С использованием такого принципа поворота теоретически затыловка отсутствует. Неудачный ракурс для заточенного сверла не позволяет увидеть это. Но результат сверления, когда металл крошится, а не снимается стружкой, косвенно подтверждает этот вывод.
Нормальная заточка. Так же можно качать сверло вертикально. Накой хрен спиральным свёрлам с такой геометрией режущей части нужна затыловка(это не так называется!) ???
There is one more complicated type to make but it works better(you can adjust all angles and even grind a split point) and that is Lisle grinder.Abom and mr pete have dissasembled one and you can find pictures in manuals. But you need advanced machines for it like lathe and milling machine.Still it would be cool to see one built for bench grinder.
Love the blue colour. Not so good to use the edge of the wheel if you have a few drills to do. It would be nice to be able to cool the drill in liquid if it gets hot. Very lovely video all the same.
Wow, nice video, but home made? That's quite the machine shop and processing. The inclinometer was a cool touch. I suspect that building this is well beyond most home shops.
Well at least I now know there's at least 2 people who knows that drill he sharpened looked a whole lot better before he sharpened it than after he sharpened it
good mechanical work, but I see that many special tools are necessary for the construction of the device. I'm sure it's better to learn how to sharpen drill bits by hand. You can also purchase the drill bit sharpener for little money.
ever have a grinding wheel blow up in your face? well, keep grinding on the side of the wheel like that and you'll find out how unpleasant it is when they blow up and shatter... they sound louder than a 12 guage shotgun going off...
Mmmm, I was thinking the same thing. The more drill bits you have to sharpen, the more you are doing the wrong thing. So a bit of a shame in this regard.
Mauvais affutage, les copeaux le prouvent. De plus, il ne coupe que sur une lèvre. L'affutage sur le coté de la meule est dangereux avec une meule non adaptée et c'est le cas. L'angle le plus important, hormis la symétrie, est la dépouille (2° pour l'acier) L'angle de 120° n'est utile que pour limiter l'usure du foret et est surtout valable dans l'industrie, en utilisation amateur c'est accessoire, 85 à 120° sont recommandable.
Всё как би аккуратно и правильно . Но много не нужного. Может и ошибаюсь но вариант попроще и заточка отличная. th-cam.com/video/8qheM_Z-z-Q/w-d-xo.htmlsi=gnLu0xxAk1Up90Kt
Please do not sharpen your bits like this as you will damage the integrity of the grinding wheel and centrifugal forces will make it fracture and if it breaks whilst you are in front of it the wheel will injure you. not worth the risk sorry
Nice build. We shared this video on our homemade tools forum this week 😎
Good job,I like it!
Aprovado valeu muito obrigado!.
Parabéns muito seu vídeo

@@kotleta4634 Ну во обще то она уменьшает трения сверла по металлу....хотя бы для начала ....
Нужно державку с другой стороны привернуть через гайку . тогда будет нормальная затыловка
@@kotleta4634 без "затыловки" в 8-12 градусов сверло будет не резать, а "гладить" металл.

Gabarito perfeito

Хорошая приспособа и сделано аккуратно. Понравилось.
muy buena explicacion y buen invento, pero siempre videos con brocas grandes que tal si lo haces con una broca de 1 mm seria digno de ver
Wow, nice video, but home made? That's quite the machine shop and processing. The inclinometer was a cool touch. I suspect that building this is well beyond most home shops.
Boa ideia ese gabarito para afiar brocas
excellent thank you
yess!
Amigo, parabéns esse torço é de mais.
Faça pra vender.
The sharpened drill struggles to drill and the chips formed are incorrect. A correctly sharpened drill will give curly chips when drilling.
Well at least I now know there's at least 2 people who knows that drill he sharpened looked a whole lot better before he sharpened it than after he sharpened it
Grinding wheels are made to be used on the side of the wheel. Other than that, nice set up.
Yeah go ahead,grind on the side of a bench grinder removing tons of material and when that wheel hits you between the eyes - do not blame me!
@@martintheron1386 Rereading my post that you replied to, I meant to say that "grinding wheels are NOT made to be used on the side...."
Great project, if you looking for a project, but you can buy a commercial one for less than $20, I believe.
с такой перемычкой хер оно будет сверлить без расверловки
good mechanical work, but I see that many special tools are necessary for the construction of the device. I'm sure it's better to learn how to sharpen drill bits by hand. You can also purchase the drill bit sharpener for little money.
Great video, but don't use the side of A grinding wheel. (Only the face narrow part)
They can explode.
Parabéns pelo vídeos,
Gostaria muito de ter um desses
Muy buena idea ,perooo hay que lubricar la broca, sino se destampla
Pretty cool :D
Сделано неправильно нет наклона поворотной стойки ,для того чтобы получалась затыловка
Наклон вертикальной оси должен быть на 12,5 градусов.
But why when you can buy one for like $10?
Boa tarde vc faz essa ferramenta para vender
Never buff on the side of the wheel
Где-то режущего угла не хвотает а так отлично
👋👍👍👍
Mantap mantap 👍👍
Ten čap na ktorom sa robí pohyb pri brúsenie má mať sklon. Vrták na tom to prípravku je zle nabruseny, nevrtá, frezuje.
A jak naostrzyć wiertła o małe średnicy od fi 3 do 0,3 mm?.
Tie sa brúsia ručne pod lupou.
Gut
OG tac welder
забыл 13-15° наклон для вертикальной оси
Správne, chýba tam sklon na tom čape. Po nabruseny vrták nevrtal ale frezoval.

i' will pay 200 usd$ for one of these units complete. u take paypal?
Available on amazon and ebay.

Hacer este afilador de mechas es más fácil que pelar mandarinas , dejo que lo vean elementos como ustedes que les funciona poco la masa gris .

You don’t need crap like this. Learn to hand sharpen.
