SDS bit stuck in Ryobi drill

JMR

I have a 6mm masonry bit stuck in my Ryobi ERH 750v hammer action drill.
No amount of brute force has been able to open the chuck, any ideas?
Alternatively, does anybody know where a replacement chuck might be got, if that's the only option?

Picture attached in case any of my terminology is incorrect.
Thanks

That looks like a chuck for ordinary as opposed to SDS bits.

Is it an SDS bit inside it?

If the bit has jammed in, I'd have thought those collars would undo in a vice and mole grips or similar.

Yes, it's a chuck for an SDS bit and it's an SDS bit that's stuck in it.
I haven't had it in a bench vice but a pair of vice grips didn't shift it and i was afraid of damaging it.

Looks like an sds bit stuck in an sds adapter lol

I had those plastic adapters before, they do get stuck alright.maybe some spray and a vice

It's an SDS adapter then?
It did come with the drill when bought.

If I can't loosen it, can these be bought anywhere?

Ya they're easy got, but get the steel type

Those you have get jammed

That is a steel chuck, allows you to use steel hss bits with an SDS still,

If you have an sds drill and am sds but, then you do not need to use it.

Looks like you’ve put an sds bit into it, if you have a pipe grips that should be able to open it, if not you’ll need to stick it in a vice

Thanks for the replies.
It could well be a HSS bit that's stuck in it. It's been like that for ages, since it was returned after being lent out to a mate.

I'll have another bash at it with a pipe grips.

If that fails, what exactly is the part I should be searching for?

Keep spraying it. Leave it soak and spray again and a few times more. Worked for me.

Apologies if this is a stupid question but spray with what? WD40?

That's what I used, but somebody may know of a better one.

No it’s an sds but that is stuck in an adaptor that is not meant for sds bits,

If you put the entire adaptor into your drill, hold the bit in a vice or with a pipe grips, turn the drill on, you should be able to loosen it

Have ye tried a bash with a hammer? Seriously; With a traditional chuck, stuck, a sharp tap on the 'nose' usually sorts it and they open good as gold.

That's definitely an SDS bit in a 3-jaw keyless chuck.
As the SDS bit has 4 slots on the shank, it's almost certain that at least one of the jaws of the 3-jaw chuck is lined up with one of these slots, thus introducing a crooked load into the tightening mechanism of the chuck.
Add a bunch of vibration from impact drilling, and the chuck is now well jammed.

It'll almost certainly open with the judicious application of brute force, but it's tricky to do this to a plastic chuck without wrecking it.

I would say two strap wrenches working in opposite directions would be able to shift it.
I am sure you can buy them from Ryobi as a spare part but I don't know how much they would cost.
The issue you have is that the drill bit has been fitted to a chuck that is not intended to hold that bit.
The drill should take the SDS bit with no need for that chuck.

Not exactly expensive to replace https://www.amazon.co.uk/Hitatchi-Power-Tools-711099-Hitachi/dp/B00H3JZV3C/

You could spend more buying tools to fix the old one.

Removed one from a friends bosch, he had done the same thing. Into the vice two wraps of the hammer and it popped out. No problems.

If you have the tools, ie; vise or pipe wrench, and a vise grips.
Secure the chuck , fixed and movable part in vise/wrench,
Vise grips on bit and a couple tugs clockwise ,that is in the drilling direction,
may need a couple of taps.

It'll seize again though at later date

If it's auger or masonry bits it's better just to use sds bits

Steel bits use the metal chuck adapter

It probably will if you use an sds bit in it.
But why would you?
The sds bits go directly into drill chuck, no need for that adaptor .
