Solid carbide, Nate. Actually an end mill is a better choice, assuming
you've got a milling machine handy.

You have to be kidding. Have you ever even set foot into a machine
shop?

Videos are cheap to make and post. Show me a tap that you can drill
out. Then mill one out. This should be easy for you. You have said
you've done it many times.

I've set foot in a machine shop every day for 25 years, but I'm not
going to make a video to prove it to you. I'll assume that means you'll
choose to continue to doubt me. That's fine, but if you aren't aware
that solid carbide can cut through a tap, I'd say you're the one who's
only peered into the window of a shop on your way to whatever it is you
do.

Google something like "remove broken tap" and you'll see all manner of
references to drilling or milling them out with carbide tools. Maybe
you'll even find a video.

Solid carbide isn't something that most people are likely to have laying
around, nor is it easy to purchase except through an industrial supply.
Nor would it likely work well chucked into a hand drill, as I'm given
to understand that it's pretty brittle.

I don't have a milling machine handy... I wouldn't mind having one, but
the cost involved (and the additions to my garage) make the cost a
little steep...
