That little 8mm stud in the exhaust manifold snapped when I pulled my turbos. I know I need to buy an EZ-out or somesuch stud extractor tool and left-hand drill bit, but I'm worried my drill won't cut it.

Will my cheapo Black&Decker hand drill have the torque to get it loose? (It's a plug-in version, not cordless). I wanna get this done tomorrow, and if I need to borrow a bigger drill I need to know.

An EZ out probably won't do it since the stud is so stuck. You'll have to actually drill the stud out and then chase the threads. If you hurt the threads don't freak out, just use a Helicoil.

The studs drill out easily enough with a good sharp bit and some cutting oil.

 

it may be easier for you to remove the exhaust manifold and take it to a machine shop. Not doubhting your ability. Just like Damon said though. It is most likely going to have to be drilled out. This will probably burn out your B&D plug in

Also the machinist can chuck it up and have it done in about 20 minutes. My machinist is used to the turbo studs breaking now that it is a wait for it deal now

If you want to attempt it yourself still. Then i suggest getting a stud removal tool from snap-on or other name brand. The eZ-outs tend to snap off when any "real" torque on them. The real tool has a barbed/ridged shaft that gets wedged into the hole drilled and has a base "collar" to keep it steady. Also comes in about 10 different sizes. you will still need left handed bits and a good drill motor.

In the end it is usually cheaper and quicker to use a machinist. BUT you get to wow everyone with your vast mechanical vocabulary when you do it

POSTED BELOW ( By Kento) is the BEST info for anyone trying to drill out any stud or for that matter drilling in general. Lube is the key to your expensive bits doing their job!

 

And be liberal with the cutting oil when drilling. Nothing blunts a decent drill bit faster than a dry cutting medium.

 

I tried using the Sear/B&D stud removal bits. They are two sided where one end is a drill bit, and the other the stud removal tool, that you apply in reverse.

I broke 1 on these on the 10mm T-Stat housing bolts.

I wouldn't recommend them.

 

Ive used a little torch to heat around the stud then a reversed drill bit and a cheap air drill, it takes a minute to catch and then it just screwed out like normal...

 

Thanks all. I'm taking it to a local shop tomorrow morning (too late in the day today) and having them do it. I'll wait until I have a garage with a drill press or air tools to try it myself.

i brought it to a shop......i spent 40 (yes 40) on drill bits once trying to get a stud out of the manifold........

use a 3/4 Stud Removal, that's what I use to get my Stud out from the manifold.
