My son used my Bosch impact driver and got a square drive bit stuck. I've tried to yank on it with pliers to no avail.
Any ideas?

There's a review of that driver on Amazon describing that problem. If I remember correctly, the reviewer found a method to remove it that works.

Grab a hammer and hit the bit quite hard back into the chuck. After that it may come out properly. I had to do this on my dewalt.

Here's that section of the review I was talking about:
BEWARE! DON'T USE SHORT BITS WITHOUT A BIT HOLDER
My only complaint is that the collet has a significant limitation which is not well described in the instructions, and this caused me a big problem.
The instructions say the following: "The Bosch model PS41 Cordless Impact Driver has a collet that accepts only standard 1/4" hexagonal shank accessories with power groove." Well, ALL of my driver bits are standard 1/4" hexagonal shank, but I didn't know what a power groove was (isn't that something in a Michael Jackson tune?), and they offered no explanation. I looked closely at the standard 1/4" hexagonl shank bit I wanted to use, and it had grooves in it, so I used it. All went well until I tried to remove it: it was jammed tight, and I could not get it out.
I had to call customer service for help. "Is it a short insert bit that you inserted?" Yes. "The Bosch model PS41 Cordless Impact Driver has a collet that accepts only standard 1/4" hexagonal shank accessories." Yes, but I used a standard 1/4" hexagonal shank bit. "The bit would have to have that power groove on the shank. Otherwise, with the short insert bits you'd want to use a bit holder."
Great! Why don't they say that in the manual? And maybe tell you what a "power groove" is? Yes, there is a picture showing a short bit with a bit holder, but there is nothing telling you that you have to use it that way, and since you do NOT need a bit holder with the PS21, naturally I assumed that it was an option, not a requirement.
So what IS a "power groove"? If you look at a standard 1/4" hexagonal, two inch long screwdriver bit, just above the shank end there is a substantial indentation that goes all around the bit. THAT is what they mean by the "power groove". What I tried to use was a one-inch bit, and those bits NEVER have a power groove. To use a one-inch bit, you MUST use a bit holder with a power groove - or you will have a devil of a time getting that one-inch bit out again.
Do I feel stupid? Sure. But hey, I'm an amateur, not a pro: I read the instructions, and there's nobody around to warn me what was missing in the instructions. The instructions COULD have had an extra sentence like "WARNING: Do NOT use one-inch bits directly in this tool without a bit holder or it will become jammed and difficult to remove, potentially voiding your warranty" and a little picture of the one inch bit with a circle and a line through it. Some people complain about getting reconditioned PS41's- I bet these are returns from people who jammed the bit and just returned it that way.
Customer service may tell you to try tweezers or long-nose pliers to pull on the bit while pulling down on the collet. I tried: No way. Try this instead: get some narrow-nose vice grips. Clamp down on the bit just as tight as you can, releasing, retightening the screw, try again until you can't clamp any more, back off and clamp. Now put the vice grips in a vice, or clamp them to your bench somehow. Then while pulling down the collet, pull the drill for all you're worth. After a few tries, it worked, and no apparent damage to the tool (OR the bit), because it works fine now.
Now I own a magnetic bit holder for short bits, plus a variety of bits that don't need it. And you will too, if you read this warning.

The little maybe 3/4 of an inch bits (dewalt, etc) will go completely inside, and they ain't coming out ever again. Never. Ever.
You can disassemble the tool, but you will find the bit holder is a blind hole.

That happens frequently with my Dewalt brushless driver, and it happened with my old Makita. Just grab the bit with pliers, feather the trigger and slowly impact it in reverse and it will un jam.

Yep it happens. Like others said put it in vise and go foward and reverse while pulling retainer back and pulling driver toward you and it will come out.

Ive had that happen multiple times. Try smacking the bit down on something solid. Always works for me.

The only time I have ever had any issues with any of the impact drivers is if I use a non impact rated bit, they almost always get stuck.

So for those with this issue and have gotten the bit out, what is the mechanism by which the bit gets stuck inside?
A ball bearing is usually the thing that holds power bits in.

I have used mine for years and never had that happen to me

I had this happen to me and clamped the bit down to a counter top I was removing. IIRC I got the bit stuck while backing a screw out so I impacted it forward and the bit came right out.
So I assume the bit just twisted slightly inside of the chuck and the high spots of the hexagon got stuck against the inside of the chuck.
Impact is still working great, which is unfortunate as it would take very little for me to upgrade to a new system.

I have the PS41 and have never had this issue, used the hell out of it over the past 3 months. I only use Milwaukee and masterforce impact rated bits though.
