You can push that donut out with a mandrel and then turn it off, I would highly recommend NOT trying to neck ream with a drill, they will not self align until at least they are in the neck aways and then it will be to late,..the brass will be ruined!! You can use the reamers though, Get yourself a Wilson case holder that will hold your case, wrap paper or emery cloth around it and chuck it up in a lathe, put the ream in the tailstock chuck and you will be able to remove your donuts, after doing that I like to use steel wool or Scott's brite and polish the inside of the neck, make sure you remove all brass and steel wool from inside the case before reloading.

Thanks. I have the little do-dad from 21st Century that is designed to be chucked up in a drill and then there is an o-ring that seats in the primer pocket. You hand tighten the locking collar. Can I presume that this will work to chuck the brass in the lathe? I am also planning on sizing the brass before reaming the necks as well.
I have a 21st Century turner with lathe. Since the turner arbor does not have a carbide cutter like the K&M, I contacted John @ 21st Century. He told me that he uses a reamer in a drill press to do the inside of the case necks. John said to order a reamer .001" larger than the bullet diameter. I agree with you Wayne, that trying to ream the case neck that way will ruin the brass due to misalignment. I have ordered a reamer now that is .0005" smaller than the one John recommended. It will be here tomorrow, but I am not confident that will work yet either. I have invested a lot of dollars in the equipment and still do not have the answers. I find that following the initial expanding of the neck, there is always a small amount of brass near the bottom (inside) that needs removed. Perhaps using a lathe as you have suggested is the answer. Problem is that I do not have a lathe and I expect most casual shooters do not. I do like the carbide cutters ground to the case shoulder angle of a particular caliber that 21st Century sells. It just seems there has to be a better way to deal with the inside of the case neck. Perhaps I am too fussy, but I want the inside surface of the neck "true" and smooth. The only thing I can think of would be a reamer with a pilot at the bottom and no fluting until about 1/4" above the pilot.
