Extracting a broken Extractor

(1/2) > >>

queen of spodes:
Have two broken 6mm bolts in the top and bottom triple clamp.   Tried soaking with kroil but couldn't get a hold on the exposed bolt.   I have a drill press that can drill a straight hole, so I carefully drilled out the center of both broken bolts without touching the threads.   Grabbed an extractor and started to twist one of the bolts out.   It cracked before I knew what happened.  This is what I get for using cheap Harbor Freight tools.

I left the second broken bolt alone, so it is still hollowed out.  

Now I have this, with a broken extractor inside the hole I drilled in the 6mm bold.



Tips for getting the bolt/extractor out?

my first atempt would be to weld a nut on it.

on 6mm size bolt (tiny)?  no welder so that's not even an option right now. 

kxpegger:
Because of the hardness removing broken taps, drill bits and extractors often requires a machinest that has an EDM (Electro Discharge Machine).

That EDM sounds expensive.   :evil:

I think I will grab a hacksaw and cut that stalk down about 5mm to see if I can grab onto the broken bolt with some pliers.  Then I can space out the numberplate with a spacer or washers for that matter.
