No - it's true -
they are very handy if you are trying to remove a bolt that is broken off
inside a block of metal.
When the drill catches it can even undo the bolt or screw.

A m>f tranny works at my local Bunnings and the other day I was buying a tube of silicone. At the counter I had to bite my lip to stop myself from laughing when I asked if s/he had a nozzle.

Absolutely true.
Although not very common.

Invaluable when removing bolts and screws because they don't twist the screws in deeper, or worse, into a component or assembly while attempting to remove it.

I must admit though.
As a tradesman of many years, I have never seen a full set presented like that.
Usually you buy them individually or in small sets.

And no, you don't need to use a left hand drill when drilling holes for left hand threads.

Yes - I've used them - they are excellent and should be the first choice
before trying an easy out - screw extractor.
Also - put Penetrene on the threads for one day first to try and loosen them.

Well I'm still happy with my left-handed Crescent Nail Remover, hammer and ear-muffs.

There are even left handed shifters.
True
I have seen one
The thread is the opposite of tge right hand one

I'm at a loss to see the usefulness of it though
It's like a bwyannnn
It's there but no one knows why or what it's for.
