Broken Screw Extractor

So you twisted the head off a brass wood screw — bummer. If you try to back out the remaining screw with a reverse-thread screw extractor, you may just deform the soft brass rather than remove it.  And if you grab the broken screw with pliers, you could end up doing more damage. It might be time to try these broken screw extractors from WoodCraft.

Chuck the screw extractors into your drill to bore a clean hole around the screw threads, and pull out the remaining plug, broken screw and all. You can easily patch the remaining hole with a bung, leaving little evidence of your error.

The 2″ long hollow extractors have saw toothed edges on both ends for twice the life. With the 3/8″ extractor you can remove up to #12 screws, while the 5/16″ and the 1/4″ extractors leave smaller holes when removing smaller screws.  They run about $10 to $12.

    Maybe not quite as good – but a cheaper alternative is to use a roll-pin of the appropriate size. A few swipes of a file on the roll pin’s leading edge and a single angled cut (keep in mind the direction that the pin will rotate – such tahat the angle cut acts like a tooth) at the edge of the pin’s vertical gap makes the pin a fairly effective single-flute hole saw.

    Great find Ben!

    This would a great tool for taking pallets apart. Those spiral shank nails are a nightmare to pry out, but this would let you just drill them out. There might be an issue with durability though. Anybody else got any ideas taking pallets apart?

    Ever tried to use a hole saw without a mandrel? Seems to me these screw extractors would be very difficult to use without securely clamping the piece down on a drill press. Certainly the aggressive teeth and the lack of shredded wood in the example seem to indicate it was done very carefully, and not with a mere drill.

  4. Brau, you’re right. Can’t slip anything by you guys.

    If you go to the product page on Woodcraft’s site, the first line in the description: “Using a drill press or a power drill with a pre-bored guide block…”

    Like you said, you probably want to clamp it down securely too. Sorry, I neglected to relay that important piece of information.
