Key Features

• Comprehensive 10-Piece System: This set includes five common left-hand screw machine (stubby) length drill bits (1/8", 3/16", 1/4", 5/16", and 3/8") and five corresponding square-style extractors, offering a complete solution for various fastener removal tasks.
• Professional-Grade USA Manufacturing: Engineered and produced in the USA, this kit meets professional standards for quality, robust durability, and consistent performance in challenging automotive and industrial applications.
• Efficient Left-Hand Drill Bits: Each left-hand drill bit features a 135° split point for fast, accurate starts without walking, along with three flats on the shanks to ensure a secure grip within drill chucks.
• Integrated Fastener Removal: The left-hand rotation of the drill bits is designed to back out broken bolts or studs during the drilling process, potentially reducing the need for a separate extractor in certain situations.
• Non-Marring Square Extractors: The unique square-style design of the extractors firmly engages the drilled fastener without expanding or damaging the surrounding material, facilitating clean and precise removal.

Applications

This R W THOMPSON INC set is an invaluable tool for professional mechanics, automotive technicians, and industrial maintenance personnel. It is suitable for the precise extraction of broken fasteners in critical assemblies, including engine compartments, transmissions, exhaust manifolds, and various machinery. Its compact design is particularly beneficial for working in tight spaces where standard extraction methods may be impractical. For optimal results, use the left-hand drill bits with the drill motor set in reverse mode, ensuring a minimum drilling depth of 1/2" into the fastener before applying an extractor.
