Lloyd ,
re-read your statement about feed rate vs tool radius . I find I get
the
best finish if the tip radius is larger than the feed rate ...

And yes, you do require a larger tip radius than the feed rate.

The thing about the edge radius is important, because most folks don't
have the ability to hand sharpen and hone a tool well enough to take off
a mere tenth.

Mostly (for hss) you just need to use an exceptionally hard and fine grit polishing stick..

I don't think I do anymore, and certainly not at the
cost/time of decent insert.
