Got the first highly recommended by Jack Burgess in his video.  The second was when searching for really small dies.  Both are US companies if that makes any difference.https://drillcity.stores.yahoo.net/https://minitaps.com/drill-bits-wire-metric/

I get good tools from http://www.ottofrei.com - they specialize in jewelery making stuff. Prices are mostly reasonable, and I have found that most of the "unreasonable" ones are due to the products being significantly different than average (jeweler's saws being most obvious example). There are certainly other places, but they seem to have everything in stock all the time. Notably cheaper than MicroMark, for example, when they carry the same thing. Or sometimes at similar prices but better quality tools.

If you’re looking for a readily available metal with a high strength-to-weight ratio and good machinability, aluminum could be the right choice for your project. In addition, you should opt for aluminum if your part or component will be exposed to moist environments since aluminum alloys are generally resistant to corrosion.

CNC milling is a CNC process that involves the use of rotating cutters to remove portions of a block of material (or workpiece) till the desired custom shape (or feature) is made. It allows manufacturers to create intricate parts accurately while meeting tight...

This article presents seven aluminum grades commonly available in the market today, including their properties, advantages, and suitability for different design requirements. It will serve as a guide to help you make the right choice for your project.

I can not find my machinist guide at the moment, but as I remember for small bits 1750 rpm is much higher than recommended for these materials even when using 118°, "slow-spiral" bits. At the moment I do not have any #70 bits, but I have no problem drilling brass castings with standard 118°, #60 carbide or "slow-spiral" bits when running in the 400 to 900 rpm range. Slow going but very precise.

Although I use several suppliers, because they represent several good manufacturers like W. L. Fuller, I usually buy standard drill bits from McMaster-Carr. They stock bits specifically designed for softer materials like aluminum, brass and bronze.

Without a doubt, accuracy and precision are essential criteria when choosing any machining technology. But what sets CNC machines apart from other machining technologies is their compatibility with a broad range of engineering materials, including aluminum.

I should probably mention that DBCity has micro brill bits down to #79 and in metric down to .05mm (.0020").  Smaller can be had but ya have to call them.  And pay thru the nosehttps://drillcity.stores.yahoo.net/newmidrbi.html

Also, I have bought drill bits used for drilling PCB circuit boards and in CNC machines. They have a larger shank than a standard drill (helps reduce breakage) they are usually 0.3mm to 1.2mm (that's about a #81 bit to #56)

Like with many other engineering materials, aluminum has its drawbacks. Here are the disadvantages of aluminum for CNC machining:

As you may have realized, aluminum offers several desirable properties and is easily machinable using CNC machines. But is aluminum the right choice for your product design project?

Companies around the world use CNC machining to craft high-quality components from diverse materials like ceramics, wood, and composites. Metal and plastic take the forefront in mass production, with metals enjoying wider machinability. Machinists can adeptly tackle...

Yes quiet expensive, but durable, to not say indestructible in modeling use; the milling cutter have more than 30 years of heavy use and they work better than any Dremel new one or similar modeler offering.

But just because CNC machines simplify aluminum machining, it doesn’t mean fabricating aluminum parts is any less complex than it used to be. There are many aluminum grades (or alloys) available in the market today, and the success of your project will depend on you choosing the most suitable aluminum alloy for your project.

A #70 bit is quite large by microbit standards at .028" so it should be fairly robust.  I use a powered screwdriver with a micro chuck attachment to drill holes.  Not sure of the RPM of the tool bit it will drill through brass quite well!  Light steady pressure and let the bit do the job.  The last set of bits I purchased were labeled for "welding tip cleaning". Twelve bits starting at #76 through #55 I think.  Sharp and rugged.

I tried the inexpensive high speed steel bits in a drill press, #70 bit at 1750 rpm drilling through a cast brass headlight to run wires.  It simply annoys the brass and does not produce chips.

Small drills can be spun much faster than 1750 rpm, their small diameter means they need very high rpms to get their surface speed up. I'll check my micro drill press tomorrow and see if I can tell what it's rpm range  is....DaveB

I don't really want carbide bits.  They are sharp and can last, but they are extremely brittle - they will not tolerate any bending, you must use a good drill press with little runout (wobble) and clamp the item.

But even after you take the plunge with aluminum for your project, you still need a high level of CNC machining expertise to create your parts accurately and precisely.

The products I have received from Widget Supply  https://widgetsupply.com/  have been good quality.  I have not purchased bits from them but they list High Speed Steel HSS bits in the small sizes.  They also have lots of other tools and materials of use to modelers at reasonable prices.

The bits are first rate even the smallest one cut like a new; course they break like the other if you work not properly with them, the same with the taps.

I do the same with brushes, and all the hardware necessary for modeling use;it comes from the professionnal hardware, I never have regret to make the investment
