this looks like it's two pieces

if it is two is it possible to separate them




So there is the mt taper for going into the spindle,
and then they is usually but not always a J taper or sometimes other
tape for the MT arbor to the chuck.

There are wedges used to pop them apart. You can buy the reasonably.
They are meant to remove the part w/o destroying the chuck. The
pressure is put on the landing around the abor, not on the moveable ring
that tightens the chuck.

I think they can be had for around $16 ..
