The Ikea Fixa 5-piece hole saw set can be used to drill a hole in a tabletop. I intend to use the smallest in this set. The table is too big and even though the monitor arm is quite long, it is not usable when attached at the perimeter of the table.
Ikea claims through a picture that one can drill such a hole by hand.
(0) I only need the smallest in this set. What is this actually called at a hardware store? (In my experience it's better to buy just what one needs and in a higher quality, than to accumulate a set—sets are invaribly of lower build quality.)
(1) Is it actually realistic for an amateur (with steady enough hands, but who uses a drill only once in a blue moon) to expect to lower a drill and the FIXA attachment, and get a clean hole? Is a drill arm lowered by machine (whatever these are called) necessary to get a clean job done?
(2) If I drill the hole by hand, can I expect to get a clean enough cylinder from the table so that a few months/years down the road when/if I no longer care for the monitor arm, I could reattach the cylinder with a bit of glue and recover a decent enough tabletop? It's understood that there is no way to make the result look like the original, but putting the cylinder back would be much nicer than fitting a piece of plastic cover right in the middle of the desk.
My main question is (1) above. If you can also comment on (0) and (2), please do.
I'm guessing that the "key advice" under this answer applies. One must first practice on a scrap tabletop.
