I figured you forged and twisted the flutes in! Very nice factory and efficient crew. Thanks for sharing. I heard the twist drill (the modern type for drilling steel) was invented in the 1860's by Henry Morse. It would be interesting to see how he originally did it.

I would love to see that too. When I first see the drill twisted by the forged machine, that's amazing.

Теперь я понимаю почему сверла из Китая имеют погрешность и при сверлении не дают точного размера. К стати; станки СССР

"Now I understand why drills from China have errors and don't provide the exact size before drilling. BTW, the machines were made in the USSR." Practicing my Russian.

thank you Jari, that process for oxide finish, under degree 560 degree, will have to take 2 hours then can release the stress of the drill bit. Thank you for your suggestion, We will see how to improve quicker.
