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. A couple of people have commented that these drills are low quality. The vid does start out that way, but the ones at the end look like much nicer ground flute drills to me. This video really needs more detail. I understand why it's not available, but it doesn't quite hit the spot for me.
@@MikeJones-rk1un But as you will know if you ever grind a drill accurately on a cutter grinder, it is almost impossible to make an accurate point if the the flutes have not been ground. You can buy quality ground flute drills and plain forged ones. The forging can occur early in the production process and it is seen in this video. You can also fully grind a helical flute into a cylindrical drill rod blank. What I suggested was that you can't see if they actually show flute grinding process if it occurs on their forged drills. They do appear to show finished ground flute drills in the video, so I found it a rather frustrating presentation. I can't say that I feel you helped me with that, because many of those who expect good results from their drills used on hard materials know that they need ground flutes. It allows them to be resharpened accurately when they inevitably wear out. Lousy drills are formed by forging only. Both ground flute and forged drills are twist drills, because you twist them to make them cut.
@@MikeJones-rk1un You aren't going to do that with a solid carbide drill however; those things are expensive because they must be ground from a solid bar.
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.
Thank you for your kindness, we have the responsibility to inform the factory to pay attention to protect the health of workers in the later production.
@@mikegrok the only time they were brought close to a hardening temperature was when the flutes were put on the bits. They just dropped into a bin from there.
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.
You can by drills using tool steels instead of carbon steel bits, but they do cost more. Look for drills using HSS or M2. M2 are tungsten-molybdenum tool steel and will last a long time. Even harder are Tungsten-carbide, but aren't suitable for some drilling & they are brittle compared to HSS/M2 tool steels.

This would have been better if the person filming would have been able to show exactly what each step of the process is in detail and how the machines work.
@@wiser1147 Yes. There are three rotating forming dies that pull and rotate the drill rod blanks forward, causing the drill rods to rotate as they are pulled forward by the dies. The rotating forming dies create the spiral flutes.
- Yep, that's a reason why 10-15% of Chinese drill bits need to be resharpened from a box. Only Russian drill bits is worse: 30+% is bad sharpened, and just cannot drill. I've tested it many times before the war in 1990-th and later. Soviet drill bits where manually checked, at least - later quality level much downgraded.
They pump them out as fast as they make toothpicks, unfortunately most of these are only high carbon steel not toolsteel and can only be hardened to a certain hardness and do not stay sharp for long especially drilling steel. People keep buying them because there inexpensive and lots available 😎

You mean that for strong and definitive convincing, we need to view the way things made in China? When things in China can be made (no, correction) ARE being made from cheapest and most inferior of quality as raw material, no convincing is needed that they profit from masses of buyers of 'cheaper' products produced.
