walking, along with a surface-treated finish for enhanced durability.

Key Features:

• 5/16 inch diameter left-hand twist design
• High-speed steel construction for strength and wear resistance
• 118-degree split point for accurate drilling
• Stubby screw machine length for access in tight spaces
• Surface treated for extended tool life
• Requires reversing drill operation

Application: When used with a drill in reverse, the counterclockwise rotation often loosens and removes the broken fastener without requiring a separate screw extractor. This makes it an efficient first-step solution for extracting damaged hardware in automotive, machinery, and general repair applications.
