Rebar is a low carbon steel alloy, you cannot harden it to any significant degree just by heat treatment. Also you have no clearance on the cutting teeth, this will not cut well at all.
I completely agree you need high carbon steel with a carbon content of between 0.5 to 1.5% carbon so the steel can be hardened and tempered. This tap will maybe cut a couple of threads in soft material such as copper or brass after that it will be as useless as a chocolate fire guard.
Won't cut, no relief behind cutting edges. Not tapered so first teeth would try to cut full depth, the rest would do nothing. It would be only useful as a thread chaser to get dirt or grease from an existing nut or threaded hole.
son muy laboriosos e inteligentes .pero como pais subdesarrolado al fin no tienen los recuersos ni los materiales idoneos es una gran pieza de artesania como comento alguyien oppero en la practica no puedee trabajar materiales de alta dureza
El acero de construcción, tiene cierta dureza, esa herramienta cumple perfectamente en metales relativamente blandos, como el fierro fundido, aluminio, bronce, etc. 👍
That's why buildings fall when hit by a major earth quake, they don't calculate G force effects of an earth quake when working out load bearing structures, where the load could get up to 4G, and as an electronic engineer I can say his skills are beyond any talented engineers in the west, they can do things the west is scared to do, that tap will happily cut softer metals and plastics, as long as the tapping hole is not under size, the swarf gets cleared by the rake angle or cutting angle which he did try and create by offsetting the slot at a slight angle instead of 90degrees.
Falto la prueba de corte en un metal para ver que tal trabaja ese material si es el proyecto final o es solo una prueba o muestra de como hacer un macho de roscado en el torno
Exacto. !! qual composicion del material? no cutting geometry, toooooo much drag, too much force, will break inside the part ! 'cause it's hard like glass.💎🤓
make that batch of rebar using assorted broken tool steel and carbide/cobalt tungsten light bulb filaments bits etc. cheaper just to use the rebar casting/forging setup?
Ese acero es SAE 1010 o a lo sumo SAE 1045 por más temple que le den sigue siendo dulce. Solo va a servir para hacer roscas en aluminio, bronce o plásticos
Rebar on the Rockwell Hardness chart is like Balsa on the Wood hardness chart! It's like choosing Aluminum ! Was that Salt you added to the quenching water? Wakodahatchee Chris
El problema con el hierro que se husa en la construcción no contiene suficiente carbono . Por lo que aunque se le de tratamiento térmico nunca podrá tener la dureza de el acero con el que se construye las herramientas en la industria. El acero con el que se hace esa herramienta tiene aleaciones de Molibdeno, Antimonio, Cobalto, Niquel y muy alto contenido de Carbono. Por eso tiene más dureza que la varilla que se husa en la construcción. O sea construyó una bella pieza de artesanías. Pero en la práctica no va a servir. No tendrá filo.
No cortará tal vez aluminio o latón pero perderá filo ni siquiera es una aleación de carburó de tugsteno , simplemente es una artesanía no es una herramienta de trabajo

As a Civil Engineer, I can say the concrete reinforcing steel has no hardness to make a tap from.

Good job Ustad

Nice job but that tap is just for show. Rebar will not harden and you meed to put in yhe reliefs to make that tap cut.
Everything is ok 😊👌
But flute position is not correct and heat treatment is not good.
Se eu tivesse esse torno compraria o macho na loja. 🤔
E tenho certeza que compraria uma botina e outros intens de epi

Felicitaciones por el ingenio que tienen por fabricar herramientas con material que se recicla para que no se varen. Dios los siga bendiciendo.

Looks like a tap but u can't use it as a tap🤗
it can cut only wood or plastic
make that batch of rebar using assorted broken tool steel and carbide/cobalt tungsten light bulb filaments bits etc. cheaper just to use the rebar casting/forging setup?
Unique idea for drill tap making
You forget putting it in oil

It's good but not strong enough for steel.
Good work but not best tap
Это делают для ролика, а ни для работы этим инструментом.
Come on guys, showing 'skill' and creating masterpiece are two different things 🤣
Test it how hard it would be or it will be useless....

news flash! man uses expensive metal working tools to make a thing out of metal! news at 11
As a man that did tool and die work for over 30 years this is bull shit
You just feel jealous and insecure because he’s more skillful than you. You never thought of this despite your 30 years of experience.

It would do fine with aluminum
Maybe this is just a practice piece before he gets some good stuff from a scrap yard somewhere.
It will be usefull for plastic material 🔥

What does that salt has to do with heat treatment I mean to say the logic behind.
