49-Piece Bolt and Screw Extractor Set with Drill Bits for Professional Auto Repair

The extractors use a reverse left-hand spiral thread. When turned counter-clockwise onto a damaged fastener, the teeth bite in and grip harder the more torque you apply — spinning the bolt or screw free without needing to drill it out in most cases.

Yes. The socket end is standard 3/8" drive, making it compatible with electric impact drivers, air ratchets, and cordless drills using a socket adapter. Power tools are especially effective on heavily rusted or frozen fasteners.

This kit handles stripped hex and Phillips screws, rounded-off bolt heads, rusted nuts, frozen suspension bolts, and broken studs commonly found in automotive, machinery, and heavy equipment repair.

The bolt and screw removers are forged from Chromium-Molybdenum (Cr-Mo) steel and heat-treated for maximum strength and impact resistance. The drill bits are High-Speed Steel (HSS) with a titanium nitride coating for extended durability.

The HSS drill bit set includes 16 precision sizes ranging from 5/64" up to 1/2", covering the most common pilot hole requirements for extraction work on steel, cast iron, and aluminum.

This is a professional-grade tool set designed for users with prior mechanical experience. Proper technique — including correct drill speed and counter-clockwise torque application — is important to avoid injury or further damage to the workpiece.

Generally, select the extractor that fits snugly over the damaged bolt head. For the screw extractors, drill a pilot hole first using the matching HSS bit, then insert the extractor and turn counter-clockwise. The kit's size range typically covers 1/4" through 3/4" bolt heads and 1/8" through 1/2" screw diameters.
