Broken Tap Solution A while back some member asked about solving a problem about getting a broken tap out. One solution involved some kind of liquid that dissolved the tap in the hole w/o destroying the surrounding metal. I had saved this info but cannot find it. A search didn't help. Any one direct me to the original posting or the name of the product.Many thanks

Re: Broken Tap Solution I am extremely curious what would dissolve HSS but not iron. From what I know about metal... there isn't a chemical that would allow this type of reaction.

Re: Broken Tap Solution There are special broken tap extractors made for this. They work unless the broken tap is really jammed in. Try blowing out any chips with air, then use a flat punch to hit the end of the tap to hopefully loosen it a little, then use the extractor.

Re: Broken Tap Solution These is a machinist process called an Ellox machine which will shatter it to pieces and not touch the surrounding metal. But it is a specialized process and can be expensive.

Re: Broken Tap Solution Like Phillip suggested, EDM (Electric Discharge Machining) works very well. About 15 years ago I paid $25 to have a broken tap removed from an irreplaceable die cast zinc convertible top casting. Well worth the money. Also, your local vocational trade school may have this ability or know a shop that does it.

Re: Broken Tap Solution There are a lot of shops in the Los Angeles area that specialize in removing broken taps and bolts, probably due to the aerospace industry. You might ask around to see if there is anything in your area.

Re: Broken Tap Solution I would try to use needle nose pliers. Insert the ends into the flutes of the tap and turn in both directions to loosen stuck tap and unscrew. Tap has to be sufficient size for pliers to fit.

Re: Broken Tap Solution When I retired from Navy Civil Service, there was a machinist retiring also that set up a portable Ellox machine in a van and drove around fixing broken bolts, drills, taps, etc. Made very good money.
