The iscar tools have a nose radius, but also have a short flat area

That sounds like you may already have wiper inserts, as long
ast your feed does not exceed .047 IPT. And that would be a high
feed indeed I think. Misplaced a decimal?

Here is the link to the actual insert

My main reason for thinking a wiper would give better finish, is taht
it would eliminate the small diferences in insert size/mismatch, and
seating mismatch within the cutter body.

Use a tenth's indicator and indicate the inserts in or use
matched inserts. What's the tolerance on the inserts? Stated
and checked on your real ones?

Have them in the correct cutter body for that flat to work?

I have an indicator that is able to indicate at 1/20 of a thou - I
will try seeing what the mismatch between teh inserts in the cutter is

(I know my spindle runout is about 2/10 ths)
