Stupid question, but I'm assuming you can't get a pair of vice grips on the remaining tap to back it out?<div><br></div><div>Zach<br><br><div class="gmail_quote">On Tue, Jul 10, 2012 at 2:59 PM, Jake <span dir="ltr"><<a href="mailto:jake@spaz.org" target="_blank">jake@spaz.org</a>></span> wrote:<br>

<br>
If the tap broke off because you knocked the work off the table when you<br>
went to answer the phone that's one thing, but if the tap is broken<br>
because you were turning it, and it got stuck, it's stuck! And the tap is<br>
of course made of some pretty tough material.<br>
<br>
I saw the tap extractor you linked on amazon, it's made for 1/4" taps<br>
which are much larger. Do they make such things for such a small tap as<br>
6-32? i would be surprised.<br>
<br>
My guess is that you have three options:<br>
1. Move everything to the side 1/4", leaving behind the tap and the three<br>
other holes.<br>
<br>
2. Use a hardened punch to force the tap through the work, if you can get<br>
to the other side of the hole<br>
<br>
3. Pay a machine shop with EDI or EDM or whatever they call it, when they<br>
electrically destroy the piece of metal somehow. I think it's expensive.<br>

Does anyone know if we have a tap extractor for a 6/32 NC tap kicking<br>
around in the machine shop? On hole 3 of 4 I snapped my tap in a piece of<br>
aluminum and am trying to figure out how best to get it out.<br>
