Chip hammer bit stuck in my post hole

I wasn't sure which subforum to post this in but I am building a fence so I thought I'd put it here. Out of 22 holes for my garden fence, 1 had a lime stone (I think) boulder.

So, I rented a chip hammer and started drilling and chipping away. Everything was going great, I was almost done, and then the drill but stuck.

It is a long bit and not in super deep, maybe about 7 inches or so. I've tried a pipe wrench but since there is so much bit on the outside, it just wants to bend around instead of turning.

Any and all suggestions are welcome!

If there is a better forum, tell me and I will see if I can delete or move it, thanks!

It's moved.

Chip hammer = hammer drill. Is this a big one like a jackhammer or like a large drill ?

You tried disconnecting the drill and turning the bit in reverse and it just bends ?

I'd release it from the jack hammer and give it a few whacks on the side with a sledgehammer.

It is not a huge tool, maybe like an extra large drill. I wouldn't compare it to a full-size jack hammer. Maybe I'd call it a mini-jack hammer. The guy at the rental shop is the one who called it a "chip hammer." Personally, I've heard a similar device called a "hammer drill" like you suggest.

Yes, I tried disconnecting the drill and turning the bit in reverse but it just bends around. About 2/3 of the bit is protruding from the rock.

As for giving it a few whacks on the side, it is too deep in a hole for the sledge to fit at all. Maybe I can tap it with a framing hammer or the mini-sledge sideways. This is somewhat far down at the bottom of a hard-won fencing hole after all!!!

Send us a pic. Maybe if we see it we might be able to come up with some ideas.

I have found you can get them unstuck by bending side to side or pulling while the hammer is running. Is it a drill type bit or just a pointed spike?

There is surely more than one chisel bit in the box, isn't there? Disconnect the one that's stuck and use a different bit to break the other one out.

Pull the bit out several times while it is cutting. It will help it not getting stuck.

If rental I'd say return the rotary hammer to save rental fees and just pay for the lost bit. Then rent a pavement breaker (AKA electric jack hammer).

Thank you all, but I broke the bit off in my attempts. Luckily, the rental guy ate the cost. We didn't sign any agreement so I doubt he had any leverage over me in the first place. But, I was prepared to pay for it anyway--lucky me and lesson(s) learned!

Not to be holier than thou, but I would have paid for the bit I broke and struck it up to a learning curve. No reason the retailer should have eaten something that was your fault. Cheers to the retailer.
