Re: CB360's - Speak No Evil, See No Evil, Hear No Evil (and eventually, just EVIL)
I don't go through all that nonsense, just use high speed steel, low speed and 'enough' pressure.
The center drills are Harbor Freight specials, the 1/4" is a Dewalt Ti coated
I think drill is set at around 250~300rpm (haven't looked at it for years)
Stainless work hardens really quick if you back off pressure or have drill bit spinning too fast
As for pressure, that's an experience/practice thing
The 'pattern' is a 'nul' pattern
If you imagine some swirly diagonal lines it may show up? ;D
