Jammed SDS bit

[ban-all-sheds]

Well - not actually a bit, it's a chuck adapter, but the principle is the same.

It's jammed in, and won't come out. Any tips for removing the thing from the SDS+ chuck?

Penetrating oil?

Been trying that.

On closer inspection, the problem might be more serious - I don't think the collar moves back far enough to release the shank.....

Ban all, when I had that a couple of years back it was a trip to the local tool shop and got it sent away. Sorry man.

Well - it's a Bosch GBH-4, so hopefully repairable.....

Always grease your end before you give it a good pounding boys

hold the release back and hit out with a hammerone of our drills does it all the time with a SDS+ adapter

Have you got the main chuck off the drill if so do as has been said hold back the relase sleeve and knock it out from the back with something suitable.Remember to lube your chuck regularly it really does make a difference. It is possible you may have displaced one of the ball bearings in the chuck hence it is jammed it may be possible to repair it if this is the case, but i have found from past experience, that once this has happened it will be prone to happening again.
A new chuck only costs about £25.

It's the old RTFM problem, I'm sorry to say, and thanks for the advice and sorry to have wasted your time and I'll get my coat...

What I thought was an adapter stuck in the SDS+ tool holder, like this:

(only mine is keyless) turns out to be a complete replacement for the SDS toolholder. So to remove it you don't pull back the collar and pull out a thingy with an SDS shaft on it, you grasp and twist what looks like the collar, and the whole thing comes off.

Like this:

Even though I said thanks for the advice, I'm glad I didn't follow that which said to hit it with a hammer...

Same problem with me, brand new as well, took it back to the shop, they made a few banging noise in the bench vice, since then it been alright. Sorry didn't see how they did it.

Ahh, didn't see your post! I try and remember that one.

lol. its easier if you put it in hammer only to get them out - stops it turnin so you can turn the chuck loose

Once I RTFM'd, it came out as easy as pie...
