Depending on how much of the tap is still in the hole and the size of the tap. I have had luck with simply taking a center punch and breaking the tap apart and getting it out. OR taking two pics and twisting them to spin it out.

you'll never touch a tap with a standard drill bit, are you on a bench or machine of some sorts?

all the above methods are practical depending on how the tap breaks, and yes there are several ways a tap can break lol

from the sounds of it, you need to get that head in a bridgeport or another machine that's just as rigid. i'm young but i've been a cnc bridgeport and boring mill operator since i was 15 at our family owned machine shop.

i don't even bother trying to extract anymore unless it's a rediculously easy one, you just end up screwing up the part you're working on.

MY ANSWER finally after i digress, is a 4 flute carbide end mill, slow spindle speed, very slow downward feed, and cutting oil. punches a clean hole through every time.

then break out the bits left after you get a hole through it.

use a tap extraction kit, will cost you about 40 to 50 bucks but will come with drills and pick to remove the tap. depending on what size tap you might be able to use a left handed drill bit and get lucky and get it to back out.

Remember will drilling hard materials low speed on the drill and use lots of lube.

This has worked for me in the past, make sure to use lots of air or spray lube to clean all the chips dirt and debris out of the hole.
