1. Prepare the Fastener: Ensure the broken or stripped fastener is accessible and clean. If the fastener is broken below the surface, a pilot hole must be drilled.
2. Drill a Pilot Hole (if necessary): Using a drill bit slightly smaller than the extractor, drill a straight hole into the center of the damaged fastener. The depth of the hole should be sufficient for the extractor to get a firm grip. For best results, use a drill guide to keep the hole centered and straight.
3. Select Extractor Size: Choose the extractor that fits snugly into the pilot hole. The extractor should be large enough to provide sufficient torque without breaking, but not so large that it cannot enter the hole.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ

1. Insert Extractor: Insert the selected spiral flute extractor into the pre-drilled pilot hole. Tap it gently with a hammer if needed to ensure it seats firmly.
2. Attach Turning Tool: Use an appropriate turning tool, such as a tap wrench or adjustable wrench, to grip the square end of the extractor.
3. Extract the Fastener: Slowly turn the extractor എതിർ ഘടികാരദിശയിൽ. As you turn, the left-hand spiral flutes will bite into the metal of the damaged fastener. Apply steady, even pressure while turning.
4. Continue Turning: Continue turning counter-clockwise until the damaged fastener loosens and can be removed. If resistance is high, apply penetrating oil and allow it to soak before attempting again.

• Extractor slips:
  • Ensure the pilot hole is drilled to the correct size and depth.
  • Verify the extractor is fully seated and gripping the fastener.
  • Try a slightly larger extractor if the hole allows, or re-drill the pilot hole if possible.
• Fastener does not turn:
  • Apply penetrating oil to the fastener and allow it to soak for several minutes.
  • Gently tap the extractor with a hammer to help break the bond of the fastener.
  • Ensure you are turning the extractor എതിർ ഘടികാരദിശയിൽ.
• Extractor breaks:
  • This usually indicates excessive force or an improperly sized pilot hole.
  • Removing a broken extractor from a fastener can be challenging and may require specialized tools or professional assistance.
