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.
