Masonary Drill.
Masonry drills do not cost too much. Roughing out is easy.
Resharpen to a reasonable edge, push it in hard at about 0.002-0.004/rev and use lots of compound.
Maybe 200-300 RPM on a 3/4" drill. Suck it and see.
Shouldn't squeal.
Best of luck. Don't let it work harden.
Carbide and SS like each other. HSS is useless for production.

Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
