1. Use a smaller-diameter carbide masonery bit to drill a pilot hole in

the
extractor.


Have you ever tried to drill hardened steel with a masonery bit?


Yep!

It worked well for what I needed it for.

Not exactly a "precision" bit, but CHEAP!


Have you ever tried to do this freehand on a char handle?


Dunno about "chars", but if the OP was able to drill the bolt freehand,
drilling the extractor won't be any more difficult.

Slower, perhaps, but no more difficult.



2. Use a sheetmetal screw to unscrew the extractor.


If you have deilled a hole in a piece of hardened steel were you ever
sucessfull in using a sheet metal screw to grab in a hole drilled into a
chunk of hardened steel?


All that is needed is for the taper of the sheetmetal screw to enable it to
jam against the side wall of the drilled hole.

The purpose of the sheetmetal screw is to be an extractor extractor. G


3. Use a new extractor to remove the bolt.


How may extractors are you going to sacrifice before you go to plan "B"?


2: The broken [perhaps defective] one and, if too much force is applied, a
replacement.

they come up with this striped stuff.
