Description
22-Piece Screw Extractor Set — HSS Damaged Bolt Remover Kit with DR Drill Bits & EX Extractors
A stripped screw head or broken bolt can bring any repair job to a complete stop — and the wrong extraction tool can make the situation worse. Whether you're pulling a rusted screw from a deck board, removing a broken bolt from an engine block, or salvaging a stripped fastener from a cabinet hinge, you need extractors that bite cleanly and back out reliably. This 22-piece screw extractor set is built for mechanics, woodworkers, and DIYers who need a complete, size-matched extraction system in one organized case.
The kit includes 10 EX screw extractors (sizes 1#–10#, covering 1.0mm to 12mm diameter), 10 matching DR left-hand drill bits (same size range), 1 extension bit holder, and 1 socket adapter — 22 pieces total, stored in a molded plastic organizer (13cm x 10cm x 3cm, approx. 200g). All pieces are machined from High-Speed Steel (HSS) for hardness and edge retention across repeated use.
Use this set for removing stripped Phillips and hex screws from wood furniture and decking, extracting broken bolts from automotive components, pulling seized fasteners from appliances and electronics, and general repair work wherever a damaged fastener is blocking progress. The included socket adapter makes the extractors compatible with standard ratchets and impact drivers.
Compatible with: Standard Corded & Cordless Drills · Ratchets (via socket adapter) · Impact Drivers · Extension Bit Holders
For best results, apply penetrating oil to seized fasteners before extraction. Not designed for hardened alloy steel fasteners above HSS hardness rating. Always wear eye protection during use.
✅ Key Features of This Damaged Screw Extractor Set
- 22-Piece DR + EX System: 10 left-hand DR drill bits create the pilot hole; 10 matching EX extractors grip and back out the fastener — size-matched pairs from 1.0mm to 12mm diameter for precise, controlled extraction.
- Reverse Left-Hand Extraction: Counter-clockwise turning action bites harder into the damaged fastener the more torque you apply — the same motion that removes the screw also tightens the extractor's grip.
- High-Speed Steel (HSS) Construction: All 20 drill bits and extractors are machined from HSS for the hardness needed to drill into and grip damaged, rusted, or stripped fasteners without deforming.
- Socket Adapter & Extension Holder Included: The socket adapter connects extractors to standard ratchets and impact drivers; the extension bit holder reaches fasteners in recessed or hard-to-access locations.
- Wide Size Range (1.0mm–12mm): Ten extractor sizes cover everything from small electronics screws to large structural bolts — one kit handles the full range of fastener sizes encountered in automotive, woodworking, and home repair.
- Molded Organizer Case: All 22 pieces snap into individual slots in a compact 13 x 10 x 3cm case — DR and EX pieces stay paired by size, ready to grab without sorting through loose hardware.

❓ Frequently Asked Questions
How does a screw extractor work?
The DR drill bits create a pilot hole in the damaged screw head. The matching EX extractor is then inserted into the pilot hole and turned counter-clockwise — the left-hand spiral threads bite into the screw and back it out as torque is applied. The more torque you apply, the tighter the extractor grips.
What is the difference between the DR and EX pieces in this kit?
DR pieces are left-hand drill bits used to create a pilot hole in the damaged fastener head. EX pieces are the actual extractors — they are inserted into the pilot hole and turned counter-clockwise to grip and remove the fastener. Each DR and EX pair is size-matched for the same fastener diameter range.
What screw diameters does this 22-piece set cover?
The set covers screw diameters from 1.0mm up to 12mm across 10 extractor sizes (EX 1#–10#) and 10 matching drill bit sizes (DR 1#–10#). This range covers small electronics screws through large structural bolts.
Can this set remove rusted or seized screws?
Yes. The HSS construction and reverse-thread extraction design are effective on rusted, seized, stripped, and broken screws. For heavily corroded fasteners, applying penetrating oil and allowing it to soak before extraction generally improves results significantly.
What tools do I need to use this extractor set?
The DR drill bits work with any standard corded or cordless drill. The EX extractors can be used with the included socket adapter and a ratchet or impact driver set to reverse, or with a drill set to reverse rotation. The extension bit holder is also included for recessed fasteners.
What materials can these extractors work on?
These screw extractors are suitable for removing damaged fasteners from wood, plastic, aluminum, and general mild steel. They are not designed for hardened alloy steel fasteners that exceed the HSS hardness rating of the extractors themselves.
How do I choose the right extractor size for my screw?
Match the extractor size to the diameter of the damaged screw. Each EX extractor lists its compatible diameter range (e.g., EX 3# covers 4.0–8.0mm). Select the DR drill bit of the same number to drill the pilot hole first, then use the matching EX extractor to remove the fastener.
