I`ve been trying to get a broken M5 bolt out of a sub pump. Drilled a lovely hole, nice and straight, then noticed that the stud moved a bit in the hole. Time to use an easyout ,I thought, never ever use them normally coz I think they`re useless, but this was only an M5 and it did appear to be a bit loose in the hole. WRONG!!!!!!!!!!!!!!!!!!!!!! How the hell do I get a broken easyout out of a 4mm hole???????? Hole is too small to use a centre dot to break it up and there`s nothing above the hole to grab hold of. HEEEEEEEELP!!!!!!!!!!!!!!!!

OH BLAST. Not good. I did this a few years ago. I tried everthing from heat to freezer spray to get it to move. Its way too hard to drill so I bit the bullet and got it spark eroded. cost about £30. If all else fails spark it out!! I have never used an easy out since. They don't work.
Good luck.

only the second time I`ve used them as well. The pump`s not worth the £30 or the ag of getting it done. might grind a masonary drill to a point and smash the bugger with it.

If at first you don't succeed, try a bigger hammer!

"Easy Out" has got to be one of the most mis-leading product names ever!
I don't know anyone who's ever used one successfully -though we've all been tempted to try them haven't we, even though we know it'll end in disaster.

Here is what to do.
Get your tig welder out or if you aint got a tig then a mig will do. Place a nut of a larger size over the hole or whats left of the stud and carefully weld the broken bit to the nut. Once its cold use a spanner to undo it. You might have to repeat the process a few times as the nut sometimes breaks off but it will normally come out 2nd or third attempt. I use this method to extract broken nippes from brake callipers and I have never failed yet
Next time someone on Ebay pi55es you off send them the eazyouts as a prezzy or failing that chuck em in the nearest bin

what if the broken stud is below the surface???? Should have thrown them out when I got them as a "free" gift with a set of spanners, however I did use a larger one a couple of years ago and it did work , but I would only ever try one if the broken stud/bolt has some movement in it however slight. My fault for using such a small one I suppose.

I'd not heard of these tools before but from looking at some pictures on t'internet they look pants! Good luck with your M5 :S

 As hard as any known drill bit and when
it snaps off in a bolt you've got problems.
 
EASY-OUT, EASYOUT, EZ OUT, EZY OUT, BOLT AND STUD EXTRACTOR:
(AKA) Bolt Extractor, Screw Extractor, Bolt Remover, Stud Extractor, Stud Remover.

The EASY-OUT or bolt extractor tool by design can be a very useful tool for the removal of broken bolts and studs "IF" conditions for its use are perfect and preparation procedure are followed exact. Without going into when and how the easy-out or extractor will work I"ll give you some circumstances when they generally don't and reasons why you might want to try another approach.

For example a 3/8 inch bolt breaks when you are trying to remove it. The only reason a bolt or stud will break when removing is severe seizure. In this scenario the extractor recommended for removal would be 3/l6 inch to 1/4 inch in diameter. Most easy-outs are designed and manufactured using hardened material making them tough but also very brittle. In a this case the recommended extraction tool is about half the size of the broken bolt and three times as brittle, the easy-out will break practically every time.

In a case where the easy-out might have a chance for success, the steps for preparing the broken bolt are critical. For example, you have a broken exhaust bolt in the cylinder head on the engine in a car. The location of the broken bolt may be difficult to access, making the proper preparation that much more difficult. When drilling a hole for an extractor it is critical the hole is the correct size, perfectly on center and straight. In this situation a mistake in any one of the proper steps could result in the following problems:

If the hole is drilled to big, the extractor expands the remaining shell of the bolt defeating its purpose.
If the hole is the proper size but off center, the same result will occur.
If the hole is the right size and on center but on an angle to the bolt, the chance of drilling that hole into the threaded hole is highly probable.
In this case, the easyout can be driven through the side of the broken bolt into the threaded hole and become a locking device. Again, working against itself. Easy-outs extractors "CAN" work "IF the application is right and the correct steps are followed. The problems created as a result of mistakes like the ones pointed out above are as follows. Continuing to drill larger holes in the broken bolt when the hole is off center or at an angle will result in not only damaged threads and possible head damage but you'll still have portions of the broken bolt left in the hole.

Any steps taken from this point can become very desperate. You might try the ez-out anyway and break it, NOW what? Anger and frustration could set in, large hammers, chisels and maybe even torches come out and all rational thinking is gone. At this point the probability of success is remote and the possibility of destroying the head or manifold is very high. Besides the aggravation and the cost to replace or repair damaged parts there could result in weeks of wasted time from improperly using the ezy out extractor tool.

Save yourself time, money, and trouble.

Dont accept them as a gift and for gods sake dont buy them

sometimes, when you`ve done something stupid, telling people you`ve done it only provides them with the entertainment of telling you you`ve done something stupid. Thanks guys for all your help pmsl  ;D ;D ;D ;D

you want to try a set like these.they dont expand the stud when trying to remove

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=270695970675&ssPageName=STRK:MEWAX:IT

Is that just cos they say it in the advert or have you tried them?


(speaking as a failed ezi out user!)

no i have not used them. B G. but i know someone who has a set and said they work ok.a lot depends on how bad the broken stud has seized or rusted in.plenty of penetrating oil to soak at first then try and take it out with ease

I have a set like those, we have used that type at work for years, used correctly they don't break, and as said don't expand the broken stud/bolt

Used those one's myself in the trade for years and they are about the only one's I would trust....Voodoo......

the phrase horse bolted and stable door spring to mind here.........well from my point of view anyway lol ::) ::) ::) ::)

never mind... your  never to old to learn new tricks and idears  ::) ;)

this does not help- you at all cabman but

i think if there was a list of crap tools that doent work then second on the list would be

the nut spliter

this tool is strangley linked to the ezy out as you only really need it when you can get a rounded nut of a stud cause its seized on and you think , i know the quickest way to get that off is with a nut splitter- this is the wrong approach and will cause hours of endless frustration

 

aaahhhh!!!!!!!! now i`ve got two of those and they both work and have done so on a number of occasions. Mind you they`re not the cheapo Draper ones.

i used a similar thing to get a snapped stud out of reliant gear box mount. worked ok , been scrap i guess without getting it out. ok as a last resort.

I just had to look it up as I have used stud extractors before and they have done the job. Thought they must be something different but nope. Maybe I have been lucky cos they aren't an expensive make and are about 20 years old or more.

maybe the lesson to learn, if I hadn`t already, is that old tools are often the best tools.

agree with that cabman, we tried the Chinese generators that seem to be everywhere, look the same but crap metal. allways look for the older genuine jap Honda ones now. much more reliable..

Dunno Cabman, looking at everyone elses fun and games I think the lesson to learn is I have been lucky and not to use them again ;)

Did you get anywhere with welding a nut to the stud?

nothing to weld to, stud was broken just below the surface. I`m having a little bit of luck smashing it to bits at the moment, just doing a little at a time

after dismantling the pump a bit more I`ve found I can drill through from the other side and then, hopefully, hammer the bloody thing out from the back. How hard could it be???????  ;D ;D ;D ;D
