Yes it does. All those funny little letters C-N-M-G all mean something.

In quite a few different insert thicknesses it seems G.

In a CNMG? I've never seen that before. Unless it's a different IC. But
I'm
kinda hoping that would have been noticed. Now CCMT, CNMG and CCGT's are
different.


Hmmm.....

Off the top of my head, I'm recalling the first number is IC, the second is
thickness and with the third number being nose radius......gonna hafta
google I guess......

Yup :

I see three different thickness listed in that example G.

BTW, IF the thickness went with the IC you would
not need a designator for both.

"CNMG-FS" does not seem to tell us the thickness.

Insert shims .... and different toolholders ....
