[@robertallaire432]

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.

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 KZbinrs like me. Thank & Arigato for sharing with us! Much Obliged. just Awesome

[@michaelmclaughlin8208]

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!

[@tranpham6151]

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

[@chrisschmitt3860]

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

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 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!

[@galaxiedance3135]

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.

[@jisakukobo]

Thanks for your comment. Being able to sharpen the drill yourself will save you money. It's not disposable.

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. :)

[@Luzifer4m0k]

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 👍

[@jeanphilippepoirier6130]

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.

[@Thinkle911]

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!

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.

[@jpnguyen91]

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

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

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 ...

The last bit of grinding on the tip is what we were taught and its called thinning the web it makes all the difference. Some drills can be bought with this already done from new but they are quite rare. especially as all our manufacturing has moved to China and everything is subsatandard now. The only ones i have seen with the web thinned were ones from the US but they had no brand name as i think they came off a military ship. They were the best drill bits i have ever used and held there edge for way longer than all other brands i have used only drawback they were very hard so they were best used in a drill press rather than by hand as they tended to snap if you were a bit careless.

[@mishu0102]

thanks for the useful tip. so, what are the two degrees? 10* and 30*?

[@marciosquilassi3392]

Great! 👏🏼👏🏼👏🏼 What angles were used to sharpen the drill bit, please?

[@MysticalDork]

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.

[@MrRackinroll]

@@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.
