steel hardening technique which is not taught in school, make sharp spiral drill bits
a technique for hardening metal using salt water which is rarely known by mechanics.
Drill bit cutting with 2 spiral grooves. Correct drill bit grinding technique produces a sharp drill bit

Good for you mate, make what you need from what you got. One engineer to another, top work mate.
Thank you 👍
dril bit for wood?
enganou todo mundo. mostrou uma chapa de ferro e furou uma de aluminio muito mais grossa.
Con lo del imán si es hierro, pero la perforada es aluminio, no nos quieras engañar amigo.
Don't Waste your time making a drill with non appropriated steel. Showing us that is drilling 'through aluminum' but doesn't show the multiple sharpening.
Apakah aluminium nempel dengan kuat magnet ?😂
Hasil potong gram kecil kecil itu besi , jika aluminium akan panjang panjang ...

Le fer a béton n'a pas de carbone, c'est juste une cémentation qui a été réalisée. La durée de vie de ce forêt est d'un seul trou.
good job ....hope you the best..this Idea is so briliant...we are waiting for more and more every day as I hope ..thank you so much❤
Thank you 👍👍
The longer you watch, the worse it gets.
He's turning scrap iron into shiny scrap iron.
😄👍

Yeah, who needs instrument steel or high speed steel if rebars are all around. And drilling constructiln steel with construction steel was just magic.
Ну да. Разве, что пластмассу или дерево ими сверлить.
Ну, можно твердосплавную пластину ещё к концу (на суперклей с содой) приклеить.
Starts with drilling steel, swaps for aluminum then continues drilling.
A sham, but if it works for him then we'll done.
Kereen , ikut belajar abang ku
Silahkan 👍
😂😂😂😂 como se nota el cambio de pieza 👌
El acero coarrugado no es idoneo para templar !
Making drill bit of required size. Thanks
Cambio la plancha al final por una de aluminio, mas obvio no puede ser
Shows what you can do with what's on hand. I didn't realize that rebar could be hardened. What kind of salt was used in the quenching process? Was it ordinary table salt? Na Cl ? Amazing!
it's ordinary sea salt/tabble salt.
great stuff
At a minimum, drills are made of high-speed high-carbon steel. Here in the video the creation process is interesting, but it will not be practical. Made from a piece of construction reinforcement, the simplest and cheapest steel. Even with the proper degree of hardening, it will provide sufficient hardness of approximately 55-56 HRC, but it can only be used to drill simple iron, and even then not for long. I highly doubt that this drill will drill through steel sheet. Although, of course, it will be useful for drilling wood.
Fake... Es wurde vorgebohrt mit kleinerem Durchmesser... siehe ca. Minute 07:08 Und es sieht nach Alu-Platte aus...
Cool work thanks 👍
Nice Job ❤❤❤
SIZCE
A peça é de alumínio. O cavaco é branco.
ESA `PLAQUETA ES DE ALUMINIO!!!!
Rapaz ficou top dimais
🙏👍👍
Great!
Thanks
Good work
Yes nice one
Shouldn't you release a tension in steel with heating and slow cooling after the hardening? I just ask, don't know. Nice video 👍
Thank you
Das ist Quatsch. Einen Baustahl kann man nicht härten weil er zu wenig Kohlenstoff enthält.
أحسنت عملا . لكن عمل الثقب بهذه الطريقة خطأ . يجب إستخدام أرفع من هذه الشيء للثقب .👏
شكرا جزيلا 👍

In Italian schools the hardening technic is teached😂
👍👍👍
" só não vale pintar uma chapa de aluminio muito mais grossa e fingir de furar aço com uma porcaria de braca feita para enganar patetas"...
furou alumínio aí fura ferro pra nós ver
Show de bola ⚽ 🇧🇷❤️
Muito obrigado
Keep those toes back.
Bôt do là bôt gì
😮 ese material no da temple hierro sirve para perforar madera
👍
This is an aluminum plate.
😄👍🙏
Видео "сверло из гвоздя" Александр Популях посмотрите закалка графитовым порошком обробатовал и СТ3-,20и нержавеющей отверстия делал❤
Nice! How can the salt harden it?
Salt hastens the quenching process, which results in an increased hardness. In the interest of full disclosure, rebar comes in grades and this is likely made from from one of the stronger grades that has more carbon, making it possible to simply salt water quench and get the level of hardness needed for a cutting tool to be used on mild steel. Our friend is always showing us you can do what’s needed. You just gotta wanna...
@@ThisIsToolmanI'll take your word for it. if I were a more suspicious person I would say it doesn't make sense that there would be enough carbon in any rebar to be able to harden it. Furthermore, the plate he sticks to the magnet appears to be a quarter inch steel and the hole he drills appears to be on half inch aluminum. But I'm not sure why he would need to deceive anybody about this so so draw your own conclusions. I'm still suspicious that you can harden rebar except for surface hardening by adding carbon to the outer layer.
Friends have all answered your questions
@@virtualmarc2383 ASTM A615 Grade 100 rebar has a carbon content of 0.30-0.40%. Other standards in other countries may stipulate grading which could include more or less carbon of course. We don’t know what the standard might be for this Malaysian rebar.
I think if I were making this special size drill I would probably grind the point before hardening it, and then come back and touch it up, so as to take full advantage of the case depth.
A fine point (no pun intended), twist drills have a very slight reverse taper to alleviate rubbing.
You drilled Aluminium not steel. Why would you want to deceive viewers by testing with magnet then switching to aluminium. What steel chips like that?
Lá vai um ," não recomendar este canal " kkkkkkkkkkkkk 😂😂😂😂que bom
So a 250 dollar drill bit made from scrap...
كذاب .. هذه القطعة من الالمنيوم ولوكنت صادقا لقربت المغناطيس من الرايش الناتج من عملية الثقب
Арматура делается из отходов,знаю на своем примере,начал резать ножовкой по металлу не берет,посыпались зубья,отступил один сантиметр и как масло перерезал,так что в арматуре сплавлен и чугун и сталь,вообщем разные металлы
Как хорошо что русские такие необразованные.
Анонизм это тоже как вариант секса)))
Ne sont pas enseigner , faux, il faut dire ne sont plus enseigner, comme tous le reste, juste la décadence et la dégénérescence.
🙏👍
keren bubutnya
Terimakasih
🤣🤣🤣 proves that it is magnetic than uses a piece of aluminun he painted black....clown magic
You can't harden low carbon steel very much.
rebar may have enough carbon to harden a bit . that is why you don't weld regular rebar
Hidup jangan suka menipu.lama dipulaukan orang
Fake
bah oui!...
mais p-e pas en inde.
revenir sur la coupe... technique de peureux et lent.
👍
He first showed real steel and then replaced it with aluminum. We don't need your fake. We're sick of this whole Chinese fake thing.
🙏👍
Сам процесс возможно и не знаком многим. Но я увидел три нарушения правил техники безопасности. 1) Наждак без подручника.2) Баночка мала и стоит рядом с ногой. И 3) работник в босоножках. Вот и получается, что вреда в его материале больше, чем пользы. Модераторам хорошо бы отсеивать вредоносные методы работы.
😄👍👍👍👍
Parabéns belo trabalho.
Muito obrigado
its counstruction iron. low carbon steel, you cant do heat threatment. bullshit..
Thank you
yo mejor compro una sale mas barato y mejor
🙏👍👍
50 раз точил сверло. В арматуре нет углерода, поэтому это назьмо сыромятина и закалить не получится. Если только цементация, но чебуреки не знают что это 😁😁😁
If you can make a drill bit? why all the work?
For fun
