drill bit stuck in drill

I have a Hypertough brand hammer drill I have owned for the past three years. It has seen occasional use, and has done a great job, and not very expensive:

However, after using it with a 1/4" bit to drill into some masonry yesterday, when I went to try and change out the bits, the bit was stuck. I tried using a cloth around the keyless part so I could get a better grip, but still stuck.



I also tried to use the same technique as the man here:

However, all holding pliers around the chuck does in my case is stop the chuck and does not free the bit (with the motor heating up fast!). At a loss as to how to proceed. Like in his video, at around 53 seconds, the second piece of plastic in mine also spins around. I think I warped something trying to get it freed yesterday. Taking the drill apart I see the chuck attached to a gearing. Unfortunately, all chuck replacements I see online just show the chuck with no gears.



Before I just go buy another one, I thought I'd see if there was anything else I could try first. Thank you in advance.


Squirt some penetrating oil in there, Put the biggest vice grips you have on the chuck and smack it with a hammer. Keep that chuck lubricated in the future.

Not sure how to do this. Both parts of the tightener spin freely (in other words, if I try to tighten or loosen, the rear plastic part is also spinning). I tried pliers on both parts yesterday, but all that accomplished was a freely spinning rear plastic part just like at 53 sec in the video.

Would be great if I owned another drill, but do not unfortunately.

It should be spinning against the inertia of the motor and a sharp impact will crack it loose. Just be sure you are spinning it the right way.

It's pretty much junk the way it is. Break off the plastic and dissassemble the chuck. Many have an allen screw up in the center (particularly reversible drills) - when the screw is removed the chuck can be removed. Some are just taper mounted - some are screwed.

The lock screw in the center of the chuck needs to be removed before akeyless chuck can be removed from MOST reversible drills. The screw is generally a left-hand thread.
