Purpose and key benefit Lefthanded drill bit set designed to remove damaged, seized, or broken fasteners when used with screw extractors or a reversible drill. Reduces time and effort required to back out stripped screws, broken bolts, studs, and other stuck fasteners. Material and durability Manufactured from M2 steel for strength and wear resistance. Nitridecoated finish improves surface hardness and corrosion resistance for longer life. Function and compatibility Lefthanded rotation allows the bit to engage fasteners while the drill is set to reverse; works with screw extractors to remove broken fastener remnants. Attachable to standard reversible drills—suitable for use on screws, bolts, and studs. Designed for generalpurpose use around the house, in the garage, or on job sites. Performance and what it solves Helps extract broken or stuck fasteners without needing to remove surrounding components in many cases. Durable construction withstands the torque and friction of extraction tasks. Sizes included 1/4', 15/64', 7/32', 13/64', 3/16', 11/64', 5/32', 9/64', 1/8', 7/64', 3/32', 5/64', 1/16' Typical applications (use scenarios) Home : Remove a stripped wood screw or a rusted drywall screw during renovation without damaging adjacent materials. Automotive/garage: Extract a broken bolt or stud from an engine bracket or exhaust component using a reversible drill and screw extractor. Job site/maintenance: Clear stuck fasteners from metal framing or machinery during routine maintenance or teardown. Practical notes Use with an appropriate screw extractor or pilot drilling technique as required by the fastener condition. Operate reversible drill at controlled speed and torque to avoid damaging the extractor, bit, or workpiece.
