I guess he found some ultra rare CNMG-411-FS inserts. I wonder if
they are the unobtanium grade.

The exact type under green plastic package is:
"CNMG120408-FS NX2525
CNMG432FS"

On top of package there are listed cutting speeds
for stainless (70-150 m/min) and steel (210-300 m/min).
So these are obviously meant for steel also.


Your depth of cut is way too small for such a large nose radius. You should
leave a minimum of .054mm (2/3)DOC for that radius. Better yet would be to
use a CNMG 431 or 430 insert for finishing.
