HELP! Bolt extractor broke off inside CAB bolt hole

[ebox86]

So im in a bit of a pickle. I had a bolt break inside one of the CAB bolt holes on the drivers side CAB. The one is fine but the outer bolt broke inside the hole. Well now after trying to extract it, it seems i've used the wrong size bolt extractor and now the extractor is broke inside the hole. From my readers, these extractors are made of hardened steel

Some people on other forums have suggested a bit made of carbide. I went to depot today to try their hardest titanium bits and the extractor just laughed at it.

Heres a pic of the damage



Any suggestions?

any particular type of bit i should get? Just a quick search on their site and found this :

I found these but wasn't sure if this would work, has anyone had first hand experience drilling into one of these?

Yep you need a solid carbine drill. And it should be a left hand twist as that may back out the bolt stub as you drill.

You could try applying heat and making a slot for impact screwdriver. Sears or a auto parts store should have it.

heat expansion will let the threads and bolt separate a bit.

if you decide to cut the welded nut out i think i have a good frame rail section with a good set of them in there. you could cut a hole in the side of the rail and air chisel them off weld new one and reweld and seal.

I think im going to try heat with a blow torch to try and expand it and then knock it loose, carbide bit is on order tho

thanks guys

Do you have access to a welder?

Could just weld a nut to it then use a socket or wrench to remove it all.

This.

I have had to remove several broken extractors. I would take a Dremel and try to get the extractor as flat as possible. Also I had a set of left hand diamond tiped drill bits.

Also if your using the twist style extractors, do yourself a favor and throw those away and get the straight flute extractors.

I had a similar situation, minus the easy-out breaking off. I drilled out the bolt, ground the threads off a stud, hammered it in, then welded the circumference.

Ran into the same issue last weekend, I got a beefy screwdriver roughly the size of teh whole, hammered it in, finagled the screwdriver into a 18v DeWalt drill and the bolt screwed right out with one punch of the trigger. YMMV, but it was really in there so I think that method should be a first shot

Drills are not made of titanium. Even if they were titanium it's not harder than carbide or regular drills. Quite softer. What you bought are just regular old drill bits with titanium nitride plating (that gold stuff on them).

I suggest you just try the welder method if you haven't figured this out yet. Carbide bits are very expensive and they chip and break very easy if you don't take extreme care when using them.

Take it to a shop. I broke off a front subframe bolt once, spent $200+ on tools, and ended up paying to get the bolt extracted by a pro. Same thing when I broke off the small bolt at the back of an M20 head where the water pipe attaches. Had to get it extracted at a shop. Broken bolts are HUGE pain in the ass. I feel your pain.

McMaster Carr - reverse-thread carbide drillbit so when you're drilling out the bolt it has a chance of grabbing and unscrewing it. Otherwise, it'll chew through the bolt easily. Penetrating oil before and during.
