Snapping a bolt of is not a good feeling and I recently had this problem and to begin with tried an Ezi out to remove it. The kit was cheap and the Ezi out snapped , my mistake. Rob400 told me about left handed drill bits and Teknik has also talked about them.

Here’s a vid on using left handed bits to remove a bolt. Any other suggestions ???

I have seen them shattered with a centre puch successfully a few times. Depends on the size , how much is left in there and the substrate it is stuck in as well :whistle: :pinch:

I’m with you Eags. :kiss:
Have also smashed them out using all kinds of chisels/punches. :whistle:
Never have I tried to extract something of 6mm or there abouts. :pinch:
Good luck with it Nick. :pinch:
You will beat it though. Eventually.

P.S. Don’t ever try and take me up on that little. :kiss:
May have to try your bike out on grade 5 stuff.
You would have to be the pilot though. :laugh: :laugh: :laugh: :laugh: :laugh:

Patience is your best friend if the easy out is broken. Patience and a very strong Tungsten Carbide left hand drill bit, usually they come with an easy out kit made by sutton/P&N (I think :dry: ) if you have the option of a fair bit of metal around where the bolt is and the location is raised a bit like it was when I snapped a bolt then an easy out on the inlet for the oil return pipe on my XR400 you can use a thin cut off disk like on a dremmel and turn the broken bolt into a flat-head grub screw. But you can only use this method if the surrounding metal isn’t too important (ie you couldn’t really do it on your engine case.

Good luck :unsure:

Great tip their Bulls wool , I actually ended up just drilling out the easy out and most of the bolt to just under the alloy thread so it could be heli coiled easily. I will be using a left handed drill over an easy out from now on though

I like your way of thinking, Bulls Wool.
Have used this method many times at work.
Not with a broken ezi out, but, Could possibly be a goer.
Have used this method with stripped out allen head bolts/plugs.
Just be gentle, remembering that the ezi out is made of hardened steal and could quite easily break when pressure is applied to the screwdriver. :ohmy: :huh:

Best tip I can give here is if the bolt has broke because it is locked in the threads the chance of getting it out with an easy out is very low.
Take you time and drill out the bolt even if you only keep going up one drill size at a time it is still a whole lot easier then trying to get a broken easyout out.
Through the easy outs out of your toolbox all together
