Some of the best cutting ones are made of carbide...now they literally drill about anything

yep, even carbide can be no match for the abrasiveness of inconel. I hated machining that crap. Hastelloy X was another that can **** right off. Fun fact, the armor that surrounds the CPU in the black boxes of airplanes is made from solid blocks of inconel. When we machined them we used ceramic with no coolant (obviously) and spun the cutters at 18K rpm. Molten chips of inconel flying puts on a good show.
This video is mild. We threw steady streams of chips that actually melted the plastic safety windows on the machine lol.
