I've bought a new 3/8 keyless chuck for my B&D drill and even before I
can find out that the new one is the wrong type and doesn't fit I'm

tighten very well and works loose).

I've removed the screw from the chuck, where one inserts the drill bit,
but the chuck is still very tight etc.

Once upon a time, you had to remove chucks regularly to fit attachments.
And the recommended way was to insert the chuck key and hit it with a
hammer...
