How to Sharpen Drill Bit / Drill Sharpener tool 

I hope you will share my videos with your friends!

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 RU-vidrs 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

Desde Argentina, Ud. es un capo. En cada proyecto que hace. Gracias !!

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!

This is the best video that I have seen! The cutting edge exactly and right angle compare with original drill bit! Thanks so much .

Excellent idea and great video showing the basics for drill bit sharpening. Thanks for sharing. Regards from Spain

Thank you for sharing this good ideas, eaziest way with wood.I il make some by myself.

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.

Your efficiency at work is astonishing, sir

I'm astonished from your art, you are absolutely a genius. You inspire me every time, every single video, thank you so much

NO TENGO PALABRAS PARA REFERIRME A ESTE AMIGO. SIMPLEMENTE. INCREIBLE LO QUE HACE Y CON CUANTA PULCRITUD. GRACIAS.

Un trabajo perfecto, mis felicitaciones JSK-koubou

Good work as always. We shared this video on our homemade tools forum this week :)

Muy buena plantilla ! Te felicito👍

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 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!

Great job perfect geometry. Very beautiful diy tools you have made

Fantástico , muito bom , Very good, Brasil 🇧🇷🇺🇸😀

That's the best thing I have seen today, it was beautiful to watch.

Gracias por el video muy interesante , me encanta tu taller y tus maquinas , me he suscrito para seguirte .

Thank you! Very helpful! And very beautiful video!

Outstanding jig, any sharpening tips on brad point bits.

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 !

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

Nice Work! gorgeous, as usual..., Any link here to buy the diamond disc ?

Thanks for sharing those tips and the make!

Upaaaa!!!! Señor, no deja de sorprenderme!! Muchas gracias...

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 😀👍👍👍👍👍👍👍👍👍👍

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.

Excellent! Je savais qu'on pouvait les aiguiser,mais je ne savais pas comment : ) Merci du partage,Bye

Great video. love the way you show every step.

Sir your work and your skills are awesome and so detailed 👍 👏

I am always happy to see all your videos I am a big fan of yours work thanks a lot

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.

beautiful and precise work all done with common tools and materials

now i know how to sharpen a drill bit, thanks for the demonstration

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

Excelente tarde maestro como siempre buen trabajo o más bien excelente trabajo lo felicito y gracias por compartir saludos

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.

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. :)

You outdo many things. Thanks for sharing your talents with us kind Sir. あなたは多くのことをしのぐ。あなたの才能を私たちと共有してくれてありがとう。 Anata wa ōku no koto o shinogu. Anata no sainō o watashitachi to kyōyū shite kurete arigatō.

Cordial saludo y mi deseo porque tenga éxito en las actividades que emprenda.

Um Like com louvores ! Perfeito ! 👏👏👏👏👏👏👏👏👏

Ótima a fiação, melhor que a broca nova,parabéns!

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?

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

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.

Sorry for not translating, pero sos un "capo", excelentes tus trabajos, amazing...

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.

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?

GRACIAS POR COMPARTIR TU INGENIOSO VIDEO. SIGUE COSECHANDO EXITO. ATTE. MOY.

genius - and you make it look so easy!

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.

Felicitaciones, buen trabajo

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.

Zen-Handcraft at its best! It invites for meditation while crafting 🤪 Any chance of adding the Dimensions, Numbers etc. subsequently or in retrospective?

SALUDOS DESDE ECUADOR...MUY BUENA IDEA...

Quisiera tener la paciencia y buenas herramientas para lograr este nivel de conocimientos. Gracias por este y todos tus videos

Классная работа! Good work!

Cordial saludo y mi deseo porque tenga éxito en las actividades que emprenda. Por favor, puede informarne cuántos metros cuadrados tiene su taller?

Добрый день. Молодец!!! Супер. Видно ,что не рукожопый! Есть чему поучиться .

Very well done, thank you.

切れ子が長く綺麗に切れていますね！ 素晴らしい👏

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

Красивый инструмент, красивая работа!

great video and love your Workshop and use of DIY wooden jigs that is a big part of your success 👍

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 ...

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!

I love how you make your own tools.

Is perfect perfect!

Nice job thinning the drill point.

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

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.

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 ?

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.

Muy buena la idea, felicitaciones !!!

Another good video thanks for sharing

Re-bueno ese sistema de afilado Gracias

esse profissional da maior categoria. 👏👏

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!

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.

Lights action camera editing timing filmography ,incredible

Excelente, siempre he querido aprender a afilar brocas, es un gran sistema pero no dispongo de medios para poder hacerlo, gracias por compartirlo pero lo voy a intentar

Sweet, exactly what l need

Complete tools nice working.

I wonder if Jisaku san will ever find himself in need of a table saw. Much love

Excelente video. Me puedes decir que disco de la amoladora utilizas? Muchas gracias.

Thats pretty clear, the nice long chips show the bit you sharpened cuts better.

You know it's koubou when the product is better than new

So that's how you get the drill out of its packaging!

👏👏👏👏👏👏👏👍 Das scharfe ist toll... Besser als ein neuer bhorer.👍👍

This guy has got jigs for everything !!!

I got many worn drills, but had to recycle them. I wish I have your skill to make these tools.

此示範秀很清楚，thanks lot,

Отличная приспособа и сделана очень аккуратно!Excellent fit and very neat!

thanks for sharing the video

This is the best drill bit sharpening jig I have seen on RU-vid. 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!

Вы удивительный мастер !!!
