Good afternoon my friends
So I may have bungled a bit on my custom top-cover by sheer over enthusiasm.
I drilled all these and was confident the holes would be shard and clean on the upper side, but the all have that tiny little sharp burrmaking it looking and feeling a bit rough.
I want to have them clean and, well, somewhat shiny, but don’t want to make the countersunk by ≈ 1 mm…
The tool I use tends to not bite unless I press so hard that it instantly cuts off too much material.
What should I use? Something to go with a very simple table-drill, or just a hand-tool?
(I was thinking of something that would rather grind than cut, but it’s 2 - 5 mm diameter…)
As you can see, this particular plate already is, erm, failed, but nevermind I fine if I can improve it (better than starting over, right?)
Thank you!

Try a countersink bit with more flutes or cutting edges. Some have 8-10 and produce a cleaner cut.
Ja, and mount it in a hand chuck, since it's just soft aluminum...

The job you did isn't bad at all IMO, and if that cover were mine I wouldn't touch it anymore.
Since you have (rightly) decided to paint it, I would give it a couple of coats of emery cloth of at least a couple of different shades to eliminate those (small) burrs and then I would repaint it.
In my opinion it would be great!
