[DML] Re: advice on stubborn bolt

["twinenginedmc12" <twinenginedmc12@xxxxxxxxxxxxxxxxx>]

Hello.

Yes, it will be difficult to remove the screw extractor.  When I once 
broke my screw extractor in the bolt I was trying to remove, I ended 
up buying a diamond tipped cutter for my Dremel tool, which I used to 
cut the material around the extractor away with.  Eventually, I had 
cut away enough material to grasp the extractor with needlenose 
pliers.  After that I drilled the broken bolt.

It worked, but it took a long time, left a nasty irregular hole, and 
required a thread insert.

Now I only use higher quality expensive name brand extractors.

Rick.
