Quick question, I want to use pic related to remove some scratches

Swirls over a larger area won't come out very well with a drill, you'll likely make it worse. Small scratches would be okay with a drill.

You can get a cheap DA polisher off eBay that is unlikely to fuck your paint and will allow you to do a good job or the swirls.

I would use a flat pad, the softest you can get and grab something mid range like Meguiar's scratch X to start if you're intent on using a drill. If the scratches are really deep then move to Meguiar's ultimate, but only after you have tried scratch X.

Whatever you do don't get a rotary polisher if you don't know what you're doing.
I would highly recommend getting a DA or random orbital polisher instead of using a drill. You'll save time and have less chance of screwing your paint
