Not sure if this will help but I found that a set of torch cleaning drill bits work really well for drilling small holes and they are super cheap. Picked my set up at the local hardware store for less that 6 bucks.

What are torch cleaning drill bits and how are they different from regular drill bits, which are available in dozens of sizes?

I guess what I'm asking is... there are already normal drill bits available in almost every size imaginable, so why would "torch cleaning bits" be any better?

The normally available (in the hobby anyway) "numbered drills" come in US wire sizes, which are expressed in decimals (thousandths) of an inch. For really small metric drills, it might well be better to have a set of those tip-cleaning drill bits.

Torch cleaners are really files, not drills.

I bought my first pin vise (holds small drill bits) and found a small set of bits made by "Dremel" at the same time, Years later i found the torch drill set also, bought 2 sets because they break so easy. They have been so much fun..

I had forgotten about tourch cleaning bits. It has been years since I've had them. Harry, they are tapered and you use them for cleaning the tips of acetylene torches. They get a carbon buildup and you have to lightly ream them. They could be useful in model building.

Torch tip cleaners are different from torch tip drills. The drills are actually steel twist-drills in sizes from about .022" to .065". They are used with a pin-vise, and are marketed in sets appropriate to cleaning oxy-acetylene welding and cutting tips.

Torch tip cleaners are very small round files in the same diameters, with a straight pilot-shank to start them in the torch-tip hole, and they typically come in a fold-up gang holder/handle to keep them protected but handy. I have several sets, and they are sometimes useful for modeling to enlarge a small hole without drilling.

A good set of Huot (still American made, I believe) micro-drills from .0135" to.039 (80-61 number drills) lives on my model bench. Real, decent drills, require a pin-vise, and available here, cheap:

The Chinee no-name ones tend to snap or go dull the first time you use them. What a deal.

The drill bits look good. I have the same Pin vise and I dont think it comes with the small enough holder for the bits. The Zona brand #37-120 could work better for you.

it says it will work with 0in. to 3/32in, does #80 and smaller bits fit in to those inches?

Every pin vise I've ever had, and the ones I use today, have one collet (chuck if you will) that will close down to "infinity" (completely closed), which will work with any of the smallest drill bits you will ever use.

While the drill sets sold by Xacto, Micro-Mark etc. are great, particularly for their drill index storage cases, individual drill bits from them are expensive. A few years back, when doing some pretty serious model car machining (yeah, I have a lathe and vertical mill here), I went looking online, and settled on http://www.discount-tools.com/CATALOG.htm which is an online tool jobber, who will sell to us ordinary mortals, as well as to industry. They sell those same numbered twist drills that come in the hobby oriented drill sets, in packs of a dozen of any one size, for very reasonable prices (around $3 per dozen). They sell online, and their delivery is prompt (small packages such as those are shipped via USPS).

Given that those very small high-speed steel (HSS) drill bits are fragile (they break very easily), this makes it very easy to keep a stock of your favorite sizes handy. (very satisfied Discount Tools Company customer here!).

Drillspot.com also has bits from #81 - 90 something. they are made with a bigger body so you can either finger twist or chuck them. the sets have multiples of the same size; they're prone to breakage via radial thrust.

i know someone will correct my explanation; that's the fun of posting!

Harbor Freight has a set of micro bits for around $8. They cut very well but are very brittle and break easily. I think any bits as tiny as the smallest in this set will break easy too. Consumables.

DON'T BUY CHEAP TOOLS. Walters makes a pretty decent set and there's a place that I think is called Drillmaster.com or Drillbits.com. They have the tiny bits with larger shanks and are supposed to be excellent.

Do yourself a favor and take a look at Dremel's cordless drill. I use it all the time for starter holes. Get an extra battery and charger for it.
