Any short bit "sinks", it is only necessary to press a little. after which it is almost impossible to pull it out.
Clamped in a vise and dragged with tongs - does not help.
For the first time, heating with a building hair dryer helped.
The second time - I found a thin long screwdriver and uprooted this spring.
I put a neodymium magnet inside, now you can use it.
Dissatisfied with the purchase for 3800s from the word at all.
