Could you shatter it with a punch? They're fairly brittle.

Can you weld a nut to it? If all else fails, curse and throw a wrench.

How big of an ez out?

I managed to tap one back out with a chisel a couple weeks ago, more or less tapped it so it would spiral out instead of spiraling in.

lol that is exactly what i would do
The spiral ez out is in a grade 8 bolt. The bolt is a 3/8-16. The bolt broke flush with the surrounding steel plate. The ez out is broken flush as well. I keep reading about these bits that will drill through anything. They are:

has anyone ever had any experience with these drill bits?

Wow that *****. I broke a Snap-On EZ-out in a a spindle, and I am a mechanic and had to have a machine shop get it out! Good luck!

From my experience, you are probably going to end up getting out the torch. An E-Z out will make short work of destroying any drill bit known to man.
Normally I'll get a small tip (like a 00), blow the bolt and E-Z out out in one shot, then redrill and put in either a Helicoil or Cat insert.

Whats a cat insert?

Cat inserts are solid sleeves with locking posts, like this:
I don't know who the OEM is, but we buy them in kits from Caterpillar.

I see... one of the guys at work was talking about something that works/looks the same way. Interesting.

They are basically a masonry bit. I bought a set, and they didn't hold up well. I found a vendor at the fair that replaced them, but he wasn't too happy about it. Don't waste your money. If you can get the item to a mill or drill press, I would try a cobalt end mill to get it out.
I hate ez outs. I've been in the same boat, and did manage to finally drill it out, but it took a long time.

A small center punch works well. They break pretty easy.

I would use a narrow diamond or carbide burr.

I had a similar problem the other week, except it was a tap, broken off flush. As others have said, a center punch will shatter it, then you blow some air and pick the pieces out. I found this out after ruining three drill bits. They can't be drilled. Good luck nonetheless.

never tried a burr but we usually very carefully blow it out with a torch like the other guy said.....boss man did it a few weeks ago on a exhaust bolt on a cylinder head....still in the truck....funny thing was I worked on the same model and year truck with the same side but different location and he was like "you better not break that easy out in that or its gonna ****"....then what does he do a week later on the same thing......breaks an easy out like he told me not too. lol I thought blowing it out with the torch like that was gonna lead to him saying "opps now you get to pull the head" (even though it was his project) but it worked perfectly....I'm sure I wouldn't have been able to blow it out without destroying the threads or blowing a hole into the water jacket.....lucky basterd

Actually, drilling a hole through a broken stud or bolt and then using a torch to melt/cut out the remains is a common method of removal. It takes a lot of skill, and works better in cast iron than steel. I have seen guys do it successfully in a steel part, but it is WAY too easy to damage the internal threads for me to try it. I have been successful in cast iron.

I don't even try any more. When I try to drill and easy out a broken bolt or stud I just make things worse. Off it comes and it goes to a machine shop.

Welding a nut will work if your careful. I recently had a similar incident on a body mount bolt for a sway bar. Also broke an ez-out off in in first. Probably a M6 or M8 bolt. I ended up plug welding a nut over top. Link below of the thread about it with pics. You dont need to be a good welder to pull it off, just try and stay more in the lines than I did, lol.

I've always broken them out with a center punch or chisel. Though depending on the situation sometimes it's worth the money more than my time to replace the part.
The torch is my go-to for removing broken bolts anymore, if you're good with a torch it's easy to do in say an exhaust manifold. Though I have run into a few that flat wouldn't burn out cleanly. If you do it just right, you just have to tap the manifold to get the slag to drop from the threads before you re-assemble, at worst run a thread chaser through it. At worst, you junk the part or like the time I was dumb enough to try it on a thin steel manifold, you're thankful you took the heat shield off first so the fact you blew a giant hole in it then welded it up wasn't really noticeable.

A 3/8 bolt. Weld it. With all due respect, IDK why this isn't common practice. I've had my fair share with taps and helicoils...that's for the birds on the bigger stuff (unless were talking delicates).
Weld a nut and crank that baby out.
I have cut them out with a tourch but it always scares me.I have also used
a tool mabe to drill out spot welds it is like a small hole saw [made by blare i think]
you take out the center and the ezout centers it and acts as a piolt.They come in
small sizes so you can do a 3/8 bolt.once you drill around the ezout you can pry it out
or tap it out then you cab drill and tap the hole to the same size.

I've had good luck with left-handed drill bits. They are expensive (as I recall about $10-30 depending on size) but work well. Ever time I've done it they bind and spin the bolt out before I drill through or even far into the sheered off bolt. Go slow and use oil.

Some engine repair shops and a good number of machine shops have a machine that will get the broken drill/Ezout/bolt out with no damage to the part itself. The hardness of the broken off piece does not matter.
Sorry, I do not know the correct name in English, but it works like this.
The part is submerged in a liquid. A nozzle with a wire fed thru it is centered over the middle of the broken drillEZout/bolt/tap or whatever. Power is applied and by electrical erosion the broken part is removed. (The swedish name translated is "sink-spark" which is of no use whatsoever
)
Piece of cake for a skilled machinist and the machine come in many different sizes. I have seen them as big as a small house for production drilling of extremely hard steel parts, but also the size of a medium sized drill press.
