Does this allow for quick rotating from landscape to portrait, or does it require tools?

Just don't tighten the nut down all the way, and check it periodically. I rotate my 23" monitor in and out of portrait/landscape mode at least once a day, and abuse the heck out of the arm itself by constantly pulling it in and out of position. I basically only pull out the arm if I need the second monitor, put it back away to clear the space and talk to someone at my desk, pull it back when I go back to work, then rotate it to landscape at night when I want to relax, playing a video game. It gets put back to portrait when I put it away entirely for the night. Once or twice a year I check and tighten anything that's gotten loose. Seriously a nice mount, keeping in mind that mine is anchored to a solid-wood pine hutch on my desk, rather than sunk into drywall. (And, yes, I realize this question is old, but maybe it'll help someone.)

I don't have a 4mm drill bit, nor does any of my friends. What size drill bit can I use instead?

4mm / 25.4 = .1574" so a #21(.159") standard drill bit would work.

Does this pull forward after a while from the weight of the monitor?

I had mounted it on the side of a kitchen cabinet over our bar and had no problem with it moving in any way. My wife positions it when she is in the kitchen while doing odds and ends and has no problem with it staying in the position she has selected. We love it.

What size of screws does this come with? My tv says itll need m4

It come with M4x6, M4x12, and M4x30. You can take a look at the user manual on the product detail page, under Product information-Technical Specification. All included hardware kits are living on it.
