- Drill bits become dull over time, so they need to be sharpened regularly. Many people want to learn how to sharpen drill bits. That's why we showed you how to sharpen drill bits in this video. If your drills are dull and no longer drill well, be sure to watch this video called how to sharpen drill bits.

That jig will give a lip relief angle (not the same thing as the tip angle) of 30 degrees, which is too high for most purposes. That relief angle will give a very aggressive cut in softer materials, but a smaller relief angle of about 20 degrees would be preferable for drilling steel, and perhaps as low as about 10 degrees for harder steels.
Надо учиться заправлять сверла на глаз и это самое верное,чем заморачиваться.
На заводе никогда не видел никаких присоблений,просто надо иметь опыт!
Труднее всего было качать пальчиком из стороны в сторону, но я старался! Теперь все свёрла острее бритвы!
Чувак реально своим пальчиком выбешивает
the old man who taught me said cooling bit during sharpening was just as important as sharpening. Bobby Cook was one of the best!
Correct... too hot and you draw out the temper and you're dished as the bit will dull quicky once back in use. The rule of thumb is to make sure the bit never gets too hot to hold even at the end of the bit where you're sharpening it. In other words... short grind, long coolant dip, short grind, long coolant dip, short grind, long coolant dip, and so on. Best wishes!

Grind a relief cut on the trailing edges and the bit will cut faster and cooler with less pressure. I often only need to hand tighten the chuck when properly sharpened.
Sumner Nissen taught me how to sharpen drill bits way back in 1974. He was ever so patient. I screwed up a lot of bits, but when I finally got it, I was on the Moon. He then made me fix the bits I screwed up. Lesson learned. Now, after all those years, it only takes me about 2- 3 minutes and the drill bit is as sharp as new. The art of drilling is more than making a hole. ALWAYS KEEP A COOL TOOL.

Great 'how to' video. Have some drill bits in my shop that I can now 'save' and re-use. Thank you for posting.
I was taught how to sharpen drill bits back in 1966 by hand on the grind stone. After a few you get the "eye" for it. I worked as an auto mechanic for 52 + years and knowing how to sharpen drill bits is a must. All I ever bought for sets at work were Harbor Freight. IMO they are just as good as overpriced drill bit sets and a lot cheaper to replace. Last place I worked one of the mechanics did an excellent job of tearing up his $350 set from Snap-On Tools trying to drill out a broken bolt(which he also seemed to be a expert at snapping bolts and studs). Ten minutes with the cheapo Harbor freight bit I was done. Fancy stuff is great but ya still need common sense.
The proper speed and a lube will make a big diff. on success.
Always better to have spare tools than to have a single high end one. Life time warranties are great but you still haven't got what you need in the time it takes to get a repair or replacement. In a machine shop, that's not a good thing. Gotta be quick.
Fully agree
me too, easy when ya know how. i use my belt sander.
Soooo true. I laugh at people buying more expensive tools which cannot be sharpened. An expensive bit lasts 2 times or 3x times longer. That is what the package says. And the last 30% of the lifetime it does not even cut optimal anymore but you keep using it because it was the expensive type. I learned how to sharpen my drill bits, and never buy any drill larger than 6mm, 1/4" The thinner ones unfortunately break sometimes.
Well done! Vids that show people how to save money are the best!
Très bonne idée 👍 bravo !!!
This how I was taught to sharpen blades in mechanic school back in the 70s. Works great!
Aaahhh.. But did you learn how to "wag" your finger at the same time..... I can't believe that people think all this measuring and angle finding is how to do it...
Your instructions are very detailed.
Сверла так не точатся тем более по железу
I really like your sander set-up! Care to share how to make it? The motor sounds like a bench grinder/polisher.
Караул, детский сад) Сверло затачивается "на глаз", угол заточки зависит от твердости материала который нужно будет сверлить. Чем мягче то что нужно сверлить (дерево, пластик), угол заточки делается поострее. Чем тверже материал тем больше угол заточки до предела - 120'. Затачивать угол заточки легко "на глаз", контролируя симметричность угла перьев сверла поглядывая на обрабатываемые стороны перьев на белую поверхность сквозь кольцо сложенных пальцев руки в жест "Ок"
Das Schleifen an der Schleifscheibe des Bohrers bedingt zwei Bewegungen gleichzeitig, Drehbewegung und eine Schwenkbewegung damit der Bohrer einen Hinterschliff bekommt. Die Bewegungen habe ich auch bei ihnen gesehen. Den Spitzenwinkel an der Spitze des Bohrers soll 118° betragen, also 59° (60°) seitlich zugestellt zum Schleifstein. Beim Schleifen am Teller ist ihre Bewegung allerdings nur als Drehbewegung ausgeführt gewesen, so dass nach diesem Schleifen der Hinterschliff verloren geht und der Bohrer einen falschen Anschliff bekommt. Ein Tipp noch, ich schleife die Querschneide in beiden Spannuten an der Schleifscheibenkante etwas kleiner bei größeren Bohrern, weil die Kraft zum Bohren ins Volle dadurch geringer ist.
Your method is also very good, but I will make it easier for everyone, thank you for sharing.❤
0:49 ЭТОТ угол зависит что ты будешь им сверлить. Для мягко металла нужен угол 90 и до 60 градусов. А для стали надо от 110-130 градусов. И тупое занятие это для каждого сверла белать оправку. И не стоит слишком сильно заднюю часть (не рабочую) заваливать.
...yeah!..that's right!...now smarten up!...cheesescrisis!...why do I need to tell you everything again?...😅...
@@JohnViinalass-lc1ow Are you so smart that you teach everyone with your stupidity?
вы имеете ввиду ,что он подкручивал сверло по продольной? смотрел, что просто реж кромку ставят горизонтально и с упором на палец по наждаку ведут вверх - на себя от реж кромки по задней поверхности ,наклоняя хвостовик вниз с соблюдением угла. Не знаю правильно или понятно написал?
Классно,доходчиво и просто.Успехов.
Sharpening drill bits must have good skills like my friend, Thank you for sharing
genral 825 drill sharpener jig, perfect sharte quick cheap
I am so impressed with these fantastic and useful tips!
Superb design but very simple. This is grand master stuff. Kudos.
Always use the correct drill bit for the job, and always use lubrication when necessary or when required such as when drilling masonry and/or metals. Heat will ruin your drill bits no matter how sharp they are. Follow these steps along with this tutorial and you will be using the same set of drill bits for years to come. Awesome tutorial!
You do not use twist drills for masonry you use masonry drills that have tungsten inserts.
0:10 I already turned on a pedestal grinder, sharpened the bit, and turned it off again. Learn how to sharpen a bit, how a bit works, and you will never fear it again.
You don't use lubricants for drilling... you use a cutting fluid. You are correct about excessive heat though. Best wishes!

Bits are for wood just drill for a twist steel drill
Use a smaller drill for pilot hole first is the best way to protect your drill bits.
Thank you for sharing your simple DIY way of sharpening drills. My Dad used something very similar for nearly 50 years, so know this method works. ha-ha
Every time the finger popped out I expected him to
show how effective it was at industrial manicures.
Thank you 😊
Useful information, thank you for the video
I’ve done it like this for 35 years, at least the part on the grinder. The part on the sanding discs isn’t necessary. An important bit missing, is the importance of getting both cutting edges exactly the same size. Even a few tenths of a mm difference will decrease the efficiency of a drill bit in a major way.
Если руки кривые и не оттуда,оно конечно нужно 2 десятка приспособлений и станков) по факту имеем заваленный угол и отожженную подточку,ну ничего пенопласт можно сверлить :)
Buy a drill doctor. So worth it and they do split points also. I am a machinist and when I worked for an aerospace shop we had a multifangled machine to sharpen drill bits but even that thing did not do split points. We eventually hired a guy to stop by every few months who had some sort of machine made out of a lathe and that guy could put a factory level sharp point and do the split points. he was worth it. Now I have the better upgraded drill doctor. One thing about those, get a finer grit grinding wheel to do the carbide bits not the coarse wheel. On any bit from around 1/8 up I can get a darn good point. Smaller bits are dicey and hard to do.
1 угол заточки сверла если быть точным 118° . 2 я в руках заканчиваю сверло за 5- 10 секунд. Это просто навык за 35 лет работы с металлом.
Хорошо бы ему упомянуть про задний угол. Это тоже очень важно.
Лет 10 наблюдаю точно такие же способы заточки на ютубе. Ролик 2023 года. Новатор ты наш !!
Рукожопость это эпидемия=))
THE PROPER ANGLE FOR A JOBBER LENGTH DRILL IS 118° AND IF IT IS SHARPENED PROPERLY EACH FLUTE WILL CUT EQUAL SIZE CHIPS. ALSO USING THE SIDE OF THE WHEEL WILL PRODUCE A BETTER FINISH.
You should never, _ever_ grind on the side of the wheel! The Internet is full of people posting dangerous advice.
I was done at the finger wag.
So fragile.
Not just me then
😢
Me too....
@@LESLASLESLASaren't you edgy
I just can't drill metal without pouring some oil. It just doesn't feel right.
Просто прямые руки и острый глаз без всяких приспособ😉
Можно без приспособления наточить хорошо и с приспособлением наточить плохо. Один раз мне принесли цепь от бензопилы и видно что точили на станке, все зубья одинаковой длины и углы заточки совпадают. Только на одной стороне зубья заточены с острым углом, на на другом отрицательный угол заточки, я как увидел такое, в шоке был )))
I've been trying to learn to do this but I can't seem to get the point centered accurately. The drill bits I sharpen drill oversized holes. Although the video addresses the issue of getting the angle correct, it doesn't show anything to help center the point except "eyeballing" it.
Lol. Had to do it by eye a few times. Had a machinist scream at me. Also, need oil to keep the temper in tact. If it turns blue you're already screwed
Excellent ! The best I've seen so far.
thank you very much!
Great idea. I like to see how you do it. Thank you.
That's real cool, man.
Am I right in assuming that the same method can be used on a Sorby Pro Edge, with a 60 degree grooved metal plate, mounted on the adjustable shelf, set at 30degrees?
sharpen freehand with an angle grinder, when my drill bits are blunt. might not be perfect but they cut/drill very well, big improvement from blunt
В целом, грубо но эффективно это можно сделать просто при помощи ушм. Лепестковый или шлифовальный диск и пара минут аккуратной подгонки. Можно и на отрезном подправить заточку, просто дольше и чуть менее аккуратно. Зачастую острое сверло необходимо прямо сейчас, а до точила километров 200. На объектах только так и справлялись. Причём сверлили как тонкий металл (до1мм), так и швеллера с толщиной стенки 30-35 мм. Пользуюсь сверлами собственной заточки уже не один десяток лет.
Great tips there, ive always just eyeballed it, drawing the 60 deg line is a gamechanger alone
Чтобы заточить сверло нужно купить кучу инструмента и убить время на изготовление приспособ. Когда достаточно одного наждака.
Muy bueno, y yo afilando brocas siempre a ojo.
За то время пока идёт ролик Я заточил сверло на глаз и просверлил 20 отверстий🤦
Buy a drill sharping gage it has the correct angle (59 deg) and numbered lines to make sure the point in in the center. Sanders roll over the cutting edge a grinder is the only tool to use. I'm a tool and die maker we have a cutter grind department there are no sanders in it only grinders.
Посмотрел ролик, и понял почему китайские сверла, купленные в магазине от 6 мм и толще, никогда не сверлят металл. Они их затачивают как в этом ролике. 😊
... у них традиционно плохо с качеством металла и термообработкой , они сразу тупятся ... В своё время сначала Российско-имперская, а затем советская промышленность унаследовала стандарты качества металла от немцев, англичан и американцев (с поправкой на некоторые отечественные реалии), а китайцы как-то ... им надо всё быстро, много и дёшево. А не эти наши лаборатории на заводах, где образцы из каждой партии проката гоняются по всем тестам, плюс УЗК, рентген и прочее. Только производств и специалистов мало уцелело после всех безобразий и безумий
@@mikhaillinin4837 Вы правы на счёт того что все производства похерены и далеко не всё что произведено в современной РФ может сравниться по качеству даже с дешёвым Китаем. Но Вы отстали от времени - нынешний уровень Китая для РФ недостижим.
WOW!! This video is so educational. Thank you. Definitely will be doing quite a few of these ideas. 🙂
You forgot to mention that the cutting edges should end up the same length or the holes drilled will be oversize.
Ты прав , я думаю, что общие правила заточки свёрл известны уже лет 200.Так что автор этого сюжета практически заново открыл колесо!😅
Is that 6" sander just rotary or is it a random orbital? Double throw?
Very good!
We have become a use it and throw it away society but thankfully we are once again learning what our grandparents and great grandparents did with everything they owned! Maintenance was a daily and necessary part of their daily lives. With the increase in the price of everything we use its way more practical to sharpen our tools rather then throwing them into the scrap metal bin and running to town and buy more. This will be the next great re-discovery of the new age!
Если наша планета доживёт до следующего века!😢😢😢

これは凄いですね👍
Q. How can you ensure both (of the two) cutting faces are the same; as if not the same the one side of the drill will do all the cutting, until it is worn or becomes blunt ?
The easiest way is to use something called a drill point gauge. Technically you could just measure the length of the cutting edges with a machinist scale/rule as well, but the drill point gauge also includes the point angle. He approximated using nuts, but the actual angle is either 118 degrees or 135 degrees depending on the bit.
Needs a center cut lol i do that all by feel without any of that stuff. You really need a drill point gage to make sure both cutting edges are equal. Gotta mind that rekief angle as well. But for most folks, this is probably going to be a handy technique.
Полностью с тобой согласен.И ещё по поводу данного видео- дерево сверлят специальными сверлами другого вида или свёрлами по металлу, но с более острым углом заточки кромок сверла.
Saludos desde Mexico. Nice video.
The large diameter drills are relatively easier to sharpen. How about a video sharpening 1/8 bits.
Thanks
Sharpening a 1/8 bit is no different. 40 years as a toolmaker.
@@ronaldpatton5668 Totally agree with you. Over the years i ground 1000s of drill bits from 1/8 stubb drills up to 4", all by hand on a grinder. I've ground old drills off center so they bore slightly bigger from a tail stock and even left handed drills for certain m/c types. So yes you're 100% correct, from a fellow toolmaker!
Свёрла затачиваются одинаково и в Мексике, и в Африке, и в Японии!Привет из России с Донбасса!
Thank you! Finally someone who knows how to sharpen a bit. A wonderful "experianced" gentleman took me under his wing and taught me this I would have had to live 3 life times to learn. Howard Rilling. He showed me these methods. I took a couple he nuts and welded them together to keep as a gauge. He taught me how to twist and rotate down. I have seen so many people just twist it. You can use those hex nuts to gauge it to make sure the point is centered on the web to make sure a 3/8" drill bit drills a 3/8" hole. He also taught me that when a bit has spun in the chuck and raise a burr, to put the shank on a hard surface and pound the burr back down instead of grinding it off.
Thanks!!!
The tricky bit about sharpening drills without a fixture is getting the cutting edges the same length. I can sharpen a drill freehand well enough but not perfect due to having to estimate the equality of the cutting edges. I didn't see that the video overcomes this estimation.
One way is to put the drill bit in a hand drill, turn on drill and grind against grinding wheel at proper angle, then relieve the cutting edge. Another way is measuring the length of both cutting edges with a small rule and grinding down the short one till it is even with the longer one.
super impressive nonverbal communication and demonstration !
I learned the 1st method 38 years ago from an old guy, takes 30 seconds and I've had the same drill bits for years...👍
Thank you for sharing. Peace.
Nice I will have try these thanks
This is a great video which shows how to develop a skill. Instead of building a "life hack" or using an "incredible secret". There is nothing wrong with using a simple support as a reference. This sharpening method always works because of its simplicity. But you have to develop the skill and that is great. You always have it avaiable.
I have become a believer in Harbor Freight stuff. To sharpen drill bits, I use a small HFT belt sander, rest the bit on the tool rest at 67.5°, and gently twist the bit until it is sharpened.
without pointing out that you roll your hand as you drop the bit , this video is missing the most important part of the information.
I can see that you have old school skills and your video is excellent.
I learn sharpening over 50 years ago and I can see the merits of your jig.
Well worth making for anyone. Thank you for the video.
Nad touto metodou zůstává rozum stát. Profesionální brusiči mají oči plné slz smíchu...
K smíchu to moc není, jelikož se tím inspiruje spousta lidí. To je na basu...
great IF i owned a grinding wheel or a miller saw
Excellent, going to repair my old motorcycle side panels this way, cheers 👍

The VERY BEST part was the finger saying "NO,NO. !!
Comment fait - tu pour les petits diamètre ?
C'est intéressant pour un débutant en affûtage . Il faut expliquer les angles d'un forêt et surtout la dépouille si on veut maîtriser l'affutage des forêts de petit diamètre. Bonne vidéo.
Is the angle of a forest the direction trees grow towards the sun?
@@callmejackaroo4723 It's completely silly but it's poetic .
Lütfen Türçesini yazın.
Great video, thanks!
Typically, the cutting edges of a metal drill have an angle of 118 degrees!
Понравилась прижимка у сверлилки, никогда такой конструкции не видел, интересно.
Love the wagging finger 🤘
your vid 's led to an idea of having my wood lathe hold the drill bit. and work the sandpaper set on an angled slide to
do the tip grinding. evenly on both sides ... perhaps many other viewers thought of this too.
last eve for a bedtime read the 1964 time-life book ' machines' chapter on steam power was read . and the authors
cited how an ongoing series of ideas led to improvements over the years.
Sangat bermanfaat 🎉
Из под сверла должна идти скручивающаяся стружка и цвета металла, а не цветная кусками, тогда это правильная заточка. Автор пытался сделать доводку и только испортил, заточка такого сверла составляет 30 сёк на глаз, но нужен опыт
There's something so satisfying about sharpening drill bits by hand. You should include the importance of ensuring each flank/flute are the same length, so the bit doesn't favor one side of the cutting edge. Thinning the web is also another good step to include.
Отличный мастер. Жаль, что немой. Глухонемые все умеют работать руками
В ТАКИХ РОЛИКАХ, ВСЕГДА БЕСЯТ УКАЗУЮЩИЕ ПЕРСТЫ.
Simple trick. Thanks
Enfin ! Quelqu'un qui sait affûter les forêts.
*Please note that the placement of the wooden support block is crucial. Put it here **3:20** or maybe here **3:22*
*I'm not sure, but I think the number '60' is important here. I would have liked to have see that emphasised more. It's so easy to put captions into YT videos: I wish people would quit already with this "tap the thing several times" and "wag your finger for five seconds to indicate something you should avoid doing" rubbish.*
Agreed I thought that block has magically moved, yet there was no explanation why.
I suppose it makes sharpening easier in the second position.
Am I right that the same method can be used on a Sorby Pro Edge, with a 60 degree grooved metal plate, mounted on the adjustable shelf, set at 30degrees?
Bravo. Très instructif.Merci et bonne continuation.
Start from the back of the edge and go forward toward to the cutting edge. Better control! Anti clockwise.
Очень крутой уклон, большой минус такой заточки будет часто крошиться на самом конце сверла, и ещё раз, правильно заточено сверло должно гнать СТРУЖКУ а ту мелюзгу, тем более на станке!!!
Not a fan of the "hand model" approach but If you like it and it works for you thats great.
I have sharpened lots of bits and its not hard at all.
The cheap bits work just fine you have to sharpen them more often compared to the expensive brands.
The difference in price makes the cheap ones a better deal.
😂40 лет как то обходился без этой коряги, 10 лет им только дерево можно будет сверлить. А перемычку как на этом заточить ?
