I am a geologist who uses these drill bits to extract extremely small (about 100 microgram) powdered samples of carbonate rock for chemical analysis. Very cool to see this process!

[@seinfan9]

Do these break often and wear out quickly?

[@henrypeterson8497]

@@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

[@prumchhangsreng979]

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

[@henrypeterson8497]

@@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.

[@henrypeterson8497]

@@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

[@ParadigmUnkn0wn]

Several corrections: 0:50 - The grinding wheel is not "applied to a chamfered edge" it is creating the chamfered edge 1:23 - The centerless does not "grind them down to a specified length" it grinds them down to a specified diameter 3:18 - If that technician takes 4 to 5 hours to setup a single drill bit in that grinding jig... I don't know what to say. They most likely meant 4 to 5 minutes which is about right, or possibly the entire drill bit lifecycle from blank to finished takes 4 to 5 hours; however, I believe the former to be most likely. 4:09 - If it's impossible to see the difference before and after fluting, you need an eye exam. @Science Channel, if y'all are hiring for a script writer/editor, hit me up, 'cause y'all clearly need a better one.

There is a lot of mistakes in the video, probably bad translation. Once the lector talks "length", when actually he talks about diameter. Those hours of centering are probably also a big mistake, since the drill bit like this costs a few EUR from a good brand, and less than EUR from China.

Can't always use an edm.

4-5 hours to center the piece?! Definitely gonna need a chair

[@tungstenman2822]

as a manufacturer of tungsten carbide materials, I have to say the tungsten carbdie rod is very important for micro drill bits.

How is it possible that I can buy a whole set of these on Amazon for 10 bucks?

[@hyperhektor7733]

ebay 2-5 bucks

[@fristrm]

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.

4 hours to center a bit for a 10 second cutting operation?

[@rfengr00]

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

[@Runkpapper]

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

[@ogi22]

@@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.

100% carbide?

Yifan Gao Yes.

[@frigzy3748]

I guess he meant tungsten carbide

[@eng.renatocarvalho]

I doesn’t become fragile, it is the same material as before. The sectional area is too small, so any force applied there will lead to a big stress. So it is easier to achieve the yielding point.

I Used these drilled in the 1960s we had to buy them from Russia we were unable to manufacture them ourselves they were called spinks drill for thousands of an inch across You had to use a microscope

[@demandred1957]

So many nomenclature errors..As a Machinist with over twenty years experience, I can tell you a centerless grinder grinds the WIDTH of a part, not length. The blank was loaded into a collet chuck, not a clamp. And he was checking the flutes with a Optical Comparator, and a portable microscope. Not to mention most Machinist's could see the difference between the fluted and non fluted pieces with the naked eye (unless they are really old)..Any thing else I missed fellow Machinist's?

[@US_Joe]

I appreciate your comments and experience! 20 years puts you in an era with many modern techniques and technology. Proud to say my uncle was selected to be a member of machinists on the Manhattan project (he didn't know it at the time). God only knows how they machined these intricate parts in the old school!

[@demandred1957]

@@US_Joe Very cool! They machined them almost the same way we do today, with a lot more skill though, lol. They had optical flats back in the forties like we do now, and you can check flatness down to Millions of a inch with no problem. Johansen Gage blocks were a thing back then too (although very expensive and fairly new) and their so true to size and flat that you can wring two blocks together end to end and they will stick together without magnetism oil or adhesive. some say the gap between blocks is so small air molecues don't fit and it creates a vacuum. The main difference is the amount of time it took them to machine the parts on the manual machines vs CNC machines we have now.

[@Awegner176]

Just a lot of stupid things. They said chuck or collar and I think they meant collet. They also said it holds the carbide perfectly still but the spindle is clearly running. Good call on the O/C not being a "microscope". And the comment at the end about carbide being strong made my skin crawl. Nothing compares to the feeling of dropping a solid carbide boring bar.... Speaking on behalf of a friend of course
