I personally dont find the diamond bits working well for me for drilling vs a good cobalt bit. I do use the diamonds to smooth out the burs left in the inside though.
Drilling out air hold advice

Was in machine shop in high school and trade school and the smaller the drill bit, the faster the bit should spin. Slow speed with small bits can cause the bit to break off inside the piece. Always use lubricating oil.
If using a small drill bit at slow speeds, the drill bit has a tendency to act like a screw and burry itself into the metal, which snaps the bit. When the bit is moving at a fast speed it will do its job at cutting the metal.
How many times have you drilled through a thin piece of sheet metal with a small drill bit only to have the drill bit not cut the perfect circle, but "screwed" itself down the entire length of the drill bit and had to be reversed to remove the drill bit. Same principal applies to small bits drilling through solid metals.
Drill bit speed also varied depending on the metal being cut and drill bit type used.

Good info, but high speed drilling will also generate heat which will weaken and dull the bit and probably end up causing it to snap anyway.
Yeah I would not drill a new hole with it. But to open and existing one in stages its very easy to do with less risk of walking for those not used to drilling. If I was going straight to 5/64 I'd use a bit and drill.

The process is not a big deal for someone used to drills, But if they have never really used a drill and especially if hand held, they are very likely to walk to it. I also was specifically talking about opening a hole not drilling a new hole, for new holes, punch and punch a few more times. Start with a small bit and then go bigger .
Rubber bands on some vice grips
new drill bit
The cyclone is easy to drill
the tape and book are prolly good tips to assist you
good luck!

If someone does not have much experience with drilling through metal, they need to know to keep the pressure on the drill to a minimum just as its breaking through, that's the point where bad things can happen as the drill busts through. Bad things meaning, the atty might get caught on the drill bit and start spinning, hurting your fingers or similar. You can usually tell when you're nearly at that point, you might notice a slight reduction in rpm of the drill as the bit starts to see light at the end of the tunnel and it seems to dig in deeper than before. If you notice the rpm slowing down just back right off the pressure as the bit exits the other side.
This diamond bit in a Dremel works great on SS. The advantage is it fits in the small hole and reduces the risk of a regular bit jumping or walking, Plus you can go up in size slowly to any size not just drill bit sizes.
Nothing from Dremel looks like the bit in your picture

I did it!!! Piece of cake. Two local hardware stores and all I could come up with was 1/16 cobalt drill bit. A drop of VG, slow steady pressure. Viola! Perfect. Thank you for the guidance.
Not sure if it's been said yet, but I just got done drilling my igo L. first hole I "enlarged" and now I got juice leaks, tried drilling a second after I got a smaller bit, 2 bits actually, and they bot broke befor I could get through, resulting in and injury 
if you buy some some quality bits, go for more small holes.... but this is off speculation

MN, what difference have you noticed with the larger air hole?
Okay not to quadruple post at the end here, but.... When you guys punch or score, aren't you worried about bending the atty? I thought about doing it, but I didn't because of that concern, didn't try the tape either, just went for it, but of course the bit broke, next bit walked a bit, and now the holes aren't perfect, but airflows alright
The 1/16 is just a tad too airy for me but I use a single coil and don't sub. I think it would be better at lower ohms or direct lung hits. No leaking tho. But it was easy to do (thinking it was the cobalt bit) and I'm otherwise happy with the clean results. If I can't tune it in I may offer it up as a trade.
I use a spring loaded punch, so I'm not wailing on it with a hammer. http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=spring%20loaded%20center%20punch
I should add…the stock air hole was waaaaay too tight. I can't imagine anyone using the Cyclone without enlarging the hole.
