You ain't going to drill it out. If at all possible take the part to a professional.

I broke one off on a Flathead Ford one time....managed to weld a nut onto said piece and slowly backed it out with a wrench. Best done while still hot.....
 
What I have done in the past is to grind the broken tap as flat as possible and start a small hole with a carbide tipped extraction drill. With the hole started see if you can carefully grind out what you can(a Dremel Moto Tool works well for this job).Then with a small sharp punch break out the rest. Grind a flat , drill a little and chip. I doubt that you can get in there with a tap extractor so the chip away process will be necessary.
 
I don't think you can find a drill bit that will touch a tap. A steady hand and a torch is how I have removed them.

You might,might, be able to use a Dremell tool with several diamond bits. I have done done this with bearing races and other hard metals. But have not tried it on a tap. May or may not work.
 
How's that old saying about two tools go?
Duct tape and oil. If it doesn't move and it should, use oil.
If it moves and it shouldn't, use the tape!
So just tape the seat down and you're good! LOL

If it's an extractor it should have been threaded in left handed.
Depending on the size you "might" have a chance at turning it
the other direction with a small punch/chisel and hammer.
If you can get that out you're only left fighting the bolt.
At least it's not as hard as an extractor or tap are.
Good luck amigo!
 

Torch it out BTDT it amazed me how EZ it was to do. The tap heated up QUICK like in rat now pulled the trigger and it blew apart the tap, cleaned up the mess it did not damage the hole are threads at all :shock:

I have done it about every way suggested the only thing I see bad about busting it out is if its a blind hole you mite bust the bottom out...

Before I read about the touch trick I got a hold of this engine with a broken tap in a head bolt hole. They had fudged it up bad with a drill bit. I used a high speed carbide bit and got it out but oversize the hole they had already oversize... This repair worked great...

I worked in a power house softening water and making steam. Our sodium softeners were large cast iron castings with rubber bladder valves in them held with a flat cover with many 5/16th cap screws holding them to the unit. We seemed to break a lot of them and blew them out with the torch. I've done the same with a Ford truck manifold. The first time is a little scary.

Burn out the steel bolt, or tap then run a tap to clean the threads.
