Food 15/20 degree vbit

[gdon_2003 (Guy Donham)]

I have a foos 15/20 degree vbit. I use the 15 degree a lot. The 20 degree has a rounded tip. Should I use it as a vbit or ball nose bit?

If you know the radius of the ball nose I would think you would use it as a ball nose. That’s how I have my tapered ball nose bits in the CC tool database.

If you use it as a V bit, it won’t carve properly. Everything will be much wider than the program expects.
