Duke Tools 6 Piece Screw & Bolt Extractor Set
The Duke Tools Screw Extractor Set—double-ended design removes seized screws without surface damage
Product Description
The Duke Tools 6 Piece Screw & Bolt Extractor Set provides a robust solution for extracting damaged or seized fasteners, fabricated from HSS 4341 alloy steel—an economical high-speed variant with 0.95% carbon, 4.25% chromium, and 1.1% molybdenum for balanced red hardness (retaining HRC 62-64 at 550-600°C) and toughness—this set features double-ended bits with aggressive left-hand spiral flutes that grip and back out broken screws upon reverse rotation.
Each 51 mm bit integrates a pilot drill tip for initial hole preparation (Ø2-10 mm) without requiring separate tooling, compatible with 1/4″ hex chucks in variable-speed drill drivers (300-800 RPM forward for drilling, low-torque reverse <20 Nm for extraction) and impact drivers under controlled pulses to avoid bit fracture. Suited for soft-to-medium materials like mild steel (up to 250 HB), aluminium alloys, and hardwoods, the uncoated finish promotes heat dissipation during friction-heavy tasks.
Key Features & Benefits
- Double-Ended Spiral Design: Combines tapered drill point with left-hand extractor flutes for one-tool workflow, enabling self-tapping grip that extracts fasteners up to 1.5x diameter depth without cam-out, per ISO 8992 guidelines for thread removal.
- HSS 4341 Alloy Composition: Delivers superior wear resistance (abrasion index <0.3 mm³/Nm) and thermal stability, extending bit life to 200+ cycles in rusted ferrous applications versus standard carbon steels.
- Reverse-Mode Compatibility: Optimised for low-speed reverse in cordless drivers, with flute geometry that applies counter-torque up to 30 Nm, preventing further thread stripping in seized conditions.
- Universal Material Versatility: Handles extraction in metals (e.g., galvanised steel, timbers, and composites, with minimal workpiece distortion (<0.1 mm radial expansion).

FAQs & Technical Guide
Get expert advice, in-depth answers, and practical tips to make the most of your Duke Tools 6 Piece Screw & Bolt Extractor Set. This guide addresses common queries on usage, maintenance and safety.
How do I prepare a hole for extraction using these bits?
In forward mode at 400-600 RPM, use the drill end to create a pilot hole to 75% of fastener diameter (e.g., Ø4 mm for M5 bolt), applying light cutting oil for ferrous metals; retract every 5 mm to clear chips and preventing binding.
Can these extractors handle rusted stainless steel fasteners?
Suitable for 304/316 grades up to M8 with penetrating oil (e.g., CRC 5-56) applied 30 minutes prior; HSS 4341’s toughness resists galling, but for M10+, use heat (torch to 200°C) to break seizure without exceeding 600°C tool threshold.
What torque settings are safe for reverse extraction on an impact driver?
Set to low pulse (10-20 Nm) with clutch engaged; the left-hand flutes engage at 5-10 Nm, backing out the fastener—exceeding 30 Nm risks bit shear, so monitor for vibration.
Are these bits suitable for wood or plastic extractions, and what precautions?
Yes, for particleboard or PVC fixings, but reduce RPM to 200-300 and use without oil to avoid splintering; the spiral design minimises delamination (<0.5 mm tear-out), but test on scrap to confirm grip without over-torquing.
