How Micro Drill Bits Are Made | How It's Made 

🤣

Oof

Collin Regalia What you help create are incredibly amazing!

hearing can take 4 or 5 hours I was like nope

Ya they cost so little it cant really be 4 to 5 hours

Up to 4 hours of centering 1 drill bit... Thats insane. I wonder how much one of these cost...

@@Chris-yy7qc the Mitsubishi micro tooling I use can cost up to £300, I think was the most expensive I've ordered so far atleast.

@@wildin13 i run 0.006 in drill all day long.

@@hvuu1628 I think we had (until I accidentally stabbed myself with and broke) a 0.1mm 15xD ball endmill for nearly 5 years. Granted it was used to machine detailed graphite electrodes

@@hvuu1628 the reall skill is not using them but setting them, am I right..?

Do these break often and wear out quickly?

@@seinfan9 I've never had one break, but the relatively soft minerals and small sample size means I don't put a ton of wear and tear on the component. I also do mostly spot drilling--just straight in and out with the bit. When I occasionally do rasters or transects where the bit is moving horizontally I get more nervous, but no issues so far

Slightly off topic but what are u doing that for? To anaylize the age of certain object?

@@prumchhangsreng979 I'm interested in the stable carbon isotopes present in the rock. It's from a period nearly 600 million years ago called the "shuram excursion" where there is a really mysterious isotope record in carbonate rocks from all around the World. We're trying to figure out what caused this signal; could be related to changes in ocean circulation, photosynthesis, or many other things which affect carbon isotopes.

@@youtubeisgarbage900 I'm not sure exactly what you mean, but I'll do my best. First, my research is not carbon dating. Carbon dating is the study of radioactive 14C, which is produced in the upper atmosphere by reactions with cosmic rays at a fairly consistent rate, and decays into nitrogen at a very consistent rate. By comparing the 14C content in a sample with the original content (which we infer) we can estimate the time elapsed since something stopped incorporating carbon from the atmosphere (for example, when an organism dies). Since 14C decays rather quickly (around half of any sample will have disappeared after just 5000 years) we can't use this method to date things more than a few hundred thousand years ago. Instead, my research is focused on analyzing the two stable isotopes of carbon, 12 and 13, by which I mean they do not decay over time. So to your comment, most charcoal comes from the aptly named carboniferous period, which was indeed more than 3 hundred MILLION years ago-no chance at all of using 14C carbon dating. I'm not sure what iron tools you're referring to (again, I don't do carbon dating) but I can tell you they are not millions of years old, both from a human evolution and carbon isotope perspective. Hope this helps convince you I'm not a fraud

That is pretty much it.

@@manzoorathar11 This is not programming. It's the same false concept as like "The king build a new castle." No he just gave the order to do so by his peasants.

Virgin auto vs chad handle

@@wernerhiemer406 Thats how I explain Barak did kill Bin Laden. Only a fool thinks you mean Barak was on Seal Team 6 running inside a Pakistan home with an H&K MP7. You get the fame and the blame when your on top.

Okay yeah, when you use a plc normally, you just have to press a button to break a pause state. But when you start manufacturing the other products or when there's a quality control issue, that same person could be trained to modify the program.

Also, @2:26 the chuck doesnt hold the blank perfectly still, its holding it centered - you can see the end of the blank rotating as the two wheels "close in". Glad Im not the only one bothered by the small errors

The video was the food, this comment was my dessert 😋🤣

Those are pretty big errors in voice editing. Nice. Catches

Takes him 4-5 hours to set up because he's union.

They also called it a "collar" instead of "collet".

Yes they should probably have added the phrase "without using magnification" (the image on screen was clearly magnified).

@@pete3897 clearly wasn't. At most I'd say it's a close-up.

I think taking a close-up picture of something with a CCD then displaying it on a bigger-than-life monitor classifies as magnification. Try looking at a similar drill bit in person at the same distance as you viewed it on your screen. I think you'll find the fluting hard to discern.

@@pete3897 I actually have some, and a dumore drill that uses them. You can see it.

he means its impossible to see with your eyes

hey you wanna know a wooden maus tank is built? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-l8vTc0Sxv20.html

Same haha

Johnny Wayne thank you!! I was hoping someone else caught that.

Being a machinist I caught that immediately. Happy to see I wasn't the only one!

Also, "Places it in a waiting chuck or collar". Could that be a collet? 2:15

@@icabod3374 Yep that would be a collet, lol. Saw that one too, as well as him saying "... The diamond grinding wheel is applied to a chamfered edge on one end of the blank..." Instead of saying that it's cutting (or applyING not appliED) the chamfer on one end. Also a bit humorous that he says, "... associated with carpentry..." tho most anything will cut through 99% of all woods. No real need for micro carbide drills most carpentry, probably moreso associated with metal work, fabrication, {metal} machining, etc. I'm also a machinist, a journeyman, for just at 25 years now.

@@johnnywayne7654 yeah and then we have the ppl for whom this vid was made which are well ... lets say less likely to be versed in machinist lingo or have a clue for what any drill that is not bought at the home build store might be used for. Still it is amusing if you know.

What do you use these really small bits for?

@@Aditya-wg3lp really small holes or really small features. U can’t make a tiny detailed part with a 1/2 endmill

same

@@Aditya-wg3lp I've got several of the hair-width end mills (errr...router bits) - I use them for inlaying. The most common use is for improving corners - draw a 90 degree channel with a 1/8" bit, and then run a 1/16" along the edges followed by the sub-mm one. I've also got one made specifically for ivory (I've got some mammoth ivory bits). You have to be very careful with speed and depth on these because they break super easily if the parameters are wrong, and they're not cheap to replace.

​@@Aditya-wg3lp I'm an aerospace and medical supply machinist. At my workplace, we mainly use these tiny little guys to produce very complex, high pressure valves and to machine cross lines between two high flow sections to facilitate very precise mixing of liquids. Sometimes the tiny holes that are drilled are also used to control the opening and closing of mechanical solenoids

He tried

That man's name? Albert Einstein

@@laurencebrown1781 Einstein died in 1955. NASA wasn't created until 1958.

Christopher U.S. Smith It’s truly incredible just how much you missed the joke

@@grantcambron3597 What joke? There's no vocal inflection or LOL or emoji to indicate it was a joke.

They need sharpshooters😂😂

It needs to be so precise I don’t know if there would be a better process

That's why they should be hiring Mexicans. They will do it faster and better Everytime.

It's not per drillbit, it's for setting up the machine the first time, after that you can cut thousands with no extra adjustment.

@@aleksandersuur9475 yeah 5 hours is a short set up actually, I've spent a week on set up before

Lengths of 100% carbide called blanks.

Not 100% carbide, they usually contain about 10% cobalt

Hmm, Yes, The floor here is made of floor

@@vejymonsta3006 I had to listen to it a couple of times before I heard 'lengths'.

Gerit Flesner And with this joke, you’re finally able to graduate father school

@@blitzwithspartan6175 Yup! 😂😂😂😂😂😂😂😂

Hahahahha

That hurt to read.... Thank you

Legendary...

NBD. The script is misleading. It takes hours to set up the shims, then you can make a bunch of bits. The finished drill bit only costs a few cents.

Yeah, there was a real lack of proofreading on this episode.

when if you press something for reduce the diameter , the length increase (atleast for metal it work)

i noticed that too haha

@@dr.shadox4927 It was a centreless grinder. Two diamond compound coated drums grind the diameter down to size, not the length

@@letsgoBrandon204 oh ok it was a grinder , nevermind in this case. though it was like a roller pressing it.

I would say "diameter", amigo... :)

@@amigator7789 yea, I tend to think orthographically. But, touché anyway.

You tried to one up the announcer, then got one upped in the process.

The blanks do call for a specific profile length.. Including the diameter and the back angle

Good luck

How much does one of these drill bits cost?!

@@Chris-yy7qc last one I saw was around 400 dollars.

@@Chris-yy7qc Smaller ones or extended reach ones are more expensive. www.mcmaster.com/2841a91

I hope he was aligning a fixture that may hold one drill bit at a time, but will process many thousands before needing work.

I once accidentally stabbed myself in the palm with a 1.55mm bit. It made a pool of blood the size of a dollar coin in my hand. Its been two years and theres still a light spot on my hand from where I stabbed myself.

@@crazitaco blood blisters are satisfying to pop tho as long as you don't leave them so long they hurt like a bitch

The shitty China ones are automated and have bad QC most of the labor in the process have to do with quality control not actually making it

With additional CNC equipment it can be automated more. With a single machine you can grind the OD down to size and flute on the same machine

It usually is. I have no idea why the wouldn't have 3 cnc machines.

chinese drill bits are fairly inexpensive but fairly decent in performance.

Shhhhhhh it is one guy just trying to justify his job. He is so close to retirement! Tis a secret! 🤫

Every manufacturer has its own requirements and threshold for quality. In this video, it is clear that they were making industrial grade, precision drill bits.

I have a feeling that its per batch, rather than just 1 individual, but yeah, it seems excessive. Maybe its 4-5 minutes.

Yeah, that's what I was thinkin. He must be shit at his job if it takes him that bloody long lol

@Colorado Strong Thank you so much we always are in need of spelling help, and it is welcomed, Lance & Patrick.

Tehran Kizaki but you just don’t get it do ya? He said it was impossible.

A good ER or SK collet can get you under .0002 runout.

Found this on the subject. Zero runout is easier than you thought, heh. pages.mtu.edu/~microweb/chap6/ch6-0.htm

@@sleeptyper oh?

Yeah no shit huh? A makita breaks my 1/16” drill bits with ease

@@louisedwards6681 It is based on belt driven chuck, with the belt tension nulling all slack since the chuck is pulled against diamond bearings.

I happen to see a drawing of a 10 mm thick disc which required four holes of Dia. 0.5 mm at 45 degree angle ... These holes were required to control the flow of fuel i.e. liquid hydrogen and oxygen (in liquid propellant engines i.e. aerospace industry) ... Such small holes allow for expansion of liquid to gas as well ...

@@muhammadharisnisar is there no better way to make these holes than to use a drill bit

The bits have to be at least three times bigger

Betul buat para semut bikin sumur bor

@@muhammadharisnisar that's still almost twenty thousandth. That's huge compared to the bit in the video. We have a catalog at work that list drills down to one thousandth dia. You could break that by looking at it wrong !

If your drill press can hold it perfectly straight, you're fine. It's very strong when compressed. But it can't be bent at all.

For what purposes its used ?

Drilling holes in circuit boards for connections. Although the bits I use must not be made like this cause they're pretty cheap, like $5 a piece or so

Advice on speeds and feeds sir?

If Abom did it it would be 6’’ in diameter 😉 !

@@mrc1539 Also he would do atleast 2 scratch passes before even trying to do the real grinding...

Lengths not blanks

Yes. Precision cnc lathes can hold geometric tolerances in the microns. Fiber optic applications require tight tolerances for proper operation.

Its interesting! LOL 😄😃

Can't always use an edm. Maybe the part won't fit, or you're using it for surgery, or the part isn't metal, or it's in an environment or location that prohibits the use of an edm and it can't be moved, or you can't afford an EDM. There are lots of good reasons to use these. The only downside is the rigidity is critical. You need very little runout and a very stiff drill press.

Cant edm fiberglass

Chicken .!!

... and then the Swiss engineer sticks in the german engineer where the sun shines throu his hole.

And thus, the birth of through-spindle coolant.

Thats what I was waiting to see. I'm guessing the wasn't a way to get a good camera angle in the machine.

The videos on this RU-vid channel are just small pieces of larger shows on the Science cable tv channel. The bigger shows there are much better.

XD

ebay 2-5 bucks

You dont buy the same type of drills as this endmill is, the drills you buy can even drill allot of the materials this "Endmill" can.

@@fristrm i dont know what you want to say,

chinese 6 year olds make them. they work for just rice

@@fristrm "Allot" is to apportion something, generally money. "Alot" is a town in India. "A lot" is more than one. Wake up and teach yourself homonyms and homophones.

Good thing these videos were made for the general public.

Well, as all machinists or experts in any subject would know, it takes time and money to reach high precision and quality. It’s just the same in the film making business. This film is cheap and good enough for ignorants, like 99% of everything, sadly. How this transfers to politics is frightening. 99% of a population have no clue and no desire to study past the bullshit in politician’s arguments and yet vote for them. If only we had a micrometer to figure out the bullshit from the truth it ‘d be easier.

@@scslre I'm not a machinist, just a guy who likes to tinker around with tools, and the terminology in this video made me cringe too. Lets not make excuses for poor research on their part.

Could you tell me which carbide they used?

@@SanoCrushridge the blanks are tungsten carbide. This video doesnt show any coating of the drills, but it's quite common for these drills to have some coating on them, depending on performance requirements

@Sir Scofferoff and it‘s more accurate

What kind of tool holder do you use to hold those drills in, special collets? And how do you make sure you don't force them in to whatever is in your chuck too quickly to the point of them breaking? I imagine you must have some very fine motor control to keep them in tact and now screw up whatever you're working on?

Not Dave I can’t see that, as they’d be out of business. Those bits are not that expensive.

Just guessing it's for the first bit. After that you can use the same setup for the same size

@@Runkpapper not really... it seems he is centering every bit, but it for sure doesn't take 4 hours. Did some centering of tools and tool holders for rotary milling machines and those are WAY more compicated than this little thing.

A job is a job💪

@@Runkpapper I thank so to ,that makes sense 🤔

Yifan Gao Yes.

I guess he meant tungsten carbide
