Easy Out Broke Off...

If you are drilling the stud out and tapping it, you will want to use a 1/4 bit or .272" bit. 1/4" is the most common. If you use a carbide tipped bit you will want to work slowely. If you don't you will burn the carbide off the tip. Start with a smaller bit to get started. Then gradually go up in size.

I have never used masonry bits when drilling out a stud and easy out before...
Alright, you tell him how to use a masonry bit, but then proceed to say that you have never used one in this situation before? I thought we went over this!! If you don't know what you are talking about, STFU!!

Allan, ban this n00b for a week, I will paypal you the money!

No, not all masonry bits are carbide. You want firm steady pressure on the masonry bit and use a LOT of coolant/oil on it.

Did you try the left hand drill bits? It is probably in there too hard now from trying to drill it out, though.

I'll resume working on it tue/wed till then I've been getting other things done.

I'm going to pick up the drill bits but w/the way things have been going, I've removed more material using a dye grinder than drilling. So either the easy out is still in there or the stud has become hardend due to heat or drilling (I'm just speculating here). I think that if I could get ahold of a good porting bit I can make a hole, then start drilling. If some one can referd me to any stores that sell such a bit that would be great, Northern might be my best bet though.

I have only been stating what has worked for me. All masonry bits we stock at work are carbide tipped. "I" would use a hard metal bit (cobalt) instead of a concrete bit (masonry). Just my opinion. Stay OT.

If you are removing bits, you are headed in the right direction. Odds are that your die grinder spins quicker than you drill. You could try putting a bit on the die grinder if you want or a rotozip bit.

The problem is that the EZ-out is harder than the cobalt drill bit! That is why EZ-outs are so brittle, because they are so hard.

Don't use a porting bit though, you will want to use something much finer. A porting bit is made for softer metal and will just burn up against the EZ-out (just like the cobalt drill bit above). I would suggest staying with the diamond tipped bit.

Just leave the fucking stud in there,it's not gonna do much harm missing one bolt on the manifold. You'll have the head off sooner or later and when you do take the head in and have them cut out the bit, weld the hole shut and redrill and tap it.

Well if anyone cares, I picked up a carbid burr remover. Grinded away the easy out w/no problem, re-drilled the hole and am going to re-tapp it. Thanks for all the suggestions everyone!
