Tool to hold cylinder from the inside

Whats the ID.
My advice would be to make a small jig.
10mm threaded bar will fit into the drill. If it will also go into the ID of the tube then all you need to do is make a spacer With a 10mm hole and either a lip or taper to the true ID of the tube and use bolts to hold the tapers to the tube.
It's called a spool clamp. And if all you are doing is polishing then you should be fine. You may want to make a support for the free end.

What tooling do you have available, only a drill?
On a lathe you'd probably hold it internally one end in a three jaw, its only short, 10 minute job. Attaching it to a little drill is going to be challenging, two discs and a bit of studding/nuts?!
/edit The spool clamp thing looks good above if you can buy it, if you have to make the spools you'd have a lathe and will have just done it the easy way.

This. Don't even waste your time, getting it even will be a massive mission, and it's a job that will take 5 minutes on a lathe.
