Forney Welding 20493 Stubby Left Hand Drill Bit 1/4 in HSS

The Forney 20493 is a 1/4-inch stubby left-hand drill bit designed specifically for drilling out and removing broken studs, bolts, and screws. Constructed from high-speed steel (HSS) with a surface treatment for enhanced durability, this specialized bit features a 118-degree split point for accurate starting and reduced walking.

Key Features:

• Left-hand twist design rotates counterclockwise to help back out broken fasteners
• Stubby screw machine length for access in tight spaces
• High-speed steel construction for strength and wear resistance
• 118-degree split point for self-centering and faster penetration
• Surface treated for extended tool life
• 1/4-inch diameter

How It Works: This bit requires a reversing drill set to counterclockwise rotation. In many cases, the left-hand rotation creates enough grip on the broken fastener to spin it out during drilling, eliminating the need for a separate screw extractor. If the fastener doesn't back out on its own, the drilled hole provides a pilot for extractor use.

Ideal for automotive repair, machinery maintenance, and any application where broken fasteners need removal without damaging surrounding threads.
