No eye protection, no ear protection, no safety guards on rotating machinery. Now we know why stuff is so cheap from there.

[@marksturgis3536]

That explains some of my cheapest drill bits.

[@1992jamo]

Ah got it. The hot metal goes in, and the drillbits come out, I feel like I've learned so much.

[@someoneelse7629]

Oh, I know this brand, they come predulled from the factory, and that's good, because if you sharpen them and eventually get them to catch, they will unwind the flutes.

[@andyash5675]

It's a bit of a shame that you don't get to see how the flute forging and then the tip grinding machine actually works. Obviously it's difficult because the important steps happen behind a guard.

Hand grinding drill bits w/o eye protection for hours on end without eye protection is insane and upsetting to watch. I guess leaving the induction heater and dropping into a bucket is sufficient heat treatment.... Odd. I guess they're just carbon steel and not hss steel so salt bath heat treatment or furnace operations followed by quenching aren't necessary. The productivity is certainly impressive.

[@kennyparis8742]

Now I know why I'm sharpening bits after 2 holes. I'll put every bit I have in the forge and oil quench them tomorrow. They don't do anything to harden them.

[@Adventures_with_Josh]

And now I know why my bits cut like shit right outta the box🤦

[@andrebartels1690]

I will treat my cheap drill bits with more respect from now on, since I know someone made them in hard work.

[@MacGyver-1]

Good thing they can make them so quickly, you need 4 just to drill one hole

[@RosCug]

Respect to the workers.

Спасибо за видео очень интересно. Всем привет из России.

[@feynthefallen]

So they just magically turn from iron rods into drill blanks. Wow. Seriously, content like that I can do without.
