Drilling a Hole the Width of a Human Hair?
Рет қаралды 175,048
26 күн бұрынIn Adam's previous attempts at drilling the smallest bits he could find, he achieved holes the size of three sheets of paper. But with the latest revelations and upgrades he's made to his Dumore drill setup, he takes a stab at drilling a hole with a diameter of .1mm--the thickness one sheet of copy paper or roughly that of a human hair!

Lubricate your bits, use beeswax or anything but good lord use lubrication. Those tiny bits heat up fast. You'll cut faster and the bits will last much longer. Just push the wax up as the bit is spinning at the slowest speed. That is a jeweler's dream setup!

As a former 'professional fuck around' I can tell you that when you have the capability, you find the need. I used to do industrial maintenance and repair, and when everything was up to date and nothing broken I was allowed to fuck around finding new ways to improve our machines or w/e I felt was worth my time. I guess technical verbiage would be R&D, but I prefer 'professional fuck around'. But yeah...when you work in that kind of environment and get a new tool or capability, you find reasons to use that new tool/capability that are bullshit at first, but you quickly melt it into your arsenal and pretty soon you're primed to whip it out when it's the best tool/technique for something you've been doing a harder way all along or a new problem comes along that it can solve perfectly.

I worked in a very small machine shop and we got a job to drill .030 holes in stainless steel tubing . Only got 3 holes out of one bit . At the time I was using MotorKote oil additive in my cars motor , it is a liquid polyester that would give me 10 % better gas milage so went home got a bottle and back to drilling , when from 3 holes to 28 holes , way better bit life span .

Some stainless is an absolute nightmare to machine. All of it's pretty bad but some is extra bad. Some stainless work hardens. So as you're drilling it if you don't feed it'll get really hard. With a small diameter drill you can't exactly lean on the quill. But what you do when it case hardens is you slam the bit down into the bore. Just what works.

That is outstanding, Adam. In a way, takes me back to my working days. For 30 years I worked with wires that had a profile of 0.014" or 0.35mm and had to thread them into a catheter with a channel of the same diameter. That was a real challenge. For those wondering, those are the diameters of wires inserted into coronary arteries to unblock them. On occasion, we'd insert a 0.009" or 0.23mm diameter wire. They could be tough to see.

Once we needed holes that were 1.2 thousandths of an inch in diameter, drilled through a piece of stainless steel that was about 5 thou thick and about 3/16" in diameter.. The method was to predrill most of the way through with a larger bit, then switch to the final size to poke the hole the rest of the way through, The application was to squirt a beam of electrons at 20,750 volts (DC) through that hole.. I mention this to point out that, usually, when you need holes that are pretty small,, that they often don't have to be very deep.

That’s a 100 micron drill. When I was in the blood analyzer business we had specified Ruby apertures at 50+/-1 micron diameter 40 micron thick (cupped profile) for impedance counting of diluted blood cells (Red, white, & platelets). When we visited the Swiss Jewel manufacturers, they described the process: strung together on an ~1 kilometer long tapered wire spooled at either end. As the machines spun the stacked discs it dabbed diamond dust abrasive on the wire. As the wire moved in and out, it would eventually reach the 50 micron end, upon completion. We developed an optical inspection system on a microscope with a “drawing tube” that we could superimpose our AutoCad- generated template scaled to the 50+/-1 micron image seen in the microscope.

some years I briefly work in A electronic Assembly lab. I was in charge of repair and maintaining several different machines. one of the machines was called the Lead attach machine . The machine had a wedge that had a hole thru the middle from top to bottom which gold wire was fed to make leads to attach the die to the ceramic case. You had to look through a stero microsope scope to see the wedge. There was a tiny hole on the back side of the wedge where the wire was fed tru. You could not see this hole and you just had to play with it until it came out. The day I mastered this was they day the company I worked for decided they did not need my services anymore!

There is an old story about two competing Jewelers...who could drill the smallest hole? Year after year, each craftsman managed to make smaller and smaller holes. The last year of the Contest, one of the Jewelers was puzzled...rather than a test-piece with holes drilled in it, he received one tiny drill-bit....and it was smaller than any he'd ever seen before! He called his friend to see what was going on. "Look at the drill-bit!" was the terse reply. Sure enough, the Jeweler had not only made the the finest drill-bit ever seen, he had drilled a hole through it! "If you want to see the smaller drill, you'll have to visit!"

amazing, smallest I have drilled was 0.5mm but that was via a flexi shaft from a dremel, and I was drilling stainless steel sheet hand held, I sometimes didnt manage 1 hole and other times I would get 20 before I broke the bit- I used carbide pcb drills (look very much the same as the ones you were using, but I bought about 5 packs at a time.). I do have an optical measure (a microscope with a calibrated platen, commonly used to measure tiny thread pitches by counting 10 teeth and then measuring the offset from the start.) I guess one of those could be pressed into service to measure hole spacing while drilling.(I do have 3)

Metric system was developed by the FRENCH, a republic if I am not mistaken.

@JointerMark never let facts get in the way of a bad joke. Otherwise, they would know the only reason the USA didn't convert to metric is because the ship with the shipment of metric standard gauges sank in transit.

It's funny how I watched during lockdown, then kinda fell away (I love Adam, less interested in other people, I get that I'm weird, it's no slight upon them). Anyway, I remember him making the clapper board, and to see that they've decided to never remove the tape from the previous show makes me happy. I'd love to find the episode in which that was decided, or the lore behind it is explained, but it makes me smile every time. KUTGW.

I'd be spending an entire day trying to think of reasons I need tiny holes. I'd invent problems just so I could use that magnificent drill press.

My dad used to do this, drilling holes tinier than a human hair with electric discharge machining. I miss my dad sometimes.

I must have missed the previous vid, as I was guessing EDM or ultrasonic until Adam showed that catalog. Wha?! Actual drill bits?! 👀

A couple of nice add-ons I can think of would be a compressed air chip removal system (maybe paired with vacuum), and an eye shield (like a section of a motocycle shield) mounted near the eyepieces
