How to drill?

[Keeferes]

I see alot of people talking about drilling out air holes on multiple devices. What I don't see is anyone saying how they do it. They give the sizes they drill too though. I would assume most use a small machine vice and a drill press, but was curious how many folks use another method?

I used a corded drill. I hold the device with a plastic spring loaded clamp, kinda like one you would use to hold two pieces of wood together. The jaws are soft, but not too soft, so there is no damage to what it's holding.

I purchased some metric drill bits through Ebay. What I use is a cordless drill. I drill it by hand.

What material drill bits do you recommend?

The chuck on my cordless drill won't close small enough to hold a tiny drill bit. With the chuck closed all the way, the bit slides in and out of the chuck, so I use my Dremel (with a small collet) and hold the cap in my hand. Probably not the safest method.

I would spend the extra money and buy a cobalt drill bit made for high tensile steel. I believe I spent less than $2 for a 1/16 bit at our local Lowes. Made quick work of enlarging an airhole and drilling out the center pin of an RDA for bottom feed conversion. A cheapie drill bit made out of Titanium or one of the other materials wouldn't have done the job or would have snapped when applying the pressure.

What Hdiver said! I ruined a top cap using a regular drill bit. I ended up getting cobalt bits. Cordless drill, black and decker. The battery pack is really heavy, so it sits nice on a surface. Wrap the top cap in a dish towel. Hold the cap, wrapped in the towel, with regular pliers, with airhole up to the drill bit. Start off slow. The cobalt will drill thru stainless rather effortlessly, so high speed is not necessary. I just pulse, and get the airholes drilled out to how i like.

My question is if you are just enlarging a hole that is already there that is pretty easy to do by hand... But if you are adding another hole, I wouldnt want to do it without using a drill press. Anybody do this without a press?

What I was trying to describe in my first post was this clamp, I used it to drill new holes, open up my Protank2 bases, and RBA post.

I've always held the atty or cap I'm drilling in my hand. I use a corded variable speed drill and cobalt bits for 1/16 or larger. I've got a small cheap metric set I got off amazon for smaller.

I take it slow and go up in steps which it helps keep heat and the possibility of broken bits down. If I feel the material heating up I stop, let it cool off then start again.

Let me get this straight ... So, your drilling out this hole (red arrow) on your Kayfun Lite Plus just a little bit in order to get an easier draw?

Quite often yes, many of the clones come with air holes that are drilled smaller than the authentic version. The first releases from Tobeco were very bad I've read but it seems to be getting better now. Still many are smaller and some people...including me drilled out.

Has anyone here drilled out their kayfun clone? Curious about size and results - would be nice to get rid of that whistle.

The newest Tobeco KFL+ clones have a much larger airhole not leaving enough meat in the base to drill any larger in my opinion. With the airflow screw on its largest setting or completely removed and the restrictive stock drip tip replaced or cut down, I find the draw to be great and I only do direct lung inhales.
