I would go for at least a 16mm bar, or even 25mm, provided it'll fit in your lathe.
And I prefer ones that take CCxT inserts.
I wouldn't be too bothered about brand, as there's not much to choose from with cheaper bars.

It'll also likely be worth making sure all the slides on the lathe are adjusted properly as well, as with that kind of overhang, any play will be magnified.

Depending on how much you use the lathe, it could be worth fitting a quick change tool post, as they'll also give a far more secure mount for any tools, than the bog standard tool holders. I've personally always used ones from Arc Euro Trade, so I know I can buy extra tool holders.


Regardless of all that, you'll need to be aware that even with the best setup, you do risk ending up with a tapered bore. A more consistent method for accurate boring on lathes, is to mount the workpiece on the cross slide, then spin a boring bar between centres.
