... then the easiout taper can actually spread the remaining metal making it tighter

Which is why you drill the smallest hole you can get away with ...... obviously the smallest Easy-out isn't going to remove a 1" BSW bolt

ok, so its clear i shouldnt have updated tonight, not a lot of love for the easy-outs 

why do they snap? speed of use or just shit quality?

No but folk have tried it,honest,then wonder why it didn't work

There are plenty of shite quality but you have to know what you are doing even with the decent ones and even then it can go tits up.

As above. I've actually had better results with the type designed for screws (like a reverse countersink) and you can be more forceful as it isn't going to snap in the stud

If a M8 bolt shears because its too tight/rusted in, an easi-out made from 4mm hardened steel isn't going to do much, except fail.

I broke a die yesterday (die creates a thread on a bolt, tap creates thread in a nut), cleaning up a damaged thread on a TRE.

 ......

As above .... HTF do you manage to break a die?    (split die or die nut?  )

Split die. Part way through cleaning the thread up, when it hit the distorted bit of thread, PING!

Split opposite the split.

on the subject of repairing threads................. whats the point?  surely a replacement bolt is easier? i appreciate that on ''special'' bolts like exhaust bolts it may be necesary?

because as said, if the bolt head has sheared then it was f...ing TIGHT! And some stud extractors aren't Easy-Outs & are cheap & therefore will snap.

Depends where it is/what it is ....... and whether it'll snap when you try to remove it. And how do you get the Easy-Out of the broken stud etc etc 

Sometimes, just cleaning the start of the bolt will be more than good enough.

Still got a set of easy-outs from my Toolmaking days. I slated them for years but have used them twice recently with success. Removed a damaged Allen bolt from a diesel pump, where it was recessed and no access for grips, by tapping easy-out in to Allen head hole.

Like all tools, they have their uses. Just got to be sensible about where you use them, otherwise you'll end up in a bigger mess.

a) depends if you have a replacement for said bolt
b) in this case it was the tapered part of a track rod end. Rather expensive to replace track rod end, just for a bit of effort of tidying up the thread...   ...even if it did break the die

It wouldn't have just been replacement of the track rod end, it would need to go for alignment afterwards as well.

Don't forget that there's also a thread file available in various flavours of metric & imperial http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2047675.m570.l2736&_nkw=thread+file You'd use one where just one side of the bolt/stud has been clobbered & damaged.

Well, bit of a wasted day for me I like to move on but today I was ''floating'' helping others out as I was finished being assessed.

However I did hear some info that I'd like to discuss with you girls 

One of the lads reckons you can buy, although expensive, an impact gun that runs on cordless battery thats just as powerful as a compressed air impact gun.

I would really like to get one if thats the case as if i ever end up doing exhaust work and heavier work at home i'd like to be able to use it..... BUT is it as powerful in the real world as a compressed air tool?

heres what i found.... not sure this is what he means?
