Broke off and EZ out in a bolt. Tried a couple of drill bits and was reminded that the EZ outs are verrrrry hard steel.

Anybody got any help on how to get through a broken off EZ out?

I broke one out a couple of years ago on a thermostat housing in a Volvo I/O. Bought a diamond bit I think from a hardware store. EXPENSIVE, but it worked. Ended up with a larger hole than started with so rethreaded the block for a larger bolt.

Good Luck,
Wayne

Thanks Wayne, havent seen diamond bits, so will go looking. The other alternative I have found on line is some kind of electrical machine available at machine shops. Problably more expensive that the bit.....t

This may not help, my girlfriend sells diamond core bits for cutting glass.
If you can give a diameter of the bolt and depth, she might have one.
Thanks, Don.

Try a left handed drill bit, it actually cuts in the reverse direction and would have probably gave you better results than an ez out a lot of times bolts will back themselves out while you are drilling thru them.

Ez outs works good some of the time others times they just cause a lot more problems sometimes if you have the room you can weld a bolt to the original broken bolt and work it out also

Its flush, no room to weld. Found a diamond drill at lowes, and tried it, might work if I could drill for a day or two.

Don, if your girlfriend thinks her bit might be more agressive, a 5/16 bit would probably do it, 2" max...let me know.

Otherwise off to the machine shop...thanks for all your thoughts..t

Makoman, She doesn`t have one that deep. Around 1/2 inch deep. It might be to the machine shop for you. Thanks, Don.

If you have a stick welder sometimes you can just stick the rod to it without arching.. This will do 2 things it will heat it red hot and loosen it and it will take the temper(hardness) out of the ezee-out then you can use a center punch..

I would try the center punch method until I got the EZout below the surface. I would then switch to a bolt extractor designed to work in a drill. They are similar to a left hand drill bit except they are designed to grip not drill. they are harder than steel but softer than the EZout.

Thanks, will try that first, a little nervous about the red hot and what it might do to the rest of the unit. One issue is that the bolt is in a free spinning unit, and the access and ability to grab and hold the unit is about 1/8" in width, so not much grip there when trying to spin out. Appreciate all the interest and thoughts...rather be fishing...t

I have never seen an easy out you could chip out, I have seen taps broke off that you could chip out a piece at a time with a lot of patience, if you could put up a picture we might be able to help you a little more.

You need to look for a shop that has an EDM machine.

It works alot like a welding stick, but its not.

GOT IT!

Middle of the night inspiration..remembered those tiny grinder stones for the Dremel. Wore out one, got it on the second one. Much faster than the diamond drill bit. Thanks for all your advice, one down...t
