Happened to a mate with a TD5. Broke two easy-outs, got a specialist in and about 2hrs later they were out. The guy sharpened the drill bit about ever 45 sec.
So, it can be done. All you need is the right people with the right skill.
Cheers, Jurgens.
X 2 As a metal trades person, Tool maker I know you are not going to drill a easy out.Quote:
with a very sharp requenched chisel see if you can tap it in the normal direction of do up and work it out...
gently warming the whole area then quenching the eazy out with freeze'n'release may help
failing that its time for spark erosion because really, you cant drill an ezy out.

Soooo... I just purchased some stud extractors to use on broken bolts in my turbo hot side housing. This thread makes me think that's a bad idea? Heli coils perhaps?
Keenserts are superior to helicoils in most cases, Keenserts are a more permanent repair, particularly when future disassembly and reassembly are likely.

I must have imagined it then;)Quote:

Ive had plenty of success with them...
you need to rigidly adhere to the 6P principle
They can be used, however only when a bolt or screw has broken from over tightening.
Anytime you try to remove a something that has broken from trying to remove it is going to end in tears. Especially when exhaust related.
The rigid brand that aren't tapered and are knocked in work best.
I make my living fitting 4x4 accessories and before that I was a marine engineer for 8 years and in my own experience easy outs are great.
The key thing with easy outs as with any other specialist tool is to follow correct procedure and if you are breaking easy outs etc then as mentioned above, your best bet for damage limitation is to get someone who uses these things every day to help you.
You can drill absolutely ANYTHING with correct combination of drills, technique and patience.
If you have access to a heat source with a very precise nozzle you could anneal and drill the easy out a little bit at a time but you'd want either cobalt drills or diamond tipped/carbide tipped ones.
Whatever you do be very careful because if you slip while drilling then it's a job for. A really competent welder to fix the mess.
lime can be your friend if you have a broken tap, drill or ezyout in an object you can pack it around to slow down the cooling rate.Quote:

leave a few hours and then using the hardest drill you can obtain and cutting fluid such as rocol or trefalex you can use the drill at a much slower than normal speed to erode / remove the object of your attention.
certainly not suitable for all occasions but it can be a life saver at times.
