Best technically sound Machine manufacturer , people can trust , I have 10 year experience
Thank you for uploading such an informative video.
@7:29 Firearm-Gun Barrel RPM=33375, is it right?
More around 3424rpm = Vc/3.14/d / 80000/3.14/d . With around 0,05mm material removed per turn of the tool. Seems legit to me. I'd not try to spin a 7,44mm drill with over 30k rpm :|☻
