Amateur move, I know. I broke a dang drill bit off in my AGA-T2 air hole trying to drill it out. Does anyone know if I can buy just the cap piece, or do I need to drop the coin for a whole new unit? I dont really have the snaps for that at the moment. Im going to see if the guys at work can drill it out on their press (I was using a hand drill....) before I pursue other options. Be careful people!
Crap....broke off a drill bit in my AGA-T2 air hole

can you grab either end of drill bit with needle nose pliers and try tuning it out?
Grab the other end with needle nose pliers and gently twist it counter-clockwise...it will come loose and you'll be fine! 
Remember to lightly sand the edge on the inside to get rid of any burs that will be there.

I dont think I can, although I will give it a try. It was just the tip of the bit, and it is fairly flush in the hole. I tried using a hammer and punch to get it out to no avail. There might be a little nub to grab onto, but not much!
The guys in our machine shop fixed it in a jiffy. However they only had 1mm and 1.5mm bits. I went with the 1.5mm hole, and it is wayyyyy too airy.
Time to shrink it back to my original desired size of 1.18mm (#56). I'm going to either plug the hole with epoxy and drill it out, or glue a piece of aluminum can flush to the inside and drill that. Anyone had to do this? Any preference?

Foil tape (not duct tape) applied to the inside wall is an alternative as well, then just punch the size hole you desire. I'm not crazy about the idea of adhesives that close to heat from the coil and inside the vapor chamber, though.
Find a 1.5mm diameter syringe needle and jam it in there then file it down to match the top cap profile.
I'm surprised people want the hole bigger. The air hole is a bit too big on this atty for my taste! I like to feel just a little more resistance in the draw...
There are two revisions of the AGA-T+/2, although most sites don't designate which they're selling. The earlier models had the smaller airhole.
Same here. My original hole was far better. Drilled mine out to 1/16 as others have suggested, and it is WAY too airy/loose. Mine was much better before, but then again I didn't have the other type with the super tight draw. I imagine those with the super small hole probably did notice a big difference when drilling out to 1/16, but actually those with the larger original hole were already at the perfect size.
I'm beginning to realize you kind of have to take what others say with a grain of salt when it comes to mods. I've found a lot of the stuff people claim makes a "huge difference" actually makes an already properly working setup worse. Unfortunately the upgrade bug has bit me several times, and when someone claims I can get even more performance, I'm down to try it. When it comes to the AGA-T+, I think I'm just going to get another one and start over as this isn't the only mod I've done...u-wick, dual coil, dual wick, cotton wick, all were a bust compared to a properly setup single wick 0.9 ohm 28 gauge coil. Which I can still achieve, but now I have a second air hole for a second coil that I've got covered with a piece of aluminum can, and a wick hole I'm not using that's plugged with a piece of stainless steel mesh. Add the airy draw into the mix with the original hole drilled out, and it just gets frustrating having turned a fairly nice device into a "frankenstein monster" when something doesn't work out.

After vaping all afternoon and evening with the 1.5mm hole, I am beginning to like it. Initially, it just seemed like a bad thing because it was different than the smaller hole. The vape is a bit cooler, which doesn't bother me, and the juice tastes more flavorful. I think the extra airflow over the wick/coil is cooling the coil better (32awg kanthal with a 5/6 wrap), and the juice isn't getting as hot. Vapor production has also improved. I had to alter my draw a bit to match the additional airflow though. I may end up leaving this as is....
