- Hello friends.
This is the official channel of JSK-koubou.
Here you can find many interesting videos about homemade machinery, woodworking projects, plans and life hacks.
I made a sharpening jig that makes the drill bit sharper than new drill.
This jig will be distributed free of charge to those who have purchased a grinder stand plan.

I hope you will share my videos with your friends!
Zen-Handcraft at its best! It invites for meditation while crafting 🤪 Any chance of adding the Dimensions, Numbers etc. subsequently or in retrospective?
Bonjour, Oui bien évidement et tout le plaisir de regarder les vidéos
Bonne continuation
Et merci a vous
Que fácil y que ingenioso es, voy a copiar tu plantilla ,gracias por tu consejo.
All your videos are great! Have you any ideas for making a jig for sharpening flat bits?
Идеально! Просто и эффективно. Пожалуйста, можно сообщить параметры и углы заточки?! Успехов в творчестве!👍
Thank you for inspiring me to do better.
While I strive to pay attention to detail and toward achieving a standard of quality in the things I create, it is in the process of making that I try to multitask, to rush through the set up of jigs and fixtures which result in ad-hoc solutions. They serve to solve the need at the time but often not much more. Your Zen-like approach toward creating these tools, and how you incorporate precision and accuracy into every step, is where I want to be.
I too would like to see more in the way of dimensions and details, but I understand that this information is what you are selling at your online store. What I would truly like to know is the make and model of the store bought tools that appear in your videos. For example the circular saw used in your wall mounted track saw is often used to cut aluminum as well as other materials. The type of blade and the speed of the saw (RPM) are very important considerations that I believe could be shared without diminishing the sales of the plans. Additionally in this video (5:03) the drill bit / countersink combination used in securing the block to the base was something I have not seen before. I am sure that the manufacturer wouldn't mind being mentioned.
Again, thank you!
This guy is such a Practical Genius... His love of wood marries technology with simplicity and effectiveness. If there ever was such a thing as Shop-time Machinery and practicing Buddhism and Philosophy while Meditating on Carpentry, this is the only Gentleman that makes me feel like I'm in a Bliss while watching him creating something so superb and simple that this has got to be the new Nirvana Carpentry made in heaven! And I love how clean and neat his hands, fingernails and shop & tools are... A True Craftsmanship and A Gift to TH-camrs like me. Thank & Arigato for sharing with us! Much Obliged. just Awesome
Finally someone that will address basic shop practice. Very good take on bit sharpening. 47 years as an auto mechanic and automotive machinist. I use a different but similar approach, but this jig exemplifies the care to produce the proper geometry to achieve a bit with the proper relief to function properly

This is the best video that I have seen!
The cutting edge exactly and right angle compare with original drill bit!
Thanks so much .
I wish I knew what my father knew. He was a magician when it came to sharpening, didn't need much in the way of jigs, mostly free hand, including the twisting and a double angle. That was along time ago - 50 years. One time I was doing something as he came home, in a suit white shirt and tie he sharpened my tools to speed up my work. When I got to wood shop I was better than the grade 9 teacher, and I could prove it by dragging a sharpened chisel over a wet paper towel cutting the paper ad the teachers chisel dragged the paper along!

Just did that with my grandson when we reconditioned a no4 plane for him and i showed him how it cuts paper without tearing. And i have been sharpening drill bits for 50+years too.
Every time I see you make another tool or jig with the tools and jigs you’ve already made I just cannot help but take my hat of deep to you Sir! They work flawlessly and meticulously. You’re an amazing craftsman!
es una artesana es una gran mujer 👍
Hello dear friend - A sharpening drill is the most complex thing in mechanics! You're using an unconventional system, but one that works. Standards specify precise angles that make a good compromise between sharpening quality and durability. Your drill sharpens well because the countersinking angle (dépouille in French) is very important, more so than the standard 2° for steel. For us, having to sharpen a drill more often is not as much of a problem as it's in industry. That's why I'm going to test your system, because I've been sharpening my drills "hand in the air" for over 50 years. The only drawback is symmetry, which is never perfect. So thank you for the lessons you so kindly provide. Bravo again, you're a master of ingenuity.
Your efficiency at work is astonishing, sir
That's pretty cool. I just can't help but think I do a darn good job sharpening bits free hand on a table grinder.
Basic training for a fitter, had to learn this at the very start of my apprenticeship back in the mid 70's. Also the use of pilot holes lol
Muy buena plantilla ! Te felicito👍
Note: I feel sorry for all those 750+ who gave 'thumbs down' to this or any of Mr. Koubou's videos. It must be horrible to see something so simple & creative and instead of feeling appreciation, just feel envy and disdain. Everyone has the capacity to create and be original but those who don't see this and many other Crafts as a Natural Ability, are selling themselves short and undermining their capacities. I'm lucky to be one on the greener side of the street. There are No Limitations to the Self. Only those you impose on your own. Seth
perhaps it is because the link to buy the plans is nor available or it´s very difficult to find...
Excellent idea and great video showing the basics for drill bit sharpening. Thanks for sharing. Regards from Spain
Un trabajo perfecto, mis felicitaciones JSK-koubou
Thank you for sharing this good ideas, eaziest way with wood.I il make some by myself.
Nice Work! gorgeous, as usual..., Any link here to buy the diamond disc ?
NO TENGO PALABRAS PARA REFERIRME A ESTE AMIGO. SIMPLEMENTE. INCREIBLE LO QUE HACE Y CON CUANTA PULCRITUD. GRACIAS.
Good work as always. We shared this video on our homemade tools forum this week :)
Outstanding jig, any sharpening tips on brad point bits.
Great video. love the way you show every step.
Thank you! Very helpful! And very beautiful video!
Sir your work and your skills are awesome and so detailed 👍 👏
beautiful and precise work all done with common tools and materials
I greatly enjoy watching your well-produced videos and excellent workmanship! I'm in Canada and I have been looking for a diamond wheel like you use in this video. So far I'm not finding one. Anyone have a source for that disc or one similar?
I have already successfully used a diamond wheel intended for cutting concrete.
Koubou san, you rpm of the drill are way to high to drill holes in this metal thinkness. The drill will get to hot, you should either cool during drilling or decrease the rpm. Much better for your drills, less sharpening to do. :)
yes, thats right. the easiest way to check it on the fly is, watching the produced chips. if they are small and crumbly the rpm is to high. if they come out as spirals you are on the right way. and when these spirals get very long, you hit the perfect spot of rpm and feeding pressure 👍
This video shows us how to reuse the old drill bit that’s main thing!
Don’t worry how to drill a thick metal! He knew!
Thanks for sharing those tips and the make!
A friend has a serious workshop, with a Cincinnati Cutter grinder & racks of wheels and jigs - for milling tools. Yet he sharpens drills by eye on a 2 wheel grinder and they are lovely. It's an art. I wish I could do it.
If you work at it enough you can.
Believe or not. I really want to know more creative ideas. So I search for more clips like this. But honestly I was be able to grind free hand milling bits amazingly. I think not every time I could be able to do like once I had sharpened a 3/8 endmill and tried out It yielded a slot of .372 neatly. Again practices could help you to improve the skills. I finished my apprenticeship just 15 months after 2 years of college education for tool and die maker
You should sell all your self made tools and jigs in kit form I’m sure they would become the must haves of the diy market.
Fantástico , muito bom , Very good, Brasil 🇧🇷🇺🇸😀
Sorry for not translating, pero sos un "capo", excelentes tus trabajos, amazing...
Gracias por el video muy interesante , me encanta tu taller y tus maquinas , me he suscrito para seguirte .
Thanks very much for the nicely sharpened steel drill bit demonstration performing even better than a new one. But all these machines and gadgets are not available to each and every one of us. Therefore some other option should better be suggested/guided to us all!!! Thanks in advance
Upaaaa!!!! Señor, no deja de sorprenderme!! Muchas gracias...
切れ子が長く綺麗に切れていますね！
素晴らしい👏
新品と同程度に研磨できるという動画を撮るつもりだったのですが、予想に反して新品よりも切削性が高くて驚きました。
Great video & a good reliable jig for the work shop.
When I was an apprentice tool maker (many years ago) every Monday morning I had to sharpen all the drill bits in the tool room. These included fractional, metric, number & letter drills from 1/16 to 2 1/2 inch. It took me several hours but it taught me how to sharpen a drill.
Stay safe & keep on smiling.
I'm astonished from your art, you are absolutely a genius. You inspire me every time, every single video, thank you so much
Looks like you were able to make the drill center cutting. Most twist drill are not center cutting. The sharp edge does not reach the center. That explains why you re-sharpen drill cuts better than the new one. Regular non-center cutting twist drills does not cut the material in the middle but pushes it away. This is why is better to start with a small drill and go progressively bigger.
Awesome project! Keep them coming.
And also to apply the right speed. For the test at 12:50 the speed feels and looks quite high.
Great job perfect geometry. Very beautiful diy tools you have made
I start small with drill bits (with steel). Using three or more bits smaller than the hole you want and working up to the desired size. This and using a center punch before you drill seems to help to keep drill bits lasting longer ...
But that's the whole point of the easements on the back sides. You don't HAVE to use multiple bits.
@@garychandler4296 is that the hole truth
@@ronaldoball7497 I wholly think so!
@@garychandler4296 other wize it's a bit pointless
@@ronaldoball7497 But I do get your point...
Very cool ! If I do it, I 'll add a "screw" to set the length to sharp. With this , when you turn your bracket to change of side, you are sure to have the same result, and don't need to check with your rule.
Thank you for this new beautifull tool !
Um Like com louvores !
Perfeito ! 👏👏👏👏👏👏👏👏👏
So that's how you get the drill out of its packaging!
Point taken
wow i never saw a drill bit sharpened like that ! omg that is so OP. Question : does your Ryobi grinder has some sort of RPM adjustment ?
Excellent! Je savais qu'on pouvait les aiguiser,mais je ne savais pas comment : )
Merci du partage,Bye
That's the best thing I have seen today, it was beautiful to watch.
Nuevamente gracias por enseñarnos a aprender y regalarnos de su valioso tiempo. Maestro de Aguascalientes México Francisco gamez un abrazo muy fuerte y saludos cordiales bendiciones para usted y toda su familia es usted genial 😀👍👍👍👍👍👍👍👍👍👍
Holding the drill bit in jig helps in getting equal taper on both faces of the drill bit. Else as you drill, hole moves to one side making center punch marking ineffective.
I am always happy to see all your videos I am a big fan of yours work thanks a lot
wow - I don't seem to get this right, I just tend to sharpen the drill away, the smaller the bit the more I mess it up - yours seem so effortless. What are those angles you use I cant seem to pick it up off your ruler when I watch the clip.
The jig is at 59° to the face of the wheel and the top hole is 10° for the cutting edge and 25° I think for the relief angle.
@@konnan216 thks man
Would a stop help to get consistent taper on the tip? A stop which limits the travel of the block with the drill towards the grinding disk. That also ensures that the very tip is also at dead center.
I think it would be easy to add a stop that you set by hand after making the first pass.
very usefull jig.what disk do you use for sharpening the hss?
Zen-Handcraft at its best! It invites for meditation while crafting 🤪 Any chance of adding the Dimensions, Numbers etc. subsequently or in retrospective?
Very impressive! I like everything you build, including your grinder and the vertical panel saw. Do you have videos for those? I’ve recently built a pole barn with a wood shop & now after about a dozen years wanting a vertical saw, I now have room for one. I like your setup for your drill press good for drilling small parts. You’re very innovative. Thanks
He does. Search "panel saw" and "angle grinder stand".

@@CharlesOVieni I can see why you may think that, but definitely male. If you watch him making a larger project such as the workbench or perhaps one of his RC birds you will see he is a man.
Добрый день. Молодец!!! Супер. Видно ,что не рукожопый! Есть чему поучиться .
Great little project. Lot cheaper than buying a drill sharpener at $300- $500. Particularly when your hands and eye sight are not as good as they used to be. Thank you for sharing. Domo Arigato. I believe is correct.
Классная работа! Good work!
now i know how to sharpen a drill bit, thanks for the demonstration
Thank you for this.
Your work is beautiful.
I would wonder, though, if the drill speed was a bit too fast for the size of drill.
This is the best drill bit sharpening jig I have seen on TH-cam. I will make one, but I cannot see well the angles you scribed on the drill guide support block. The first appears to be about 11 degrees and the second one about 30 degrees. Can you verify these angles for me? Thanks!

15 degrees each side on the cutting edge
Cordial saludo y mi deseo porque tenga éxito en las actividades que emprenda.
Nice and simple. Good job.
Here is another idea. Put a stop on the front of the jig to be sure the tip is in the middle.
By making the cut on the point of the drill you cheat a little. This way you don't have to pre drill with a smaller diameter. Remember the point of a larger diameter drill bit is not cutting. Without pre drilling the tip of the drill is just melting th metal.
Maybe you can make a jig for cutting the second face on the tip?
You know it's koubou when the product is better than new
Except for the fine tune grind on the tip, I achieve the same double bevel grind using the craftsman jig model 6677. Makes nice chips. The wood jig is pretty creative though!
When I started my Tool & Die Apprenticeship, I was shown how to sharpen a drill by hand, cut the web and everything else. Then I was told to sharpen every drill in the shop and check the size of the hole it makes in a scrap metal piece to make sure that they cut correctly. So after doing that for a couple weeks, I became very good at it. Good enough that I don't dare use any tools for sharpening. I do it by hand and my drills work amazing. I did use that gauge at the start but after a while, I was getting it perfect by eye. You'll never learn the proper technique by hand if you don't practice. Takes some time but it's well worth it.
Thanks for your comment.
Being able to sharpen the drill yourself will save you money.
It's not disposable.
Muy buen trabajo pero un favor cuales son las medidas de los cortes de la madera para hacer esa herramienta de sacar filo a las brocas se ve genial saludos desde tlaltizapan morelos mexico
I was a machinist back then and used to drill few hundred holes on a mold base(intergrated circuit mold) and its 40 mm thick and 60mm thick for bottom base..i just used manually when grind the drill bit that is 3.5 or 4mm(ejector holes) ..just share my experience..now all going into the drain as im a only a driver now
Cordial saludo y mi deseo porque tenga éxito en las actividades que emprenda. Por favor, puede informarne cuántos metros cuadrados tiene su taller?
Excelente tarde maestro como siempre buen trabajo o más bien excelente trabajo lo felicito y gracias por compartir saludos
I also have been sharpening drill bits by hand for 50+ years. It takes practice and motor skills that are akin to riding a bicycle. Once you get the hang of it, it's easy. BUT......, when I have to sharpen a left handed twist drill, I feel like a kid again, still trying to get the motor skill of sharpening a backward drill bit. I can do it, but not as easy as the standard bit!
Excelente video.
Me puedes decir que disco de la amoladora utilizas?
Muchas gracias.

hi again
what kind of blade do you use?

Ótima a fiação, melhor que a broca nova,parabéns!
I wonder if Jisaku san will ever find himself in need of a table saw. Much love
genius - and you make it look so easy!
What did you use to Slow down the Grinder???
Fantastic work, dude! Really great jig! 😃
Stay safe there with your family! 🖖😊
Красивый инструмент, красивая работа!
Хорошее приспособление для мастерской!!!
Только стоит установить ограничители, чтобы сверло при заточке не выходило больше необходимой длины.
А ещё нужно добавить кондуктор установки сверл в оправки.
Так ему просто нужно сделать штук 5-6 оправок под основные ходовые диаметры свёрл, маркировку нанести и всё...
Для заточки свёрел и фрез существуют специальные станки, и лучше их ничто и никто заточить не может, все остальные заточки равносильны заточке "на глаз".
Здравствуйте, я много лет так затачиваю сверла, но только на глазок, Ваша приспособа - крутая, класс!!!
"На глазок" всегда, как-бы ни старались будет отличие в заточке сторон, а следовательно и ускоренный износ сверла в процессе работы...
Да, приспособа полезная.👍👍 Но не хватает упора на "ползунке" для симметрии. Тоже точу "на глазок", года с восьмсятчетвертопятого ))), для бытовых целей нормуль, иногда даже точнее магазинных чиновских. А научил так затачивать вовсе не трудовик, а папа одноклассника, на "практике".
@@TVF-72 чтобы "на глазок" был точнее, надо сначала сверло "затупить" на оборотах (задать центр и угол)..
Great work, please, why you did those two final grindinng close to the center ?
見事な方法で実行されたドリルのクリーニングを改善するための素晴らしいアイデア。 もう一度ありがとう、ジサク。
☺☺☺🇮🇩🇮🇩🇮🇩
What disc do you use to sharpen these drills? What name should I be looking for?
Great! 👏🏼👏🏼👏🏼
What angles were used to sharpen the drill bit, please?
They're not super critical, as long as the cutting edge is in front, and nothing behind it is high enough to rub.
An included point angle of 118 or 135 degrees is common, with a primary edge angle of 10-20 degrees and a secondary relief angle of 25-40.
Steeper angles will make the drill cut more aggressively, but the edge will be more fragile and prone to wear or chipping. Shallower angles won't cut quite as fast, but should last longer.
@@MysticalDork I could be wrong but he might be wanting to sell that info. Why else would he not give the proper info when that would be the primary info require to make the jig work. I know this in my head from all the years do machinist work.
@@MrRackinroll that’s just standard drill angles. Nothing secret there. It’s printed on the packaging of most drills.
I wanted to ask you this question
great video and love your Workshop and use of DIY wooden jigs that is a big part of your success 👍
I understand the point u make when comparing a "sharpened vs. New" drill bits.
I noticed the twists were between on the "new" bit, so are they both comparable in the "type" of materials they're used on? I saw one video saying that the more twists are for softer materials.
Me gusto la construcción de la sierra de corte vertical,si pudieras entregar mas detalles ,el afilado de las brocas sale mas rapido comprar de repuesto.
Ese metal no se taladra a esa velocidad, se taladra a mucha menor velocidad, es hierro pero es aplicable al acero, bronce, latón, aluminio.
A altas velocidades la punta de la broca se calienta tanto que incluso se puede poner al rojo vivo reblandeciéndose la misma y perdiendo todo el filo cortante, en fin... que nadie se enfade amigos.
De todas maneras esa herramienta para afilado de brocas esta muy bien diseñada, buen trabajo y buen diseño.
Recomendación:
El soporte de la broca a afilar debería de ser el mismo diámetro que la broca, ese soporte tiene como minimo el orificio de 9.5 - 10 por lo que la broca baila a no ser que la fije el tornillo, yo lo habría echo lo suficientemente justo (una o dos decimas de holgura max.) el habitáculo como para que la broca encajara como un dedal e incluso el soporte lo haría de aluminio o incluso de acero endurecido y ajustable horizontal, vertical y lateralmente.
En fin, me gusta el diseño, yo de ti lo puliría un poquito mas y lo patentaría, yo lo haría.
Saludos
