Drilling through a lathe cutter is impressive. I've never thought about EDM for drilling. This is genius.
Hey Dustin!
EDM is used to drill the cooling channels in turbine blades and vanes used in jet engines.
Been doing this since 1981, not exactly a new technology. However, having it affordable for a home DIY'er or hobbyist IS exciting. I do mainly wire EDM.

SmarterEveryDay Dustin I found a video a little while ago that introduced me to EDM drilling. Try searching on KZhead for “Drilling through pencil lead”. That’s where I became fascinated :).
"Honey, where's my large mixing pot?" "You mean the large colander?" "No, I mean my big mixing bowl from the KitchenAid mixer" "Yes. You mean... the colander."

Hi Cody, if you are interested in an Arc generator, I have a good deal for you. See my contact details on my website baxedm.com
@@baxedm9806 man is there any chance for it to be cheaper than 3k? maybe some reduced in capabilities thing, or whatever ...

>It'll be too conductive >water your plants with it It's got what plants crave. (Electrolytes)
oh god i love that reference
Plants love heavy metal
Mostly iron copper and zinc the nano particulates are what make the water more conductive not salts.
@@Barskor1 salts can definetly make water conductive, just adding a bit of tabel salt to water does make it conduct electricity quite well.
@@turk639 Yes but that is not what is happening here he used distilled water that over time gained higher conductivity by drilling.
Not only is this impressive machining, he provides an articulate and thorough explanation of how it's accomplished. Accolades!
A lot of years ago, I used one of these machines to remove broken drills, taps and hardened steel pegs from materials. It was extremely good at doing this and due to costing, worked out cheaper than re-machining the whole part again - mainly because I worked cheap. For fun, I used to make strings of ball bearings, similar to pearls, from worn out bearings.
lol I read the last line wrong and was like... a ball-bearing thong doesn't sound comfortable XD
@@g60force Hmm, never thought about that but am thinking that a few odd nuts might make for interesting thing, for the very brave....
Makes me want one so I can drill random holes through random hard metal objects, just because I can!
Matthias Wandel stay away from the wife’s pots and pans
All the bad ass dudes got this vid rec. Dude, your vids are great. This vid is awesome too.
I cant even imagine what uses youd come up with for this thing lol
Tell the truth, Matthias - you're in a mad scramble to build this in WOOD, huh? AvE, OTOH, is just waiting to tear this bad boy apart!
Go For It!!! Whatever Drills your hole!!! Right?
when I was younger my kid used to tell me stories of homemade EDM machines that I always dismissed as urban legend. I've seen that baxedm stuff around, great to see it implemented. Looking forward to seeing your wire feeder / tensioner. I talk alot when I'm excited; moral of the story: Amazing work!!
Do you mean your dad/friend/etc rather than `kid'?
@@channel11121 /r/whoosh
i'm pretty sure you're ordering parts right now Tony. Can't wait to see your version :-)
Dude, your vids rock, and this vid is freakin' sweet too!
Here's an example of how a DIY wire feeder and tensioner for Wire-EDM could look like: kzhead.info/sun/qNdse8yMbqRmZJ8/bejne.html
My brain just melted. What a great introduction to EDM, was very informational, thank you!
I once had a conversation with an engineer - he talked about a project he was working on. It was about EDM machining; they used a wire about the thickness of a human hair. It was so precise that when you put two freshly separated pieces of metal back together and left them for a while, they'd fuse back into one piece. Since EDM is pretty slow, they'd devised a system which was able to re-inject a new piece of wire using a jet of water should the old one have broken when running unsupervised during the night or over a weekend. Fascinating stuff!
Did he mention the type of metal he was using?
Me: "Huh I wonder how (any advanced topic here) works?" Applied Science: "Here I've made this cutting edge technology in my garage, and made an great video about it."
Cutting edge. Ha... Ha... Ha...
Honestly, I'd love to get to know this guy, buy him a few drinks, hang out with him. If nothing else, I'm sure some of his smarts would transfer by osmosis to me!
@@Ariccio123 I second that
"Cutting edge" being 250 years old....ok.
@@vidznstuff1 Arc gouging technically may qualify as EDM, but I dare you to try making a 0.6mm hole with your welder.
When I was in Grade 8, a buddy and I built an EDM drill starting from an article that had been in Popular Mechanics. I got a section of a many-splined transmission shaft to use as a "tool" from a shop that fixed Kenworth oilfield trucks. That was pretty hard, high-grade steel, and it was able to drill a close-fitting hole through a piece of 1-1/2" mild steel or aluminum plate. The plate being drilled was submerged in Kerosene in a clear Pyrex dish, so that the arc discharge was actually covered by the liquid. Raising/lowering the head for the cutting tool was a vertical slide made of maple, both the track and the movable head that ran in it. The maple slider holding the "tool" was raised and lowered by fly line running through a multi-line block & tackle made with Meccano pulleys. We got a very slow-turning gear motor out of a junked Timex watch display, which very slowly un-reeled the line, lowering the cutting tool. The speed for lowering the cutting head was one of the hardest things to get right. The winding motor wasn't variable speed or reversible - a hand crank raised the cutting head. We cobbled up a circulating pump using an automotive-type mechanical fuel pump with the actuating lever arm moved by a maple cam on a bolt chucked in a 1/4" electric drill. We put a diode in one leg of the power wires to slow the drill down. We made a tapered glass tubing nozzle for the hose where it "squirted" at the workpiece. That flushed the cuttings away from the tool pretty well, although not as nicely as if we'd had a tool head with a hollow center to pump the Kerosene through. The cuttings built up quite quickly, and we discovered that things didn't work so well if the liquid was full of metal cuttings. The solution for that problem was to drain the kerosene full of cuttings into a reservoir. Some settled out, and the pump output ran through a Diesel engine fuel filter. Our high voltage supply was 120 VAC going through a voltage doubler or tripler power supply, using some big capacitors, some big incandescent light bulbs for current limiting, and some high-rating diodes we obtained by writing to a solid-state component manufacturer. They sent us a box with 2 or 3 sets as well as some heat sink material free of charge, which was good of them. All this back in 1969 - 50 years ago - hard to believe. Later I became an electrical engineer, and belatedly learned just how dangerous this setup had been. But, ignorance is bliss, and we never had any shocks, big arcs, fires or major problems or failures, and it actually did cut really complex shaped holes through thick steel and aluminum. A buddy and I built this contraption and won 2nd prize at a regional science fair. We attended a really small school, with teachers who really didn't understand (fortunately) what we were doing very well. We figured we'd done OK, since about 80% of the parts were junk/scrap, begged, or donated, and the only "guidebook" we had was a Popular Mechanics article. We bought the big capacitors from a motor & genset rewinding shop that worked on oilfield equipment. They got interested in what we were doing, and donated the mechanical fuel pump, a bunch of hoses, and a diesel engine filter housing and filters along with the fittings to connect it all up. They thought using an electric drill to drive the pump showed "ingenuity." We were pretty lucky to have people help us out with things like that, and the high voltage diodes. It's sure a long, long way from where EDM technology is today. I went to an industrial trade show once, where some EDM equipment was being demo'd, and told one of the sales reps about the Grade 8 science fair project. He had a good laugh, and told me we'd been complete idiots. Which wasn't really fair - we built it with almost no adult help, solved all the problems, and made a working machine that actually drilled a 1"-1-1/4" splined hole through thick steel plate. We nicknamed the beast the "Spitzensparken" for obvious reasons. My friend's dad was a ham radio operator, so he knew something about high voltage wiring and insulation. We were pretty lucky in some respects. How many school science teachers today would let a couple of 13 year-olds build a project like this in the school lab?. We had parents who kept an eye on things but trusted us enough to be careful when fooling around with what was a pretty crude rig.
Agreed, thumbs up for volume.
Man that’s totally awesome! I love that you got your inspiration from “Popular Mechanics”..... The internet’s of yesteryear!!!🤓😂😂😂 EDM would possibly be a cool way to fix a probe too a meteor. Drill and then weld. I’m wondering if you could torque steer the drill filament....🤓🤜🏼🤛🏼🤓🇦🇺
@Jim Baritone, what a story of genius at such a young age! You knew your calling. Typical of people who become engineers. I assume you are now retired and like me keep up with the journals and science news. Life is good! I knew my calling early in life (7th grade) and took a basic electronics course. I had no father to encourage me and help me make my dreams come true. The Armed Forces Schools gave me more training and I was able to secure employment at the White Sands Missile Range as an ET and later on an Engineer Assistant. I took college courses as necessary after returning from Vietnam to stay proficient and competitive. You did well Jim as a young dreamer and became one of the most coveted of career professionals in the world. Best of wishes!
Very cool and you sound about my age. Did similar crazy stuff from those mags all in the "lab" in my parents garage, they we always afraid I'd set fire to the garage and subsequently burn the house down LOL. I ended up going the scientist route but the thing I liked about what you said was about your science teachers. We had cool science teachers that were always "blowing thing up" and doing crazy experiments, I'd be a liar if I denied that they didn't have an influence on my later formal education.
Thanks for the essay.
Not to mention he very clearly walks us through every step, so that novice to expert is in full understanding of form and function, as well as what and where to go-to for parts and programs for running it. Impressive. He clearly watched ALOT of Mr. Wizard as a youth. Thank you Obi One....
I had need for such a machine several times in my shop life and only guessed that such a machine existed. Not till now has the concept been shown as being practical and affordable. Thank you. Opens lots of new doors.
I think hobbyist level EDM is going to make a large impact in the small/precision capabilities of the home shop
If you add in linear and oscillatory/elliptic processes you can end up manufacturing a LOT of nearly impossible to find parts.
still a long way to go to get precision out of it
It's more likely going to make lots of tiny little impacts of minimal force in the small/precision capabilities of the home shop
Seth Baker have you seen how much Bens setup costs? The baxedm psu is 2700 Eur alone! I dread to think what the total cost is - well out of reach of the average home shop
@@fourtwo7612 However it need not cost this much it is the current market that allows that pricing.
"In fact I have been able to drill through / ruin, every single conductive thing in the shop" lol ....
forgot to check if his camera
This has some useful automotive applications that I can see, namely adding safety wire to parts that didn't come with it. Very cool, thank you for showing this demonstration of your open source hardware table you built and the length of explanation of how and where you acquired the bits necessary to replicate.
Running an EDM drilling machine in my CNC-EDM Wirecut shop too makes me be even more impressed about you having build yourself such a machine DIY! It takes some really deep knowledge about electronics, the EDM process and also some decent building skills to get that done and finally to work! BIG RESPECT! WELL DONE!
The world deserves a collab between Applied Science and This Old Tony.
Completely agree! :-)
Now he can drill trough his drill.
I bet he's the kind of guy that never loses a chuck key.
If that's a requirement... I'm out. I own dozens, if not hundreds, and on a good day I can find about 7... give or take a few.
who uses Chuck keys? i just use a vice grip.
@@Unmannedair haha, good I'm not the only one.
ha! I wired one key to my dp and have another on a 6" piece of 1/2 inch galvanized pipe as an extension. Works great for getting the chuck real tight.
@@johnpossum556 good idea, but I probably still lose it. Haha.
This is amazing, I pick up my jaw after seeing the tungsten bit with some small niddle through it!.
Amazing work and amazing narration of the project. I want one! Thank you so much!
*Applied Science* I collect Niobium and Ferro-Niobium, would love to see you drill through the crystalline as well as solid bar forms using the EDM method. You are also the one guy who may be able to melt it in the home shop. Usually an electron beam welder type device is used to melt it, I had always wondered if a carbon arc mini foundry would be capable.
I EDMed a 1/2" wrench once while replacing batteries in a room sized UPS. A few hundred amps is all you need.
I know someone who welded a wrench using the same technique. Thinking about it, you could make a pretty easy high current welder/arc furnace using a few truck batteries.
My co-worker EDM-d about an inch off the end of her torque wrench, when tightening the bolts on bus-bars for a submarine battery. I believe it's ok to say this, because I found the specs on the internet: I'm talking about a 260 volt battery with a capacity of more than 10,000 amp-hours for each 2 volt cell. Each cell weighs 2,100 pounds. The total of 128 cells has stored energy of 2,600 kWh, and weighs more than 130 tons.
Everyone off the buss! It's pretty amazing what you can weld or vaporize with battery stacks. Used to be -48V for phone plants was The King here, but a lot of datacenter UPS battery plants can do it now.
i EDMed a new profile on my calipers with a 28v aircraft battery, you won't believe how efficient and fast that technique is
Out in the field, some people stick weld with 2 car batteries and jumper cables
I run Makino sinker EDMs and the capabilities of the machine is nuts! Super precise and some materials we also use for machining is Graphite/Carbon. There is different types of PoCo as well.
I love the level of detail that you include on the engineering of each specific component and process for those of us that love the minutiae.
The complexity and variety of projects that Ben works on is amazing. Always so thoroughly explained, too. Every video is a must-watch for me. Keep up the good work. ;)
That is the reason why you and others should continue to educate yourselves, learn proper English, be articulate and accurate in one's descriptions. That is only achieved when one has an extensive vocabulary. Learn from the example in the video and always strive for excellence. Perfection is NOT achievable ... Excellence is!
CNC milling for hobbyist ✅ Resin 3D printers for hobbyist ✅ Laser Cutter for hobbyist ✅ EDM for hobbyist 🤯
Not to mention the electron microscope that video got me amazed for couple of months
Just think if there was as much interest in hobbyist biology we'd have a home remedy for cancer by now.
@@professoreggplant9985 that would be gardening, homebrewing, etc.
TSK TSK... Forget about the Pressure Washer Water Cutter?
We are living in amazing times, but still can't wait for the fusion reactor for hobbyist so I could run all those amazing machines cheaper :D
I never saw drilling like this. Is incredible. Beautiful technology.
I have done it on some aerospace projects at the machine shop I worked at in Highschool. Were were not told exactly what we made as it was for the airforce. Was really cool to drill such timy holes through titanium
You made this so interesting. I couldn't pull away for a second. Thank you very much!
I remember you mentioning this process on one of my videos a couple years ago and I had since forgotten about it. This is crazy cool. I was just about to ask about how you even begin to figure out your feed rate when you mentioned the software does that for you. I really need to stop leaving comments before I finish videos. Looking forward to seeing how the wire EDM works in the X Y axis. Thanks for the great video as always!
The craziest part about wire EDM is that the top and bottom guides can move independently which means you can cut some crazy shapes with odd tapers. Even a shape with a square on one end and a circle on the other, with one singular cut
Of course ben makes his own EDM machine! I expect a fully functional fusion reactor by the end of the week. Edit: just wanted to plug this excellent Japanese tv show called supreme skills which is sort of a game show for Japanese scientists and manufacturing specialists. Heres an episode where they use a manual lathe and EDM drilling to drill through a pencil lead: kzhead.info/sun/o6eth7Sai3aYqJE/bejne.html Maybe you should give that a shot!

Electrical discharge machining drilling machine, wow that’s a mouthful.
I've been a EDM programmer/operator for 25 years... When I started my apprenticeship.. EDM was in its infancy. I run Wire, sinker and Hole popping machines. Even after 25 years.. I'm still learning new and interesting aspects of the technology almost every day. Wire EDM is the most accurate form of machining available today. We regularly achieve tolerances of .00005. Currently my company has 8 Fanuc Wire machines along with several sinkers and hole poppers.
.00005 what? attometers?
@@yosyp5905 fifty millionths or half a ten thousandths of an inch
@@fk6823 so, .00005 inches?
That's amazing! Could this be used on rocks?
@@speaklifegardenhomesteadpe8783 no. Only metals
Another fantastic video. I think it would be fun to drill across the diameter of a quarter.
I'd love to see that.
That would be awesome.
Party down, dude...
That would be cool
dammit Michael you beat me to it, although, I was thinking a nickle. Any coin would be awesome.
Excellent speaker - well spoken and explained
Thanks to your video, today i have successfully removed a broken screw tap from an aluminium heatsink. It was metric 3 and 6 mm long . I have done with a constant current lab supply with 10 amps and 24V. Rotation with a hand drilling machine. Thank you! Without you i don't think i could done it.
The level of application for this is insane.
42 Seconds in, had to stop and like. Wow, you drill through tungsten carbide with that ease
I love technology and people's ability to find new things to do and how far they can push it. Great video.
yes. but this is very old technology. i run EDM machines and my teachers back in college had
I haven't seen EDM in decades. Guess I really haven't found a need for it lately. We used carbon electrodes for drilling holes but we also had electrodes in special shapes which were used to essentially cut precision curved slots in hard to machine aerospace materials. Our coolant setup was very different from the one described. Coolant was similar to ordinary low pressure, high flow spot cooling for other machine types but the conductive coolant was different.
I'm new to your chann,this was my first vid,I'm impressed with your knowledge and I like the way you explain what it is your talking about,I'm fascinated with newer technology, this is just amazing to me and I appreciated your vid,thank you...
SO WELL narrated! Excellent learning.
Who would've ever thought that drilling a freaking hole can get so cool
Even the tiniest things in life have the biggest amount of engineering behind them, it's really interesting to investigate the engineering and science behind some basic things we take for granted. I'd definitely watch Technology Connections' videos on these kind of things as they are seriously awesome.
Dudes building megaliths.
You are at different dimension ! Very well done !
I’ve seen this before and forgot how interesting it was, thanks again. great video.
You do an excellent job of explaining all of this. Thank you!
This was an excellent presentation that was very well-spoken. The words used fit prefectly in the context of the video material. The extra effort put forth to inform is something many relevant viewers will not go without appreciating.
I know when I've stumbled upon something way over my head. Great work!
Could be a game changer for making solder paste stencils!!! This project is on my "To Do" list for sure, good stuff.
I had no idea this process was accessible. Thanks for the share.
You've got excellent and very unique videos, unlike many other channels that show the same YT videos over and over.
I needed that drill set up yesterday. Seriously. Very cool
Incredible content. You've got chops, AS. Thanks for sharing with us. Subscribed!
I was COMPLETELY enthralled with listening and watching this entire video! Thinking to myself "what to make first?"! Take care, 🤓 -Thomas
The topic was really cool and the Machine is awesome. How you explained it was over-the-top!
Nice. I started running 5-axis EDM right out of high school. Ran cooling ops on jet engine parts.
Well thats a nerd of a different color right there
Fantastic narration, explanation, work, and all the stuff.
We use a wire EDM at my workplace to cut certain metals and I'm learning how to operate the machine, but this video was great for explaining how the process works. I'll be looking forward to what you have to show with regards to wire EDM processes, but this drilling process was quite fascinating.
Don't even know what I'd use it for but I want to build one.
Ev3rMOr3 - more impressive is EDM wire cutting. You can do amazing things with it, cut some very complex shapes. I'd love to have one but I can't imagine this thing being cheap, even if I built it myself
@@richmac918 yeah I watched the guy with the edm machine that acts like a bandsaw. Cut was near perfect precision.
How about drilling .3mm holes through an aluminum front panel in any symbol configuration, so that you hardly see the holes until you shine an LED through them? Bonus points for voronoi stippling patterns, or a nice phylotaxis spiral for some subtle speaker holes. You can make them practically invisible to the naked eye with an ion beam but I'm guessing that's a little more involved.
Same here!
the way is the destination :D
This is very interesting. Thanks for sharing, and most of all, for the detailed explanation. Even those tiny bits only experience provide. Again, thanks.
And I thought I was a machinist because I use my DeWalt drill to drill a 1/16 hole in steel. This video was well worth the time and I learned so much. There’s a lot I don’t understand but I really enjoyed. Thank you.
You sir, are brilliant. I don't usually leave comments, and this has nothing to do with anything I would ever be involved in, but I found this very fascinating and articulate.

I am very pleased with OpenBuilds components.
Your video was very well done. Explanations were clear and complete. I don't need a small hole cutter, but I want one!
Now this is the kind of EDM I can get into.
Awesome, I'm so excited to see that you tackled this.
I won't pretend for 1 second to have understood everything that was going on.. But, it certainly is mesmerizing.. Thanks..
"half a thou of an inch" me: *screaming in metric*
"Half a thou of an inch" is quite understandable by anyone in mechanical engineering or anyone with a machining background. It is simply 1/2 of 1/1000 of an inch >>> or 0.0005". Then .0005 inch x (25.4 mm/inch) = 0.0127 mm. ...... Ed
Also common for engineering and machining is "mils" where "1/1000th of an inch" is also called "1 mil". So "1/2 mil" also is equal to .0005".

I do really appreciate your work and enjoy learning from your videos. Thanks
so well explained, i loved every minute of this
The local engineering shop that I frequented during my formative years on the farm had one of these units, and you could 'eat' out a broken off bolt/stud/whatever - it used what looked like a 1/2 horse electric motor, that had been reconfigured to be an electromagnet; the circuit ran through the armature and back through the work piece. When you applied the lever and brought the tungsten electrode into contact with the work piece, it energised the armature and the the electrode was pulled away from the work piece and created your arc, thus eroding the part a little. Repeated application of the electrode kept eating away at the part until it was (most;y) removed, allowing the broken part to be extracted. Magic!
Don Pollard no. magic is not real. electricity is real.
makes me think of lift-start TIG welding.
Working on an old steam engine--might have an application.
so thats how they do it! wow things you learn every day on youtube. thats really cool man. thanks for the vid
Got one of those machines in the workshop. It's really fun to prepare parts with 0.3mm holes for the wire cutting machine.
Hey, great thing about Openbuilds is that if you need to extend your Z axis to account for a longer probe if you don't want to cut them short, you can get a longer threaded rod and matching C-beam to extend the height.
This is brilliant! Also anxiously awaiting the EDM milling video. It is relevant to my interests.
Another wonderful video, you are like a video version of pre-1980's "Scientific American's The Amateur Scientist" you have kept me current (so to speak) in so many area's of (he-he-he) applied science. You are a diamond set in titanium, amongst hard core(lol) technicians. Thanks to you I no longer buy acetic anhydride, but instead, learned how to build a ketene lamp... with all glass construction except for the electrodes which are embedded in the glass to provide a perfect seal. Without your pointing the way it never would have happened.
EDM is one of the coolest machining processes. Very useful information, I may just have to consider following your instructions and build one for myself.
Just want to say i love all your videos. Keep up the good work!!
I am going to have to get one of these going asap. I have had so much trouble drilling offset holes in uneven surfaces. This is like the holy grail of holes. The Holey Grail.
I experimented with EDM using a 3d printer, and the door-bell EDM settup I saw on Jeri Ellsworth channel. Worked pretty well, and didn't need the pump assembly. Great way to remove broken drill bits stuck in your work-piece.

Nicely done video, you explain things very well. One thing I might suggest is making the bracket that holds the out of water ceramic electrode easily removable. That way you can insert the drill rod into that ceramic electrode and then reinstall the electrode with the drill rod already in place. I can see the concentricity issues at minute 20:17 but, that wobbling is between the upper electrode and the chuck. I don't see the wobble problem at 20:32. Anyway, just a comment from the peanut gallery. Great video I have more knowledge than I had yesterday and that's a good thing.
я вас растрою но вращение при такой обработке не требуется, вот если бы показали как делается отверстие спиральной формы имеющей конус еще и например в форме звезды... вот тогда я бы поверил что вращение нужно, но при таком вращении нужен прецизионный шаговый двигатель с безлюфтовым редуктором. Электрод не требуется часто менять, так что делать быстросъемным не нужно, да и горит сам электрод достаточно долго.
From decades of working with analog power supplies filter and shielding and low noise ultra fast soft recovery diodes help a great deal . Wire management also reduce antenna effects of un-shielded wire . Faraday cage does work also . Enjoyed the video keep up the fine work.
I went to a votech to learn and the die sink was my favorite machine at that time in mid 90s. Long before 3d printing . We only used electrodes and they didn't have any spindle or spin at all for that matter. We used graphite or brass. The graphite was very easy to shape. I did some really complex burn with steps and about geo shape you can imagine. EdM wire machine was so amazingly accurate and could such a great tolerance.
You're awesome! Just ONE of your videos achieves more than I've achieved during my whole life. Truly magnificent :)
Fascinating, this EDM process is new to me. Thanks
