【Product Features】

• Premium Material: Made from high-strength chromium vanadium steel (or nitrided/Ti-coated alloy steel), heat-treated for superior hardness and toughness, ensuring long-lasting performance.

• Efficient Design:

  • Left-Handed Spiral Flutes: Specialized fine-tooth threads bite firmly into broken screws when turned counterclockwise, generating powerful reverse force for smooth extraction.

【Applications】

Suitable for removing broken screws, bolts, taps, and studs from machinery, automotive/motorcycle engines, home appliances, plumbing valves, and more.

【Step-by-Step Usage】

1. Clean & Drill: Clear the broken screw surface. Use a center punch to mark the spot if needed.

2. Select Drill Bit: Choose a drill bit slightly smaller than the broken screw diameter (refer to the size chart).

3. Drill Guide Hole: Secure the drill bit in an electric drill and drill vertically into the center of the broken screw.

4. Choose Extractor: Select the appropriate extractor size based on the drilled hole depth and diameter.

5. Insert & Rotate: Insert the extractor into the hole. Use a compatible wrench to apply steady counterclockwise pressure until the broken screw is removed.

【Tips】

• Ensure the power is off and the work area is safe before operation.

• Beginners are advised to practice on scrap materials to familiarize themselves with the tool’s handling.

• For heavily rusted screws, apply penetrating oil beforehand to ease removal.
