The Vermont American 13470 Left Hand Drill Bit is a specialized tool engineered for professional technicians and mechanics. It is designed to efficiently address the challenging task of extracting broken, right-hand threaded fasteners, preventing further tightening during the drilling process. This precision-constructed 5/16-inch diameter drill bit delivers reliable performance for critical repair situations in demanding automotive and industrial environments.
Key Features
- Left-Hand Twist Design: Expertly engineered to facilitate the extraction of broken, right-hand threaded fasteners by preventing further tightening. This reverse cutting action can often back out the fastener as drilling progresses.
- Optimal 5/16 In. Diameter: A versatile size suitable for a wide array of common stud and bolt extraction tasks across various automotive and industrial applications.
- 118-Degree Point Angle: Provides a robust and versatile cutting edge, making it suitable for general-purpose drilling applications where a left-hand rotation is specifically required.
- Professional-Grade Construction: Built for exceptional durability and consistent performance in rigorous workshop and industrial settings, often crafted from high-speed steel (HSS) for superior resistance to high temperatures and wear.
- Versatile Tool Compatibility: Designed for efficient integration with reversible drills, lathes, and milling machines, accommodating a broad range of tool holding systems.
Applications
This specialized left-hand drill bit is primarily utilized for the critical task of extracting broken, right-hand threaded studs and bolts, a frequent challenge encountered in engine repair, chassis work, exhaust system maintenance, and general machinery upkeep. Its unique design actively helps prevent the broken fastener from seizing deeper into the material, significantly easing subsequent extraction efforts. It serves as an ideal companion for use with screw extractors, enhancing their effectiveness in removing compromised fasteners. Beyond extraction, its 118-degree point makes it suitable for general-purpose drilling in scenarios where a left-hand rotation is preferred or necessary for specific machining operations.
