Speed blabbered, again:

Once youve drilled a sufficiently large hole in the head it will separate
from the shank

Not with the smallest screw extractor and that's
just the one hole. If you drill a big enough hole
to see the head come off, you'd need to drill
a number of increasing sized holes.

Senile Ozzietard knows it all better, again and again and again... LMAO
