Broken bolt extractor

[saddlebum]

Anybody recommend a good one. The one I have aint working

In cases like this, the cheap stuff usually fail. I like the reverse thread bits from matco

 

[SlugSlinger]

These work pretty well.

How big is the bolt? Agree on reverse drill bits if you can find some.

You can hold a regular drill bit against a a spinning bench grinder wheel and make it reverse cut super easy.
It wants to sharpen that way naturally.. very hard to sharpen it to cut right hand.

Take a dull bit and try it. angle the bit into the wheel.
I save all my broken and dull bits just for this or i sharpen them for right hand which takes 4 times longer.

I do like the reverse cut for removing busted bolts.
A welded nut over the broken bolt works in some cases.

If you can get in to the area.
I have a 110 mig welder if you need and are not too far.

I weld directly onto the broken bolt and add enough material to get vice grips onto it and turn it. If I can't get a welder to it, I use a reverse drill bit followed by a spiral extractor (Hanson 11119). NAPA should have whatever you need to extract a bolt.

Got a picture of your situation?

Make sure the bolt isn't hardened before you try to drill into it. What kind of bolt is it, how big in diameter, and where is it located? As stated before, pictures will help.

We are visual learners/helpers and need a picture.

Snap On has left handed drill bits. They are the best thin g I have ever found to get bolts out. They drill and they torque out the bolt at the same time. Usually the bolt just unscrews as I drill.
