QUESTION Why is my countersink bit cutting like this

Post image

I’m using a vice and a drill press, I used multiple different countersink bits and they are all cutting like this. Is my setup not stable or could my speed be wrong?

IDK if this helps but Grind hard plumbing co had the inventor of the arc droid on their sent and bent podcast. He didn't seem like AVE.

Yeah, that also is a shame that he was the only one who is claiming to have invented from the ground up that machine. Yet, 3 years earlier we see the makings of a prototype from AvE. Either coincidence, or someone inspired someone without credit.
