As others have stated you shouldn't have to bang it in. Simply putting into
the matching sleave so that it bottoms should be sufficient. If it spins
then its probably due to dirt of some sort either on the tapered shaft or
its matching sleave.

These basically work because it is tapered and the match between the shaft
and the cleave is very good.

Perhaps a silly question, but is there more to properly setting a drill
chuck or drive center with a morse taper, than to completely degrease it
an
give it a good whack with a wooden mallet?

Thanks,
